1
00:00:00,320 --> 00:00:02,960
Speaker 1: Ron Ananian. I guess the bigger part of this job

2
00:00:03,040 --> 00:00:04,040
Speaker 1: is to educate people.

3
00:00:04,160 --> 00:00:16,520
Speaker 2: It's to explain to them what happens and why.

4
00:00:17,640 --> 00:00:18,599
Speaker 1: The Car Doctor.

5
00:00:18,800 --> 00:00:21,920
Speaker 2: My memory is most of those trucks steered fairly well.

6
00:00:22,120 --> 00:00:22,680
Speaker 1: They weren't.

7
00:00:22,760 --> 00:00:25,280
Speaker 2: They weren't terrible out of the factory. There were ways

8
00:00:25,280 --> 00:00:27,479
Speaker 2: to make them better, but they weren't terrible to begin with.

9
00:00:28,200 --> 00:00:30,080
Speaker 3: So that's my second one.

10
00:00:30,120 --> 00:00:32,639
Speaker 1: This was my second one, and all, welcome to.

11
00:00:32,600 --> 00:00:36,080
Speaker 4: The radio home of Ron Ananian, the Car Doctor. Since

12
00:00:36,159 --> 00:00:39,320
Speaker 4: nineteen ninety one, this is where car owners the world

13
00:00:39,400 --> 00:00:43,919
Speaker 4: overturned to for their definitive opinion on automotive repair. If

14
00:00:43,920 --> 00:00:46,680
Speaker 4: your mechanics giving you a busy signal, pick up the

15
00:00:46,680 --> 00:00:47,880
Speaker 4: phone and call in.

16
00:00:48,320 --> 00:00:50,440
Speaker 1: The garage doors are opening, but.

17
00:00:50,400 --> 00:00:52,400
Speaker 2: I am here to take your call at eight five

18
00:00:52,560 --> 00:00:53,920
Speaker 2: five five six ninety nine.

19
00:00:53,880 --> 00:00:55,360
Speaker 3: Hundred and now he.

20
00:00:57,960 --> 00:00:58,280
Speaker 2: Running.

21
00:00:59,080 --> 00:01:01,080
Speaker 1: Hey, hello and welcome. My name and the card Octra.

22
00:01:01,640 --> 00:01:04,080
Speaker 1: Hold the applause, Hold the applause. Enough.

23
00:01:05,600 --> 00:01:09,000
Speaker 2: Gee, now I know what Johnny went for a there

24
00:01:09,040 --> 00:01:12,399
Speaker 2: you go. Let's settle down. Settle down. I know the

25
00:01:12,440 --> 00:01:18,120
Speaker 2: fan list is growing. Okay, let's let's get to work.

26
00:01:18,120 --> 00:01:19,960
Speaker 2: You know, it was a busy week in the shop.

27
00:01:20,000 --> 00:01:22,319
Speaker 2: We had a lot going on, as we always do.

28
00:01:22,400 --> 00:01:24,080
Speaker 2: We solved a bunch of problems and we're here to

29
00:01:24,120 --> 00:01:26,160
Speaker 2: talk to you about them as well as solving your problems,

30
00:01:26,480 --> 00:01:28,200
Speaker 2: because that's what the car doctor likes to do. The

31
00:01:28,240 --> 00:01:30,360
Speaker 2: other thing we're gonna do is we've got four race tickets,

32
00:01:30,520 --> 00:01:33,120
Speaker 2: the last four I found more. I was kidding before

33
00:01:33,280 --> 00:01:35,640
Speaker 2: I found the last four race tickets to give away.

34
00:01:35,720 --> 00:01:38,679
Speaker 2: So if you've got nothing to do July twenty thirty,

35
00:01:38,680 --> 00:01:40,560
Speaker 2: and you're gonna be in the neighborhood of the Pocono's,

36
00:01:40,600 --> 00:01:44,600
Speaker 2: the Pocono four hundred, the Tricky Triangle, we've got four

37
00:01:45,080 --> 00:01:48,080
Speaker 2: two hundred level race tickets to give away. Paddocks plus

38
00:01:48,120 --> 00:01:52,440
Speaker 2: passes down there, viewing deck, victory lane, driver appearances, autograph valley,

39
00:01:53,520 --> 00:01:55,800
Speaker 2: you know, the whole nine yards there. I'm using that

40
00:01:55,840 --> 00:01:59,360
Speaker 2: expression again this weekend, and we look forward to seeing

41
00:01:59,400 --> 00:02:01,720
Speaker 2: we've got two. It's per fam I've got so I've

42
00:02:01,760 --> 00:02:04,520
Speaker 2: got two sets to give away this hour. So if

43
00:02:04,560 --> 00:02:06,280
Speaker 2: you've got a question, give us a call. Decision of

44
00:02:06,320 --> 00:02:09,320
Speaker 2: the judge Tom is final and'll be nice when you

45
00:02:09,320 --> 00:02:12,520
Speaker 2: talk to Tom. He gets snarly. You know after certain

46
00:02:12,560 --> 00:02:16,639
Speaker 2: times in certain events, things like that happened for him.

47
00:02:16,760 --> 00:02:18,480
Speaker 2: I want to talk a little bit about where we

48
00:02:18,600 --> 00:02:20,520
Speaker 2: going here. Let's go over to Frank. Frank's been waiting

49
00:02:20,600 --> 00:02:23,120
Speaker 2: very patiently in my pile of papers.

50
00:02:23,160 --> 00:02:23,320
Speaker 5: Ron.

51
00:02:23,320 --> 00:02:25,080
Speaker 2: I've got a sixty eight Corvette. I've been sick and

52
00:02:25,120 --> 00:02:27,720
Speaker 2: recently had triple bypass surgery. The car has been sitting

53
00:02:27,760 --> 00:02:29,360
Speaker 2: for over eighteen month. Do you think I should move

54
00:02:29,360 --> 00:02:31,720
Speaker 2: the valve covers and pour some oil down there? Thanks

55
00:02:31,720 --> 00:02:33,720
Speaker 2: Frank from Pennsylvania. I can't wait for your show. This

56
00:02:33,800 --> 00:02:35,800
Speaker 2: was from last week. Sorry, Frank, I didn't get to

57
00:02:35,800 --> 00:02:38,600
Speaker 2: it last week. Yeah, you know what, Frank, I think

58
00:02:39,200 --> 00:02:42,560
Speaker 2: it's been sitting right, and I don't think we talked.

59
00:02:42,560 --> 00:02:45,560
Speaker 2: We actually had a call from a sixty eight Corvette

60
00:02:45,960 --> 00:02:48,240
Speaker 2: listener for lack of a better way to say it,

61
00:02:48,800 --> 00:02:52,240
Speaker 2: a few weeks ago, and I think that was different.

62
00:02:52,280 --> 00:02:54,120
Speaker 2: But because yours actually runs, I think his has been

63
00:02:54,120 --> 00:02:57,799
Speaker 2: sitting longer, more so than moving the valve covers. If

64
00:02:57,840 --> 00:03:01,760
Speaker 2: you want pull the distributor out and you know, just

65
00:03:02,200 --> 00:03:03,880
Speaker 2: prime with an oil pump. You know there are oil

66
00:03:03,880 --> 00:03:06,440
Speaker 2: pump primers available. You can find it on Summit, you

67
00:03:06,480 --> 00:03:08,440
Speaker 2: can find it in any of the speed shops online.

68
00:03:09,080 --> 00:03:11,040
Speaker 2: You could actually make one out of a small block

69
00:03:11,120 --> 00:03:13,800
Speaker 2: Chevy distributor. Just you know, drive the rollpin out, take

70
00:03:13,840 --> 00:03:16,000
Speaker 2: the gear off, put the bottom half of it in there,

71
00:03:16,560 --> 00:03:18,880
Speaker 2: attach it to a drill. That's basically what the primers are.

72
00:03:19,240 --> 00:03:21,600
Speaker 2: And if you're that worried about it, spin the oil

73
00:03:21,600 --> 00:03:24,760
Speaker 2: pump around, you know, or if you want disabled spark,

74
00:03:26,280 --> 00:03:28,800
Speaker 2: you know, just just disable the spark once there's no

75
00:03:29,040 --> 00:03:35,080
Speaker 2: load by virtue of a of a spark ignition happening

76
00:03:35,080 --> 00:03:38,120
Speaker 2: inside the cylinder to crank it around. After eighteen months,

77
00:03:38,240 --> 00:03:40,320
Speaker 2: I don't think it's going to matter all that much.

78
00:03:41,000 --> 00:03:43,400
Speaker 2: It's a sixty eight. I've done it myself more than

79
00:03:43,400 --> 00:03:46,200
Speaker 2: a few times. My bigger concern would be that valve

80
00:03:46,200 --> 00:03:47,920
Speaker 2: springs have been sitting in the same position for the

81
00:03:47,960 --> 00:03:49,800
Speaker 2: past eighteen months, and you can pour all the oil

82
00:03:49,800 --> 00:03:51,720
Speaker 2: in the world you want down there and it's not

83
00:03:51,880 --> 00:03:54,080
Speaker 2: going to affect it or make things better. But if

84
00:03:54,120 --> 00:03:56,360
Speaker 2: you're that worried about it, you know, pouring oil down

85
00:03:56,360 --> 00:03:58,200
Speaker 2: the valve covers doesn't do anything. You don't get to

86
00:03:58,200 --> 00:04:01,600
Speaker 2: the bearings, you don't get to, you know, internals you're

87
00:04:01,600 --> 00:04:04,920
Speaker 2: worried about. If you're worried about lack of oil coating

88
00:04:04,920 --> 00:04:06,640
Speaker 2: and there should be some there. It has a cling

89
00:04:06,680 --> 00:04:09,400
Speaker 2: factor to it, you know, Like I said, don't let

90
00:04:09,400 --> 00:04:12,000
Speaker 2: it fire. Within fifteen to twenty seconds you should see

91
00:04:12,040 --> 00:04:14,560
Speaker 2: oil pressure. And then once you do that, you want

92
00:04:14,600 --> 00:04:17,160
Speaker 2: to crank it around. You've got oil. Then start it

93
00:04:17,200 --> 00:04:19,560
Speaker 2: up and let it idle. And you know, depending upon

94
00:04:19,560 --> 00:04:21,320
Speaker 2: when the last time the oil was changed prior to

95
00:04:21,360 --> 00:04:24,400
Speaker 2: you letting it sit for eighteen months before you got sick,

96
00:04:24,560 --> 00:04:26,600
Speaker 2: you know, maybe you change it before, you definitely change

97
00:04:26,600 --> 00:04:28,920
Speaker 2: it after, you know, you should be good from there.

98
00:04:28,920 --> 00:04:30,640
Speaker 2: I'm glad to hear you up and around, and I

99
00:04:30,680 --> 00:04:33,599
Speaker 2: wish you well in a speedy recovery. So, like I said,

100
00:04:33,640 --> 00:04:36,080
Speaker 2: just oil pressure from priming within or just cranking it

101
00:04:36,400 --> 00:04:40,240
Speaker 2: disconnect the spark, I think you'll be fine in most cases.

102
00:04:40,240 --> 00:04:42,920
Speaker 2: And I've never seen a failure, you know, eighteen months. Yeah,

103
00:04:42,920 --> 00:04:45,120
Speaker 2: and if it cranks, that's a good sign. That means

104
00:04:45,120 --> 00:04:46,520
Speaker 2: it's got oil there, it's still moving.

105
00:04:46,880 --> 00:04:48,560
Speaker 1: So let's go over to the phones.

106
00:04:48,640 --> 00:04:51,119
Speaker 2: Let's go to Joe and Iowa twelve f three fifty

107
00:04:51,200 --> 00:04:53,560
Speaker 2: and an intermittent no crank condition. Joe.

108
00:04:53,600 --> 00:04:55,200
Speaker 1: Welcome to the car doctor, sir, How can I help?

109
00:04:56,440 --> 00:04:58,320
Speaker 6: Yeah? Thanks, Ron, you're welcome.

110
00:04:58,360 --> 00:04:58,520
Speaker 5: Hey.

111
00:04:59,480 --> 00:05:02,240
Speaker 6: So that that what it does when you go to

112
00:05:02,240 --> 00:05:04,600
Speaker 6: turn put the key on and try to crank it.

113
00:05:04,600 --> 00:05:09,080
Speaker 6: It it's you'll start sometimes and sometimes it won't start,

114
00:05:09,120 --> 00:05:11,839
Speaker 6: and I should say crank. It won't crank sometimes and

115
00:05:11,920 --> 00:05:16,880
Speaker 6: it will at other times and start. So I'm kind

116
00:05:16,880 --> 00:05:19,360
Speaker 6: of wondering. I cleaned the battery terminals and all that.

117
00:05:19,400 --> 00:05:23,479
Speaker 6: It is my kid's truck. And he took the battery

118
00:05:23,520 --> 00:05:26,440
Speaker 6: to the shop or the one of the old rillys

119
00:05:26,440 --> 00:05:28,839
Speaker 6: I think it was, and they said the battery is bad,

120
00:05:28,880 --> 00:05:30,800
Speaker 6: so you put a new battery in it and say

121
00:05:31,000 --> 00:05:35,320
Speaker 6: same thing, and wouldn't start. And then I went ahead

122
00:05:35,320 --> 00:05:38,360
Speaker 6: and was messed with it myself, and I thought, well,

123
00:05:38,400 --> 00:05:41,200
Speaker 6: I'm just going to clean the term connections there at

124
00:05:41,240 --> 00:05:45,520
Speaker 6: the starter, and I cleaned the ground and the large

125
00:05:45,800 --> 00:05:49,719
Speaker 6: positive cable and and then at the starter and I

126
00:05:49,800 --> 00:05:53,119
Speaker 6: cleaned the small you know wire, the positive wire there,

127
00:05:53,520 --> 00:05:55,720
Speaker 6: and I when I had my wife, I had her

128
00:05:55,760 --> 00:05:57,960
Speaker 6: turn the key to the crank position. And I'm not

129
00:05:58,000 --> 00:06:02,200
Speaker 6: getting any voliage on that small way, Okay, right, so let's.

130
00:06:01,960 --> 00:06:04,159
Speaker 2: Go let's go back. All right, let's go back to

131
00:06:04,200 --> 00:06:07,000
Speaker 2: the ignition switch. Higher mileage truck Joe.

132
00:06:08,160 --> 00:06:09,760
Speaker 6: Yeah, I think I'm not sure. One hundred and twenty

133
00:06:09,760 --> 00:06:10,719
Speaker 6: thousand mileage.

134
00:06:10,520 --> 00:06:12,960
Speaker 2: Okay, higher mileage. A lot of key cycles in one

135
00:06:13,000 --> 00:06:16,600
Speaker 2: hundred and twenty thousand miles, you know. So let's let's

136
00:06:16,680 --> 00:06:20,080
Speaker 2: let's take the steering column clamshells off so you can

137
00:06:20,120 --> 00:06:22,200
Speaker 2: get to the wiring leading up to the ignition switch.

138
00:06:22,200 --> 00:06:23,599
Speaker 1: If you want to get this deep. This is where

139
00:06:23,640 --> 00:06:24,080
Speaker 1: I would go.

140
00:06:24,040 --> 00:06:27,440
Speaker 2: With this because I've I've I've done this, I've seen this.

141
00:06:27,440 --> 00:06:31,200
Speaker 2: This is not an uncommon problem. So coming into the

142
00:06:31,200 --> 00:06:34,200
Speaker 2: ignition switch, you're going to have a series of wires.

143
00:06:34,240 --> 00:06:36,040
Speaker 2: There's going to be a green with a red stripe.

144
00:06:36,040 --> 00:06:38,559
Speaker 2: Green with a red stripe is power off a fuse

145
00:06:38,640 --> 00:06:41,640
Speaker 2: number twenty eight coming out of the underdash fuse box.

146
00:06:42,000 --> 00:06:45,960
Speaker 2: All right, So green with red is power in when

147
00:06:46,000 --> 00:06:49,560
Speaker 2: it goes into this no crank condition. Does green with

148
00:06:49,640 --> 00:06:53,520
Speaker 2: red show power It usually does, all right? Just just

149
00:06:53,560 --> 00:06:56,440
Speaker 2: to be clear, and you know, the way I would

150
00:06:56,680 --> 00:06:58,920
Speaker 2: the way if I was diagnosing this as an intermittent

151
00:06:58,920 --> 00:07:01,520
Speaker 2: for a customer, the way I would the way I

152
00:07:01,520 --> 00:07:03,280
Speaker 2: would set this up. And you guys have heard me

153
00:07:03,320 --> 00:07:06,320
Speaker 2: talk about this before. This is the classic one ninety

154
00:07:06,320 --> 00:07:09,240
Speaker 2: four side marker bulb set up. All right, where I'm

155
00:07:09,279 --> 00:07:12,360
Speaker 2: gonna go down to my local Loto parts store. You know,

156
00:07:12,400 --> 00:07:14,480
Speaker 2: if you've got an AutoZone near you, run down to

157
00:07:14,480 --> 00:07:16,160
Speaker 2: your local Loto zone. Tell them you're looking for one

158
00:07:16,240 --> 00:07:20,280
Speaker 2: ninety four side marker bulbs. And you know you'll understand

159
00:07:20,280 --> 00:07:21,800
Speaker 2: it when you see it's just a little tiny it's

160
00:07:21,840 --> 00:07:24,040
Speaker 2: just a little tiny marker bulb. And then you're looking

161
00:07:24,080 --> 00:07:26,560
Speaker 2: for a socket, a socket with two wires on it.

162
00:07:26,960 --> 00:07:29,880
Speaker 2: All right, get a get a wiring diagram to verify.

163
00:07:30,280 --> 00:07:32,720
Speaker 2: But if I remember it right, green red is power in.

164
00:07:32,800 --> 00:07:35,360
Speaker 2: Blue white is power out. All right, But like I said,

165
00:07:35,400 --> 00:07:38,120
Speaker 2: look at a wiring diagram, find a place to access

166
00:07:38,160 --> 00:07:40,600
Speaker 2: the harness and cut those wires. Take the green red,

167
00:07:40,680 --> 00:07:43,680
Speaker 2: run it run run the bulb in between. So now

168
00:07:44,000 --> 00:07:46,520
Speaker 2: when you're driving, when you go to crank, you're gonna

169
00:07:46,560 --> 00:07:48,160
Speaker 2: have power coming up that green.

170
00:07:48,000 --> 00:07:49,760
Speaker 1: Red, the bulb will be lit.

171
00:07:50,280 --> 00:07:53,520
Speaker 2: And if the switch is making contact, you know, at

172
00:07:53,560 --> 00:07:56,480
Speaker 2: the circuit's coming through, what's gonna happen to the bulb

173
00:07:56,520 --> 00:07:59,640
Speaker 2: on the blue white, It's gonna be lit right that

174
00:07:59,640 --> 00:08:01,960
Speaker 2: that that blue white is the feed out to the

175
00:08:02,000 --> 00:08:07,360
Speaker 2: starter relaying circuitry. If if you don't have power out,

176
00:08:07,560 --> 00:08:10,520
Speaker 2: all right, then, and you've got power in and you're

177
00:08:10,560 --> 00:08:14,640
Speaker 2: at the switch. It's one of two things. It's either

178
00:08:14,680 --> 00:08:19,920
Speaker 2: a bad switch, okay, or something in the steering column.

179
00:08:19,960 --> 00:08:22,280
Speaker 2: And I've seen this too, and this will mislead you.

180
00:08:22,760 --> 00:08:26,080
Speaker 2: Something in the steering column is preventing the ignition switch

181
00:08:26,360 --> 00:08:28,360
Speaker 2: from moving all the way forward.

182
00:08:29,120 --> 00:08:31,760
Speaker 1: So right, so.

183
00:08:31,760 --> 00:08:34,280
Speaker 2: You've got to be sure that you're able to get

184
00:08:34,280 --> 00:08:36,920
Speaker 2: it into that crank cycle where it's you know, it

185
00:08:36,960 --> 00:08:40,720
Speaker 2: feels spring loaded, that it would come back all right, yeah,

186
00:08:40,760 --> 00:08:43,840
Speaker 2: you know, don't don't be misled by that. You know, Now,

187
00:08:43,880 --> 00:08:45,920
Speaker 2: if you can get if you can get this to fail,

188
00:08:46,600 --> 00:08:48,160
Speaker 2: which it sounds like you can get it to fail

189
00:08:48,160 --> 00:08:49,720
Speaker 2: on a regular basis. You don't need to do the

190
00:08:49,760 --> 00:08:53,160
Speaker 2: sidemark or ball routine. You can just have your vaultmeter handy,

191
00:08:53,240 --> 00:08:55,920
Speaker 2: have the column covers off, and I would tell you

192
00:08:55,960 --> 00:08:58,079
Speaker 2: to do this. I would tell you to test your

193
00:08:58,080 --> 00:09:03,120
Speaker 2: green red and your blue white when when it works, right,

194
00:09:04,400 --> 00:09:06,360
Speaker 2: don't don't wait for it to break. If you know

195
00:09:06,400 --> 00:09:08,840
Speaker 2: what good looks like, you're gonna know what bad looks like.

196
00:09:10,720 --> 00:09:14,080
Speaker 6: Right, Yeah, yeah, So I'm kind of curio, That's what

197
00:09:14,160 --> 00:09:16,240
Speaker 6: I was kind of thinking to you know, starting at this,

198
00:09:16,400 --> 00:09:18,480
Speaker 6: maybe the switch or I mean I did look at

199
00:09:18,480 --> 00:09:20,760
Speaker 6: the relays and stuff, but I kind of thumped on

200
00:09:20,800 --> 00:09:22,640
Speaker 6: the relay when my wife tried to crank it and

201
00:09:22,679 --> 00:09:24,800
Speaker 6: thinking it if it was relay, it would you know,

202
00:09:24,880 --> 00:09:29,079
Speaker 6: maybe uh make contact, but didn't have any couldn't get

203
00:09:29,080 --> 00:09:32,640
Speaker 6: that to work. Didn't change any relay. But I haven't

204
00:09:32,679 --> 00:09:34,680
Speaker 6: went to the switch yet, but I do have a

205
00:09:34,760 --> 00:09:37,640
Speaker 6: question on that where you put the key in, if

206
00:09:37,640 --> 00:09:41,400
Speaker 6: that's worn a lot there in that is like, is

207
00:09:41,440 --> 00:09:43,880
Speaker 6: there like a push rod on that to that switch

208
00:09:44,320 --> 00:09:46,320
Speaker 6: that makes that contact in the switch.

209
00:09:46,480 --> 00:09:50,040
Speaker 2: Well there's yeah, there are linkages inside the column if so,

210
00:09:50,120 --> 00:09:52,640
Speaker 2: And that's why I'm saying I've seen it where the

211
00:09:52,679 --> 00:09:57,120
Speaker 2: column itself componentry inside the column whears out because it's

212
00:09:57,200 --> 00:10:01,760
Speaker 2: usually it's usually soft aluminum. It's it's not it's not

213
00:10:02,200 --> 00:10:04,520
Speaker 2: made well for lack of a better way to put it,

214
00:10:04,600 --> 00:10:09,079
Speaker 2: and that that prevents the cycle from happening. But before

215
00:10:09,160 --> 00:10:11,040
Speaker 2: we go into hey, I think it's this or I

216
00:10:11,080 --> 00:10:14,560
Speaker 2: think it's that, and linkages are worn on one hundred

217
00:10:14,600 --> 00:10:17,839
Speaker 2: and twenty thousand mile eleven year old truck. Anyway, I

218
00:10:18,440 --> 00:10:21,400
Speaker 2: vote for doing the wire test because it prevents me

219
00:10:21,480 --> 00:10:25,120
Speaker 2: from missing anything, because you could have worn linkage and

220
00:10:25,200 --> 00:10:28,680
Speaker 2: a bad ignition switch, or worn linkage and something else

221
00:10:28,720 --> 00:10:32,079
Speaker 2: going on. Right, It could be the ignition switch is great,

222
00:10:32,160 --> 00:10:33,959
Speaker 2: the linkage is worn, and the problems out under the

223
00:10:34,000 --> 00:10:35,480
Speaker 2: hood somewhere with the starter release.

224
00:10:35,679 --> 00:10:37,319
Speaker 1: You won't know until you do some testing.

225
00:10:38,520 --> 00:10:41,240
Speaker 6: Yeah, so this I'm kind of curious though, is the

226
00:10:41,320 --> 00:10:44,040
Speaker 6: key where you put the key in, if that is

227
00:10:44,200 --> 00:10:47,560
Speaker 6: worn real bad? You know, as far as the Tumblr portion,

228
00:10:48,120 --> 00:10:50,480
Speaker 6: would that would that possibly be the.

229
00:10:50,480 --> 00:10:54,840
Speaker 2: Problem if the locks if the lock cylinder turns, No,

230
00:10:55,800 --> 00:10:58,400
Speaker 2: if the lock cylinder turns, and that that applies to

231
00:10:58,480 --> 00:11:01,120
Speaker 2: anything from a sixty two Shive I Pala all the

232
00:11:01,160 --> 00:11:04,120
Speaker 2: way up to a twenty twenty five Ford pickup truck

233
00:11:04,480 --> 00:11:06,760
Speaker 2: if the lock cylinder turns, although the twenty five probably

234
00:11:06,760 --> 00:11:09,040
Speaker 2: has a push button start, but you get my point.

235
00:11:09,320 --> 00:11:11,160
Speaker 2: You know, a lock is a lock, a key is

236
00:11:11,160 --> 00:11:13,920
Speaker 2: a key. Mechanical tumblers and mechanical tumblers. We're just trying

237
00:11:13,920 --> 00:11:16,520
Speaker 2: to get the Tumblr mechanism to turn to engage the

238
00:11:16,520 --> 00:11:19,319
Speaker 2: ignition switch to allow power to pass from the green

239
00:11:19,400 --> 00:11:22,560
Speaker 2: red to the blue white wire. So that's why I

240
00:11:22,600 --> 00:11:25,800
Speaker 2: say checking that for voltage you know, let's do that.

241
00:11:26,120 --> 00:11:29,120
Speaker 2: Let's not go into analysis paralysis, Joe. Let's test something,

242
00:11:29,440 --> 00:11:32,319
Speaker 2: all right, you've got the ability, all right, kiddo.

243
00:11:33,600 --> 00:11:34,200
Speaker 3: Thanks a lot.

244
00:11:34,720 --> 00:11:36,439
Speaker 1: Ron, You're very welcome, sir. You give me a call

245
00:11:36,480 --> 00:11:38,600
Speaker 1: next week. Let me know what happens. You'd be well.

246
00:11:38,800 --> 00:11:40,719
Speaker 1: I'm running any and the Car Doctor. We're back right

247
00:11:40,720 --> 00:11:52,760
Speaker 1: after this for the best in car advice.

248
00:11:52,840 --> 00:11:55,600
Speaker 6: Give Ron a call eight five five five six zero

249
00:11:55,760 --> 00:11:58,640
Speaker 6: nine to nine zero zero. Now back to Ron.

250
00:11:58,840 --> 00:12:01,800
Speaker 2: Hey, let's get over to John and Delaware ninety three, Pontiac, Bonneville.

251
00:12:01,840 --> 00:12:02,040
Speaker 3: John.

252
00:12:02,040 --> 00:12:03,640
Speaker 1: Welcome to the Car Doctor, sir. How can I help?

253
00:12:04,760 --> 00:12:11,760
Speaker 5: Thank you very much. Yeah. I took out the compressor,

254
00:12:12,720 --> 00:12:19,600
Speaker 5: the condenser, the accumulator, cleaned out all the lines, and

255
00:12:20,200 --> 00:12:23,120
Speaker 5: put it all back together. Mike mechanic gave me some

256
00:12:24,120 --> 00:12:28,520
Speaker 5: good points, and after he evacuated and charged it, the

257
00:12:28,600 --> 00:12:32,400
Speaker 5: compressor would not engage. It hasn't engaged for even with

258
00:12:32,480 --> 00:12:38,240
Speaker 5: the old one for a while. So he doesn't know

259
00:12:38,280 --> 00:12:41,040
Speaker 5: what to do. He thinks that we could just wire

260
00:12:41,120 --> 00:12:43,160
Speaker 5: up something where you could do it manually.

261
00:12:43,679 --> 00:12:44,240
Speaker 2: I want to get it.

262
00:12:45,000 --> 00:12:48,040
Speaker 1: No, No, is this automatic ac or manually in the car?

263
00:12:50,320 --> 00:12:53,360
Speaker 5: Oh? I turned the dials myself.

264
00:12:53,480 --> 00:12:59,400
Speaker 2: Okay, all right, So so you know, listen, first things first,

265
00:12:59,600 --> 00:13:04,160
Speaker 2: all right, in the early nineties, part of the strategy

266
00:13:04,200 --> 00:13:07,640
Speaker 2: that General Motors went to was they were trying to

267
00:13:07,720 --> 00:13:09,959
Speaker 2: you know, they were tired of warranty replacements and warranty

268
00:13:10,000 --> 00:13:13,480
Speaker 2: repairs on AC compressors and so forth. So it's established

269
00:13:13,520 --> 00:13:15,120
Speaker 2: now and you can see that this is where it

270
00:13:15,120 --> 00:13:17,600
Speaker 2: came from because it affects cars today. If there are

271
00:13:17,640 --> 00:13:20,839
Speaker 2: any fault codes in the engine control module related to

272
00:13:20,880 --> 00:13:24,079
Speaker 2: air conditioning, it will not turn on the AC compressor,

273
00:13:25,800 --> 00:13:29,040
Speaker 2: all right. So I say that because it's a simple thing,

274
00:13:29,080 --> 00:13:31,080
Speaker 2: but I just want to make sure you're not overlooking something.

275
00:13:31,160 --> 00:13:33,559
Speaker 2: If there are fault codes in there, and an AC

276
00:13:33,800 --> 00:13:36,320
Speaker 2: fault code may not turn and likely will not turn

277
00:13:36,360 --> 00:13:38,960
Speaker 2: on and did not turn on a check engine light,

278
00:13:39,040 --> 00:13:41,320
Speaker 2: so you wouldn't know to go looking for a fault code.

279
00:13:41,360 --> 00:13:42,720
Speaker 2: So the first thing I'm going to tell you is,

280
00:13:43,080 --> 00:13:45,200
Speaker 2: do we have any codes in the powertrain control module?

281
00:13:45,600 --> 00:13:48,800
Speaker 1: All right? Clear them? If you clear them. If you

282
00:13:48,880 --> 00:13:50,560
Speaker 1: got any, go ahead.

283
00:13:52,520 --> 00:13:55,120
Speaker 5: I don't quite understand what you mean by clear them.

284
00:13:55,280 --> 00:13:57,720
Speaker 5: I gave it to a previous mechanic and he found

285
00:13:57,720 --> 00:14:02,079
Speaker 5: no codes. Okay, fault codes. But however, yeah, another mechanic

286
00:14:02,160 --> 00:14:04,200
Speaker 5: says he doesn't have very good equipment.

287
00:14:04,800 --> 00:14:07,040
Speaker 2: Well I went to a third right, Well, you know,

288
00:14:07,120 --> 00:14:10,679
Speaker 2: and my point is, you know, you're making chicken soup

289
00:14:10,720 --> 00:14:13,960
Speaker 2: with the neighborhood instead of just using Mom's recipe. Everybody's

290
00:14:13,960 --> 00:14:16,880
Speaker 2: got their hand in the pot. So you know, I

291
00:14:16,960 --> 00:14:18,840
Speaker 2: just want to be consistent. I want to go steps

292
00:14:18,880 --> 00:14:20,360
Speaker 2: one through five, and I want to make sure we

293
00:14:20,400 --> 00:14:24,160
Speaker 2: do all five. You know, you somebody took the AC

294
00:14:24,280 --> 00:14:27,560
Speaker 2: compressor and the condenser and everything else apart. Somebody charged it.

295
00:14:27,600 --> 00:14:30,400
Speaker 2: Somebody else did this, somebody else did that first step.

296
00:14:30,440 --> 00:14:33,080
Speaker 2: I always baseline a vehicle. I always walk up to

297
00:14:33,120 --> 00:14:35,680
Speaker 2: a patient. Where am I? What are the vitals? I'm

298
00:14:35,680 --> 00:14:38,240
Speaker 2: going to check codes every time. I don't care if

299
00:14:38,280 --> 00:14:39,840
Speaker 2: you show me the picture in the video of you

300
00:14:39,920 --> 00:14:42,120
Speaker 2: checking the codes five minutes before I got there. I'm

301
00:14:42,160 --> 00:14:45,120
Speaker 2: still checking codes. That's just the way I'm built, all right.

302
00:14:45,520 --> 00:14:47,720
Speaker 2: So you know, I want to take a scan tool

303
00:14:47,800 --> 00:14:51,040
Speaker 2: and obd one scan tool, the old stuff, the old

304
00:14:51,120 --> 00:14:53,640
Speaker 2: school style with the rectangular plug, and I want to

305
00:14:53,680 --> 00:14:56,280
Speaker 2: check for fault codes. Do I have any if there

306
00:14:56,320 --> 00:14:59,320
Speaker 2: are any codes related to air conditioning in the engine

307
00:14:59,320 --> 00:15:02,560
Speaker 2: control madch it will not turn on the AC compressor

308
00:15:03,320 --> 00:15:08,320
Speaker 2: all right. The AC relay is controlled by the powertrain

309
00:15:08,400 --> 00:15:14,280
Speaker 2: control module, meaning that you turn on the AC, the

310
00:15:14,280 --> 00:15:18,400
Speaker 2: engine controller decides, Hey, John's trying to cool off. Do

311
00:15:18,520 --> 00:15:21,480
Speaker 2: I have It's looking at two switches. It looks at

312
00:15:21,800 --> 00:15:25,000
Speaker 2: AC high pressure cutout, it looks at the pressure cycling switch,

313
00:15:25,840 --> 00:15:27,720
Speaker 2: and it looks at engine tamp. It looks at throttle

314
00:15:27,720 --> 00:15:30,160
Speaker 2: position and so forth, and decides to turn the AC on.

315
00:15:30,520 --> 00:15:33,440
Speaker 2: The engine computer actually has authority over whether or not

316
00:15:33,480 --> 00:15:35,960
Speaker 2: the AC turns on in this car, not anything else.

317
00:15:36,320 --> 00:15:37,200
Speaker 2: You get that part.

318
00:15:38,840 --> 00:15:39,720
Speaker 5: I believe that's true.

319
00:15:39,760 --> 00:15:43,040
Speaker 2: Yes, okay, So the first thing I want to do

320
00:15:44,080 --> 00:15:47,640
Speaker 2: is I want to take you got an old school

321
00:15:47,760 --> 00:15:50,360
Speaker 2: eski mechanic if he's got an old school, old style.

322
00:15:50,120 --> 00:15:53,040
Speaker 1: Headlight in the shop all right?

323
00:15:53,880 --> 00:15:55,640
Speaker 2: You know remember the days of cars when they had

324
00:15:55,720 --> 00:15:59,080
Speaker 2: round headlights or rectangular headlights, the old cel phone?

325
00:15:59,120 --> 00:16:02,160
Speaker 1: Oh yeah, yeah, right, okay, can we can?

326
00:16:02,200 --> 00:16:04,400
Speaker 2: We can? We can? We wire that headlight up to

327
00:16:04,440 --> 00:16:08,040
Speaker 2: the AC compressor, disconnect the wire at the ACQ, disconnect

328
00:16:08,080 --> 00:16:12,000
Speaker 2: the plug, put the headlight across that, turn the AC on.

329
00:16:12,040 --> 00:16:14,600
Speaker 2: Does the light come on? If the light does not

330
00:16:14,760 --> 00:16:18,840
Speaker 2: come on, all right, we've either got a bad ground

331
00:16:19,640 --> 00:16:24,240
Speaker 2: or we've got no request command to turn the AC on.

332
00:16:24,520 --> 00:16:27,400
Speaker 2: And watch what I say here. Then I want you

333
00:16:27,440 --> 00:16:30,000
Speaker 2: to go back to the scan tool and look for

334
00:16:30,400 --> 00:16:33,680
Speaker 2: an AC request. You can actually using and it didn't

335
00:16:33,720 --> 00:16:35,880
Speaker 2: take a lot back in the day. You can actually

336
00:16:35,960 --> 00:16:38,880
Speaker 2: look for an AC request on the scan tool. You

337
00:16:38,880 --> 00:16:41,320
Speaker 2: would turn the AC on. It it'll say AC request

338
00:16:41,400 --> 00:16:44,520
Speaker 2: yes or no yes, meaning that the system was capable

339
00:16:44,560 --> 00:16:48,320
Speaker 2: of recognizing the two switches I mentioned before as working,

340
00:16:49,320 --> 00:16:53,360
Speaker 2: and this PCM would then turn the AC on if

341
00:16:53,440 --> 00:16:55,600
Speaker 2: and this is important, John, this is probably the most

342
00:16:55,600 --> 00:16:57,960
Speaker 2: important thing I'm going to say to you. If you

343
00:16:58,000 --> 00:17:00,720
Speaker 2: were to look at the scan tool, it said AC

344
00:17:00,960 --> 00:17:07,000
Speaker 2: request yes, and the light doesn't light but it wants

345
00:17:07,040 --> 00:17:07,560
Speaker 2: to turn on.

346
00:17:08,760 --> 00:17:09,119
Speaker 3: All right.

347
00:17:09,440 --> 00:17:11,399
Speaker 2: I want you to go to the AC relay, the

348
00:17:11,480 --> 00:17:14,520
Speaker 2: AC compressor control relay. I want you to check for

349
00:17:14,600 --> 00:17:17,560
Speaker 2: power into the relay, all right, and the same two

350
00:17:17,640 --> 00:17:20,159
Speaker 2: power feeds feed the relay. They both come off the

351
00:17:20,200 --> 00:17:22,679
Speaker 2: same fuse as the fifteen an fuse in the relay center.

352
00:17:23,119 --> 00:17:23,600
Speaker 1: All right.

353
00:17:24,080 --> 00:17:26,399
Speaker 2: The ground leg of that relay is controlled by the

354
00:17:26,440 --> 00:17:30,760
Speaker 2: engine controller the PCM. The other leg, the power supply,

355
00:17:31,240 --> 00:17:33,840
Speaker 2: feeds down to the clutch. If you can pull that

356
00:17:33,880 --> 00:17:37,680
Speaker 2: relay out, disconnect the green black there's a light green

357
00:17:37,720 --> 00:17:39,040
Speaker 2: black trace wire that leads on.

358
00:17:39,160 --> 00:17:39,760
Speaker 5: To the PCM.

359
00:17:40,119 --> 00:17:42,560
Speaker 1: Yep, yeah, I almost know what I'm doing.

360
00:17:43,160 --> 00:17:46,919
Speaker 2: If you can disconnect that, provide an alternate ground there

361
00:17:47,760 --> 00:17:50,000
Speaker 2: and get the light to lighter the compressor to come on,

362
00:17:50,600 --> 00:17:54,399
Speaker 2: that's proving that the the PCM is not turning on

363
00:17:54,480 --> 00:17:57,680
Speaker 2: the circuit, if the switches have continuity. If that AC

364
00:17:57,840 --> 00:18:01,320
Speaker 2: request by scan tool is yes, that's a bad PCM,

365
00:18:01,800 --> 00:18:03,919
Speaker 2: flat pomp, Smack the PCM and see if you get

366
00:18:03,920 --> 00:18:05,720
Speaker 2: it to turn on. But you've got to go through

367
00:18:05,760 --> 00:18:09,040
Speaker 2: those steps to get to that point, all right. Then

368
00:18:09,080 --> 00:18:10,520
Speaker 2: the next problem is going to be can you still

369
00:18:10,520 --> 00:18:11,719
Speaker 2: buy it and see into that car.

370
00:18:12,160 --> 00:18:14,199
Speaker 1: That's a whole other story. I'm on any of the

371
00:18:14,200 --> 00:18:43,600
Speaker 1: Card doctor. I'll be back right after this. Well, welcome back.

372
00:18:43,760 --> 00:18:44,400
Speaker 1: You're still here.

373
00:18:44,440 --> 00:18:44,600
Speaker 2: Good.

374
00:18:44,600 --> 00:18:45,399
Speaker 1: I'm glad to see you here.

375
00:18:45,400 --> 00:18:47,680
Speaker 2: I'm running any of the Car Doctor, and I'm looking

376
00:18:47,720 --> 00:18:49,640
Speaker 2: forward to being with you for the next half hour.

377
00:18:50,400 --> 00:18:51,720
Speaker 2: If you got a question, give us a call a

378
00:18:51,800 --> 00:18:54,760
Speaker 2: five five, five, six zero nine nine zero zero. Otherwise

379
00:18:54,760 --> 00:18:56,920
Speaker 2: you're gonna get that sit there and I'm gonna rattle

380
00:18:56,920 --> 00:18:58,879
Speaker 2: off the top of my head. You know, it's funny

381
00:18:58,920 --> 00:19:02,200
Speaker 2: I read bulletins and bulletins to me or you know,

382
00:19:02,400 --> 00:19:04,359
Speaker 2: my family doesn't understand I haven't read a book in

383
00:19:04,400 --> 00:19:07,400
Speaker 2: twenty years because I'm always reading technical service bulletins and

384
00:19:07,800 --> 00:19:09,280
Speaker 2: I it's just my thing.

385
00:19:09,320 --> 00:19:11,479
Speaker 1: It's just it's I came across one.

386
00:19:11,560 --> 00:19:13,080
Speaker 2: You know. I got to give kudos to the guys

387
00:19:13,080 --> 00:19:16,760
Speaker 2: over at Hunter right Hunter Wheel and Service and Chassis

388
00:19:16,800 --> 00:19:22,159
Speaker 2: Service Equipment Bulletin seventeen and a one seventy Roadforce Balancer

389
00:19:22,240 --> 00:19:25,280
Speaker 2: effective February twenty seventeen. This is an older bulletin, but

390
00:19:25,280 --> 00:19:28,160
Speaker 2: I just found it this week. A generation three, four

391
00:19:28,280 --> 00:19:30,879
Speaker 2: or five Hunter road Force Bouncer is designated as essential

392
00:19:30,880 --> 00:19:33,800
Speaker 2: dealer equipment for GM dealerships. I think that's kind of neat,

393
00:19:34,119 --> 00:19:35,960
Speaker 2: you know, to have a manufacturer say, hey, you guys

394
00:19:36,000 --> 00:19:38,720
Speaker 2: make such a good product, we want you to use

395
00:19:38,760 --> 00:19:42,040
Speaker 2: one in the dealership and it's required mandatory on twenty

396
00:19:42,160 --> 00:19:45,719
Speaker 2: through twenty twenty four all GM vehicles in North America,

397
00:19:45,800 --> 00:19:47,200
Speaker 2: Argentine and so on and so forth.

398
00:19:47,240 --> 00:19:48,520
Speaker 1: So I just had to mention that I thought that

399
00:19:48,560 --> 00:19:49,320
Speaker 1: was kind of interesting.

400
00:19:49,440 --> 00:19:52,119
Speaker 2: Hey, rob My twenty sixteen F one fifty has a

401
00:19:52,240 --> 00:19:55,000
Speaker 2: V six Eco Boost engine with eighty two thousand miles

402
00:19:55,040 --> 00:19:57,840
Speaker 2: on it. It's been maintained religiously by the dealer. I've

403
00:19:57,880 --> 00:20:00,439
Speaker 2: never seen any evidence in my driveway that it's leaking coolant,

404
00:20:00,480 --> 00:20:03,119
Speaker 2: but about every two weeks the coolant level is below

405
00:20:03,119 --> 00:20:04,960
Speaker 2: the filled line. I top it off naturally, but I'm

406
00:20:04,960 --> 00:20:07,560
Speaker 2: gonna lost to what's happening to the coolant. The vehicle

407
00:20:07,600 --> 00:20:09,159
Speaker 2: runs fine and I'd like to keep it, but not

408
00:20:09,240 --> 00:20:11,399
Speaker 2: if it's got some engineering defect that's gonna leave me

409
00:20:11,440 --> 00:20:13,320
Speaker 2: on the side of the road someday. I've done some

410
00:20:13,400 --> 00:20:15,840
Speaker 2: Google searching and found that some Ego Boost engines had

411
00:20:15,880 --> 00:20:18,320
Speaker 2: similar problems, but not in the twenty sixteen V six.

412
00:20:18,359 --> 00:20:19,639
Speaker 2: What do you he thinks up with mine? Help you can

413
00:20:19,680 --> 00:20:21,240
Speaker 2: offer is greatly appreciate.

414
00:20:20,760 --> 00:20:21,840
Speaker 1: It, Dan.

415
00:20:22,320 --> 00:20:25,240
Speaker 2: You know, Dan, I have seen more than a few

416
00:20:25,280 --> 00:20:29,679
Speaker 2: of these suffer from coolant leaks in and around the

417
00:20:29,720 --> 00:20:32,600
Speaker 2: coolant tubes, the lines that lead up to the turbo assembly.

418
00:20:33,119 --> 00:20:36,080
Speaker 2: And it's it's a hard to see leak because it happens.

419
00:20:36,800 --> 00:20:39,760
Speaker 2: It happens while you're driving, and it'll hit the exhaust

420
00:20:40,000 --> 00:20:43,640
Speaker 2: and it steam rattles off. So you know, the drop

421
00:20:43,640 --> 00:20:47,080
Speaker 2: of coolant hits the hot exhaust and it just disappears

422
00:20:47,119 --> 00:20:49,280
Speaker 2: and evaporates, and you don't know where it's coming from.

423
00:20:49,680 --> 00:20:51,159
Speaker 2: And then all of a sudden you stop and you

424
00:20:51,240 --> 00:20:53,840
Speaker 2: check a week or two later, and you're low on coolant.

425
00:20:54,359 --> 00:20:56,919
Speaker 2: So I would tell you to add a die to

426
00:20:56,960 --> 00:20:59,159
Speaker 2: the cooling system like it would for any other coolant

427
00:20:59,200 --> 00:21:02,560
Speaker 2: leak and verify. You know what do I see? Do

428
00:21:02,640 --> 00:21:05,720
Speaker 2: I see cooling stains and around the cooler lines leading

429
00:21:05,800 --> 00:21:07,639
Speaker 2: up to the turbocharger unit. And if you do, you

430
00:21:07,680 --> 00:21:08,960
Speaker 2: know where you've got to go. You know what the

431
00:21:09,000 --> 00:21:13,359
Speaker 2: repair is. I guess that's an engineering defect in a sense,

432
00:21:13,440 --> 00:21:16,440
Speaker 2: but you know it's common on these you know, turbot

433
00:21:16,520 --> 00:21:19,879
Speaker 2: chargers in general, in my opinion, require more maintenance. They

434
00:21:20,560 --> 00:21:23,320
Speaker 2: they do have some good to them. They do provide

435
00:21:23,320 --> 00:21:26,119
Speaker 2: a great deal more power from a smaller engine, but

436
00:21:26,440 --> 00:21:28,639
Speaker 2: I think that power comes at a price, you know,

437
00:21:28,760 --> 00:21:31,800
Speaker 2: more wear and tear. You're making the smaller horse pull

438
00:21:31,840 --> 00:21:35,359
Speaker 2: the bigger trailer. You know, all the time, it's working

439
00:21:35,400 --> 00:21:37,400
Speaker 2: harder to do it. So it just requires a little

440
00:21:37,400 --> 00:21:40,400
Speaker 2: bit more maintenance, a little bit more forethought, definitely more

441
00:21:40,400 --> 00:21:42,719
Speaker 2: oil changes, athle It's not related to your question. So,

442
00:21:43,080 --> 00:21:45,440
Speaker 2: but take a look at those cooler lines. If you

443
00:21:45,560 --> 00:21:48,320
Speaker 2: find that the cooler lines are dry, if you're convinced

444
00:21:48,320 --> 00:21:51,840
Speaker 2: this is not a turbocharger cooland line related issue and

445
00:21:52,000 --> 00:21:54,320
Speaker 2: you don't see leaks anywhere else, I'm going to go

446
00:21:54,359 --> 00:21:56,760
Speaker 2: to my old standby to see if it does it

447
00:21:56,880 --> 00:21:58,480
Speaker 2: for you, and it should. Take a look at k

448
00:21:58,640 --> 00:22:00,000
Speaker 2: sealkseal dot com.

449
00:22:00,440 --> 00:22:01,080
Speaker 1: K seal.

450
00:22:01,320 --> 00:22:03,679
Speaker 2: They also make it in k seal Ultimate, which is

451
00:22:03,760 --> 00:22:07,160
Speaker 2: if you suspect this is a head gasket issue, case

452
00:22:07,160 --> 00:22:10,560
Speaker 2: seal will help to seal a seeping head gasket. It

453
00:22:10,680 --> 00:22:12,760
Speaker 2: is a double dose of k seal in the bottle.

454
00:22:12,800 --> 00:22:17,040
Speaker 2: It's it's it's a more dense charge or a denser

455
00:22:17,119 --> 00:22:21,040
Speaker 2: amount of k seal sealer, you know on a vehicle's

456
00:22:21,080 --> 00:22:23,520
Speaker 2: you know, I say older. Everybody's gonna laugh, but you

457
00:22:23,520 --> 00:22:26,160
Speaker 2: know there's is sixteen. This truck's already eight years old

458
00:22:26,800 --> 00:22:28,720
Speaker 2: with eighty two thousand miles on it. So, you know,

459
00:22:28,880 --> 00:22:32,399
Speaker 2: is it economically viable to pull it apart? You know,

460
00:22:32,400 --> 00:22:33,800
Speaker 2: if I can do it with a bottle of case

461
00:22:33,800 --> 00:22:35,840
Speaker 2: seal and make it and it's still reliable and the

462
00:22:36,040 --> 00:22:39,040
Speaker 2: coolant luss goes away, you know, in my eyes. Yeah,

463
00:22:39,080 --> 00:22:41,160
Speaker 2: that kind of works because right now it's a matter

464
00:22:41,200 --> 00:22:44,200
Speaker 2: of economics. It's a tough economy out there, and obviously

465
00:22:44,200 --> 00:22:47,440
Speaker 2: you can find more information at the k seal dot com.

466
00:22:47,520 --> 00:22:50,680
Speaker 2: Another letter, Dave writes in, Hey, Ron, I'm a long

467
00:22:50,720 --> 00:22:52,800
Speaker 2: time listener. My father and I used to always listen

468
00:22:52,880 --> 00:22:54,440
Speaker 2: to you in the car when traveling up and down

469
00:22:54,440 --> 00:22:56,720
Speaker 2: the Garden State Parkway. I still listen on a regular basis.

470
00:22:56,760 --> 00:22:58,960
Speaker 2: I guess Dave moved. You know, I got to tell

471
00:22:59,000 --> 00:23:02,200
Speaker 2: you the my dad and I stuff, or my mom

472
00:23:02,240 --> 00:23:06,320
Speaker 2: and I stuff. It just, you know what, that just

473
00:23:06,400 --> 00:23:08,240
Speaker 2: kind of puts a smile on my face. It's nice to,

474
00:23:08,760 --> 00:23:10,879
Speaker 2: you know, know that this radio show has a purpose.

475
00:23:10,920 --> 00:23:14,359
Speaker 2: It gives me a sense of purpose. I enjoy it,

476
00:23:14,400 --> 00:23:17,400
Speaker 2: I really do. I had, as an aside to Dave's comments,

477
00:23:17,440 --> 00:23:20,360
Speaker 2: I had a longtime listener, Jeff tell me this week

478
00:23:20,400 --> 00:23:23,879
Speaker 2: his mom had just passed and I was exchanging condolences

479
00:23:23,880 --> 00:23:25,760
Speaker 2: with him, and he said, you know, Ron, I felt

480
00:23:25,800 --> 00:23:27,960
Speaker 2: the most comfortable when I sat there listening to the show,

481
00:23:28,040 --> 00:23:31,399
Speaker 2: because it reminded me of sitting there like Mom was

482
00:23:31,480 --> 00:23:33,639
Speaker 2: right beside me. And you know what, I got to

483
00:23:33,680 --> 00:23:36,359
Speaker 2: tell you, it's not about doing radio, and it's not

484
00:23:36,440 --> 00:23:39,360
Speaker 2: about fixing cars. It's about helping people feel better and

485
00:23:39,560 --> 00:23:40,960
Speaker 2: get through the day. And I was glad to do

486
00:23:41,000 --> 00:23:42,520
Speaker 2: it for you, Jeff, and I'm glad to do it for.

487
00:23:42,520 --> 00:23:42,840
Speaker 3: All of you.

488
00:23:43,200 --> 00:23:45,119
Speaker 2: Anyway, back to Dave Ron, I've got a twenty nineteen

489
00:23:45,200 --> 00:23:47,600
Speaker 2: Chevy Suburban with a six point two liter V eight.

490
00:23:47,640 --> 00:23:49,159
Speaker 2: It was a special order, I would think, so they

491
00:23:49,160 --> 00:23:51,320
Speaker 2: didn't put out a lot of V eight's. The truck's

492
00:23:51,320 --> 00:23:53,119
Speaker 2: been great. Over the last six months, I've had an

493
00:23:53,119 --> 00:23:55,840
Speaker 2: intermittent electrical issue. The truck will occasionally go into limp

494
00:23:55,840 --> 00:23:59,359
Speaker 2: mode and throw a code for brottle pedal position, sensor

495
00:23:59,480 --> 00:24:02,439
Speaker 2: voltage CORE. I've changed both the electric throttle body and

496
00:24:02,480 --> 00:24:05,280
Speaker 2: the electric gas pedal, both of them GM genuine replacements.

497
00:24:05,520 --> 00:24:06,920
Speaker 2: Do you have any tips on where to go next?

498
00:24:06,960 --> 00:24:09,400
Speaker 2: The problem may happen three times a week or once

499
00:24:09,440 --> 00:24:11,360
Speaker 2: a month, it varies. It usually happens if the car

500
00:24:11,400 --> 00:24:13,560
Speaker 2: has been driven on the highway for a while and

501
00:24:13,600 --> 00:24:15,600
Speaker 2: then you get off and start doing slower speeds. It's

502
00:24:15,600 --> 00:24:17,919
Speaker 2: also happened a couple of times while sitting still and

503
00:24:17,960 --> 00:24:19,840
Speaker 2: not even pressing the gas pedal with the vehicle in

504
00:24:19,920 --> 00:24:21,639
Speaker 2: park and the advice you could be great. I basically

505
00:24:21,680 --> 00:24:23,560
Speaker 2: go to mode of knowledge, but I am not trained

506
00:24:23,560 --> 00:24:25,080
Speaker 2: in any matter. At one point I did look at

507
00:24:25,119 --> 00:24:26,639
Speaker 2: livedet on a scan tool and the vultage of the

508
00:24:26,680 --> 00:24:29,080
Speaker 2: pedal was different than the voltage of the throttle body.

509
00:24:29,080 --> 00:24:30,639
Speaker 2: I'm just not sure how it would change going from

510
00:24:30,680 --> 00:24:33,040
Speaker 2: pedal to the throttle body, whereas that middle point does

511
00:24:33,040 --> 00:24:35,359
Speaker 2: a path through a computer a module. Any help you

512
00:24:35,359 --> 00:24:36,480
Speaker 2: can give us greatly appreciated.

513
00:24:36,560 --> 00:24:37,200
Speaker 1: Dave Drobney.

514
00:24:37,720 --> 00:24:42,480
Speaker 2: Dave, there's actually some known issues with this particular problem.

515
00:24:42,560 --> 00:24:46,560
Speaker 2: There are several connectors connector X fifteen connector X nineteen

516
00:24:47,720 --> 00:24:50,280
Speaker 2: ones located near the fuse block. They're actually both located

517
00:24:50,280 --> 00:24:52,600
Speaker 2: near the fuse block, and you've got to go through

518
00:24:53,000 --> 00:24:56,440
Speaker 2: fuse box connectors out under the hood, and I'm sorry,

519
00:24:56,520 --> 00:24:58,840
Speaker 2: nineteen one to nineteen is in the left side of

520
00:24:58,840 --> 00:25:01,560
Speaker 2: the instrument panel, so there have been some wiring issues.

521
00:25:01,920 --> 00:25:04,320
Speaker 2: You can get out a wiring diagram and look to

522
00:25:04,359 --> 00:25:06,760
Speaker 2: see if you follow it, it will go from the

523
00:25:06,800 --> 00:25:10,240
Speaker 2: throttle pedal position sensor assembly out through the throttle body

524
00:25:10,240 --> 00:25:13,560
Speaker 2: and then interconnect with the main engine PCM. We have

525
00:25:13,720 --> 00:25:16,560
Speaker 2: had a few of these where we've actually made a harness.

526
00:25:16,760 --> 00:25:18,879
Speaker 2: We've gone right. You know, We've gotten a connector at

527
00:25:18,920 --> 00:25:22,800
Speaker 2: the throttle pedal position assembly, gotten a connector for the

528
00:25:22,840 --> 00:25:26,399
Speaker 2: throttle body, and made wiring in between. And that solves

529
00:25:26,400 --> 00:25:29,280
Speaker 2: that they do have some connector and wiring issues here.

530
00:25:29,359 --> 00:25:31,480
Speaker 2: So you know, I would start looking at those two

531
00:25:31,520 --> 00:25:34,199
Speaker 2: connectors X fifteen out at the fuse block under the

532
00:25:34,200 --> 00:25:37,000
Speaker 2: hood and X nineteen. You are going to need a

533
00:25:37,000 --> 00:25:40,240
Speaker 2: good wiring diagram. This is not something to attack without

534
00:25:40,280 --> 00:25:43,320
Speaker 2: and form a strategy. This is one of those repairs

535
00:25:43,320 --> 00:25:45,960
Speaker 2: that in order to understand the circuitry, I would print

536
00:25:46,000 --> 00:25:49,040
Speaker 2: out the wiring diagram and I would sit down with

537
00:25:49,080 --> 00:25:51,720
Speaker 2: some colored markers and start labeling things. This has to

538
00:25:51,720 --> 00:25:53,760
Speaker 2: go here, this has to go there, and it has

539
00:25:53,760 --> 00:25:55,399
Speaker 2: to be quiet when you do this. Nobody can be

540
00:25:55,440 --> 00:25:57,480
Speaker 2: talking to you because it's easy to make mistakes and

541
00:25:57,520 --> 00:26:00,359
Speaker 2: start tracing out your wiring and connections and evolve looks good.

542
00:26:00,720 --> 00:26:02,520
Speaker 2: Run six new wires and I think you're going to

543
00:26:02,600 --> 00:26:05,520
Speaker 2: find you solve the problem. But it just takes a

544
00:26:05,520 --> 00:26:08,280
Speaker 2: little time. It is doable, it is repairable. It's just

545
00:26:08,320 --> 00:26:10,840
Speaker 2: going to take some effort on your parts or so,

546
00:26:11,080 --> 00:26:13,000
Speaker 2: if you have any questions, give me a call. If

547
00:26:13,000 --> 00:26:16,720
Speaker 2: you're looking for a wiring diagram information. Here's a great

548
00:26:16,880 --> 00:26:19,720
Speaker 2: reason to go out to All Data All Data dot Com.

549
00:26:19,800 --> 00:26:23,639

550
00:26:23,720 --> 00:26:26,640
Speaker 2: They will give you factory wiring diagram. I think it's

551
00:26:26,680 --> 00:26:29,360
Speaker 2: All Data DIY dot com or DIY All Data dot Com.

552
00:26:29,359 --> 00:26:30,920
Speaker 2: I forget which way it goes, but if you google

553
00:26:30,920 --> 00:26:34,560
Speaker 2: it you'll find it. Their DIY subscriptions are affordable and

554
00:26:34,960 --> 00:26:37,359
Speaker 2: they will help you too, you know, with wiring diagrams.

555
00:26:37,480 --> 00:26:40,800
Speaker 2: Same information and repair shop seas for that specific vehicle.

556
00:26:40,800 --> 00:26:42,879
Speaker 2: And if you're planning on keeping the vehicle for any

557
00:26:42,960 --> 00:26:46,320
Speaker 2: length of time, it's it's just as important as putting

558
00:26:46,359 --> 00:26:48,119
Speaker 2: gas in the tank and good oil in the engine.

559
00:26:48,280 --> 00:26:51,920
Speaker 2: You need information to fix things. So do that a

560
00:26:52,040 --> 00:26:54,400
Speaker 2: five five, five, six zero nine nine zero zero mornin

561
00:26:54,400 --> 00:26:55,080
Speaker 2: any of the car doctor.

562
00:26:55,080 --> 00:26:56,120
Speaker 1: I'll be back right after this.

563
00:27:08,640 --> 00:27:11,199
Speaker 2: All right, Tom, sit down, Tom, no more dancing, and

564
00:27:11,240 --> 00:27:12,280
Speaker 2: I'll put your clothes back on.

565
00:27:12,480 --> 00:27:14,640
Speaker 1: Let's go over to uh. Hey, you're the one who

566
00:27:14,680 --> 00:27:15,640
Speaker 1: lended me the white suit.

567
00:27:16,160 --> 00:27:18,439
Speaker 2: It had to come from somewhere, brother. I think I

568
00:27:18,480 --> 00:27:19,920
Speaker 2: still have my white suit, you know. Every once in

569
00:27:19,960 --> 00:27:22,040
Speaker 2: a while, here in New Jersey out on Route eighty.

570
00:27:22,080 --> 00:27:24,600
Speaker 2: We go past the soap factory in Richfield Park, and

571
00:27:24,640 --> 00:27:27,760
Speaker 2: I still think about those disco days in the seventies.

572
00:27:27,280 --> 00:27:29,320
Speaker 6: But no reason on it.

573
00:27:29,400 --> 00:27:31,600
Speaker 2: Yeah, I'm just oh my gosh, it was like, you know,

574
00:27:31,720 --> 00:27:35,160
Speaker 2: holy count it really was like Saturday. My kids laugh

575
00:27:35,200 --> 00:27:37,000
Speaker 2: at me, but it really was like Saturday night fever

576
00:27:37,040 --> 00:27:39,080
Speaker 2: with the disco ball and the lights.

577
00:27:39,119 --> 00:27:40,960
Speaker 1: And they were like, what was that all about that?

578
00:27:41,080 --> 00:27:43,000
Speaker 2: I said, I don't know it was. You know, we

579
00:27:43,000 --> 00:27:45,399
Speaker 2: were all upset that the Golden era had changed. So

580
00:27:45,560 --> 00:27:48,520
Speaker 2: let's go over to Richard in Texas twelve Escape and

581
00:27:48,760 --> 00:27:49,560
Speaker 2: see what's going on here.

582
00:27:49,640 --> 00:27:53,320
Speaker 1: Richard. Welcome to the car doctor, sir. How can I help, Yes.

583
00:27:53,200 --> 00:27:57,840
Speaker 3: Sir, Yeah, it's a twenty twelve four to Escape. I

584
00:27:57,840 --> 00:27:59,840
Speaker 3: I've had the issue one even when I bought it,

585
00:28:00,040 --> 00:28:02,800
Speaker 3: and I've already put a throttle body on.

586
00:28:02,880 --> 00:28:03,840
Speaker 1: End, okay.

587
00:28:04,000 --> 00:28:07,359
Speaker 3: And what it is is that whenever I put it

588
00:28:07,400 --> 00:28:10,600
Speaker 3: in reverse at the very start, you know, when you

589
00:28:10,640 --> 00:28:14,760
Speaker 3: first get in the morning, I started, and then I

590
00:28:14,800 --> 00:28:18,160
Speaker 3: put it in reverse and the idol just jumps up

591
00:28:18,320 --> 00:28:22,679
Speaker 3: very high, and then I don't have any breaks.

592
00:28:23,640 --> 00:28:28,520
Speaker 2: So you're saying the idle speed flares up over two grand.

593
00:28:28,400 --> 00:28:30,400
Speaker 3: As soon as you get as soon as you put

594
00:28:30,400 --> 00:28:33,960
Speaker 3: it in reverse, it just it shoots up. The aisle

595
00:28:34,080 --> 00:28:36,919
Speaker 3: shoots up very high. And then if I take it

596
00:28:37,000 --> 00:28:40,520
Speaker 3: out of reverse and put it into drive, it's normal.

597
00:28:40,800 --> 00:28:44,640
Speaker 3: And then if I put it back into reverse, it's normal.

598
00:28:45,600 --> 00:28:48,920
Speaker 3: Now it doesn't do that all the time, but sometimes

599
00:28:48,920 --> 00:28:50,600
Speaker 3: I have to do it two or three times in

600
00:28:50,640 --> 00:28:54,000
Speaker 3: the drive to get it to go back to normal

601
00:28:54,120 --> 00:28:59,120
Speaker 3: and reverse. Now, once that's happened, it's okay. After that,

602
00:28:59,320 --> 00:29:02,240
Speaker 3: I have no wish you throughout the whole day. Okay,

603
00:29:02,240 --> 00:29:04,520
Speaker 3: it's just the first time when you first started.

604
00:29:05,720 --> 00:29:07,800
Speaker 2: One of the things I want to know is, so

605
00:29:08,040 --> 00:29:10,479
Speaker 2: let's let's talk about this. Let's let's talk about the

606
00:29:10,520 --> 00:29:13,160
Speaker 2: far side of this as a as a potential repair.

607
00:29:13,640 --> 00:29:15,760
Speaker 2: You know, when I hear things like this, I start

608
00:29:15,760 --> 00:29:17,640
Speaker 2: to think, do I have and I'm just saying you do,

609
00:29:17,760 --> 00:29:20,480
Speaker 2: We're just chatting, right, I start to think, do I

610
00:29:20,720 --> 00:29:25,160
Speaker 2: have an engine with a bad transunt motor mount something

611
00:29:25,200 --> 00:29:27,840
Speaker 2: that's allowing the drive train to move and pull on

612
00:29:27,880 --> 00:29:31,000
Speaker 2: the wiring harness in the wrong direction, and it has

613
00:29:31,040 --> 00:29:33,840
Speaker 2: it done it over time and caused the wiring harness

614
00:29:33,840 --> 00:29:38,080
Speaker 2: to break broken, poor connection, poor contact, et cetera. Just

615
00:29:38,200 --> 00:29:40,680
Speaker 2: and it's an easy quick thing to look at. Go ahead,

616
00:29:40,720 --> 00:29:43,520
Speaker 2: you're going to say, well.

617
00:29:44,120 --> 00:29:48,000
Speaker 3: In the beginning, though, I did replace the right motor

618
00:29:48,320 --> 00:29:51,240
Speaker 3: on the passenger side, okay, because I could tell that

619
00:29:51,280 --> 00:29:53,920
Speaker 3: one had a vibration. As soon as I replace that,

620
00:29:54,280 --> 00:29:56,280
Speaker 3: the thing was running very smooth.

621
00:29:56,040 --> 00:29:56,440
Speaker 1: All right.

622
00:29:57,040 --> 00:30:02,360
Speaker 2: So you know, again testing the harness, trying to duplicate,

623
00:30:02,400 --> 00:30:04,160
Speaker 2: trying to get it to act up, not a bad

624
00:30:04,200 --> 00:30:07,040
Speaker 2: way to go. What I think about from your description

625
00:30:07,400 --> 00:30:11,920
Speaker 2: is this sounds without any testing. This sounds like a

626
00:30:12,040 --> 00:30:15,760
Speaker 2: computer control issue, like the computer is taking over.

627
00:30:16,280 --> 00:30:17,440
Speaker 1: I would be curious.

628
00:30:17,840 --> 00:30:20,560
Speaker 2: So you know, my question is is it the physical

629
00:30:20,600 --> 00:30:23,720
Speaker 2: movement of putting the car in reverse? Does the transmission

630
00:30:23,760 --> 00:30:26,080
Speaker 2: have to be in reverse? Or if I were to

631
00:30:26,200 --> 00:30:30,479
Speaker 2: just disconnect the switch off the trends and manually cycle

632
00:30:30,520 --> 00:30:33,440
Speaker 2: it into reverse in the bay vehicles in park, but

633
00:30:33,520 --> 00:30:36,080
Speaker 2: I put it in reverse, the switch shows reverse to

634
00:30:36,120 --> 00:30:39,800
Speaker 2: the PCM. Does the PCM start to automatically raise the

635
00:30:39,840 --> 00:30:43,640
Speaker 2: idle speed all right? Because it will It will alter

636
00:30:43,760 --> 00:30:47,280
Speaker 2: idle strategy, you know, from reverse to drive and so forth.

637
00:30:47,320 --> 00:30:49,800
Speaker 2: So do I have an idle strategy issue going on?

638
00:30:50,160 --> 00:30:52,640
Speaker 2: Do I have a ground problem at the PCM that

639
00:30:52,720 --> 00:30:55,000
Speaker 2: it can't react. You know, when I get a car

640
00:30:55,080 --> 00:30:57,040
Speaker 2: that acts weird like this, and I've gone through the

641
00:30:57,040 --> 00:31:00,720
Speaker 2: basics and the inputs and the outputs and the test,

642
00:31:01,480 --> 00:31:02,640
Speaker 2: I try to narrow it down.

643
00:31:02,720 --> 00:31:03,760
Speaker 1: Do I have a bad computer?

644
00:31:04,000 --> 00:31:06,560
Speaker 2: Do I have a computer that's acting up randomly on

645
00:31:06,640 --> 00:31:10,200
Speaker 2: its own, showing me like the Microsoft Windows Blue screen

646
00:31:10,240 --> 00:31:13,080
Speaker 2: of death whenever it wants to, and then it goes

647
00:31:13,160 --> 00:31:17,720
Speaker 2: away the fact that you cycle through the gears and

648
00:31:18,160 --> 00:31:21,880
Speaker 2: then it's normal. It kind of gets it out of

649
00:31:21,880 --> 00:31:25,040
Speaker 2: its system. It's acting erratically like that. But I've got

650
00:31:25,040 --> 00:31:26,680
Speaker 2: to go through some testing first. I've got to go

651
00:31:26,720 --> 00:31:29,120
Speaker 2: through switches. I've got to go through grounds. I've got

652
00:31:29,120 --> 00:31:31,520
Speaker 2: to go through you know, I'm gonna say this the

653
00:31:31,520 --> 00:31:36,440
Speaker 2: basic things, battery, terminal connections, things like that. And I

654
00:31:36,480 --> 00:31:38,840
Speaker 2: say this from experience. I had a Ford fusion. This

655
00:31:38,880 --> 00:31:41,000
Speaker 2: is a four Cylinder's a four cylinder, isn't it, Richard?

656
00:31:42,320 --> 00:31:44,000
Speaker 1: No, it's a V six.

657
00:31:44,200 --> 00:31:48,560
Speaker 2: Okay, I would start to approach it. Well'll tell you what,

658
00:31:48,640 --> 00:31:51,240
Speaker 2: Sit tight, Sit tight real fast. Let me I'm gonna

659
00:31:51,240 --> 00:31:52,640
Speaker 2: have to do two for one when I get back,

660
00:31:52,840 --> 00:31:54,400
Speaker 2: But let me pull over and take this poison. When

661
00:31:54,400 --> 00:31:56,000
Speaker 2: I come back, we're gonna knock two out of the gate.

662
00:31:56,040 --> 00:31:58,200
Speaker 2: I'm running ending the car. Doctor will return right after this.

663
00:32:04,480 --> 00:32:05,120
Speaker 2: She's real.

664
00:32:05,240 --> 00:32:10,760
Speaker 1: Find my four nice, she's real, find my fine, my faut.

665
00:32:15,240 --> 00:32:17,200
Speaker 2: Okay, here we go, two for a nickel running in

666
00:32:17,360 --> 00:32:23,080
Speaker 2: the car doctor, Richard Texas. One last question, real quick, Okay,

667
00:32:23,680 --> 00:32:25,760
Speaker 2: you had a question. You had a comment before the break.

668
00:32:27,080 --> 00:32:31,000
Speaker 3: Well, yeah, I was gonna say somebody had mentioned a

669
00:32:31,120 --> 00:32:32,280
Speaker 3: temperature sensor.

670
00:32:33,200 --> 00:32:35,720
Speaker 2: Well, there's a there's an air intake, there's there's there's

671
00:32:35,760 --> 00:32:39,080
Speaker 2: an ambient temp sensor and an engine temperature sensor. That's

672
00:32:39,080 --> 00:32:45,320
Speaker 2: how it knows it's cold or hot depending upon Sorry, yeah.

673
00:32:44,080 --> 00:32:46,239
Speaker 3: You know, I just did that have any effect on

674
00:32:46,320 --> 00:32:47,320
Speaker 3: that with the computer?

675
00:32:47,640 --> 00:32:52,280
Speaker 2: Well, engine temperature and ambient temperature will affect whether or

676
00:32:52,360 --> 00:32:55,400
Speaker 2: not it raises idle speed, but it won't matter whether

677
00:32:55,480 --> 00:32:58,440
Speaker 2: or not it's in reverse or forward. So I don't

678
00:32:58,480 --> 00:33:01,000
Speaker 2: I don't think that's really got any input. You could

679
00:33:01,000 --> 00:33:04,080
Speaker 2: try an experiment. You could unplug the tempt sensor, which

680
00:33:04,120 --> 00:33:07,080
Speaker 2: will radically change the temperature profile and see what it does.

681
00:33:07,360 --> 00:33:09,080
Speaker 2: But you're also going to put a code in the system,

682
00:33:09,120 --> 00:33:11,440
Speaker 2: so be careful what you do. But I think what

683
00:33:11,480 --> 00:33:13,720
Speaker 2: you've really got to look at here is, like I said,

684
00:33:13,800 --> 00:33:17,000
Speaker 2: eliminate the possibility of it being a mount issue pulling

685
00:33:17,040 --> 00:33:18,480
Speaker 2: on the harness. I don't think it is, but let's

686
00:33:18,520 --> 00:33:21,840
Speaker 2: eliminate it all right. Let's eliminate good powers and grounds

687
00:33:21,880 --> 00:33:24,840
Speaker 2: going into the PCM. Let's make sure we've got proper input.

688
00:33:24,880 --> 00:33:27,760
Speaker 2: And I think, unfortunately for you, at that point, if

689
00:33:27,800 --> 00:33:30,280
Speaker 2: all else has been considered, you've got to take a

690
00:33:30,320 --> 00:33:34,320
Speaker 2: look at and consider possibly swapping a PCM. I have

691
00:33:34,400 --> 00:33:38,240
Speaker 2: seen PCMs with their own personalities be difficult like that,

692
00:33:38,680 --> 00:33:41,640
Speaker 2: and you know, possibly be a solution for it. So

693
00:33:41,800 --> 00:33:43,640
Speaker 2: more time to talk next week. If you need me, Richard,

694
00:33:43,640 --> 00:33:45,360
Speaker 2: give me a shout, Billy and Maine Billy.

695
00:33:45,360 --> 00:33:47,120
Speaker 1: What's going on? What can I do for you? Real quick?

696
00:33:47,280 --> 00:33:47,680
Speaker 2: Thank god?

697
00:33:47,760 --> 00:33:51,040
Speaker 1: Doctor. I got a sci on XB and when I

698
00:33:51,080 --> 00:33:54,560
Speaker 1: put it in reverse recently, it makes a click. Okay,

699
00:33:56,320 --> 00:34:00,160
Speaker 1: one singular click with the vehicle not moving. Is it is?

700
00:34:00,320 --> 00:34:00,400
Speaker 2: No?

701
00:34:01,240 --> 00:34:02,840
Speaker 3: When I put it in like when I put it

702
00:34:02,840 --> 00:34:05,160
Speaker 3: in reverse and and give it the gas.

703
00:34:05,920 --> 00:34:06,880
Speaker 6: Uh, it does it?

704
00:34:06,880 --> 00:34:09,080
Speaker 3: Does it when I It doesn't do it any other time,

705
00:34:09,239 --> 00:34:11,120
Speaker 3: just that, just when I put it in reverse like that.

706
00:34:11,200 --> 00:34:13,799
Speaker 2: So as you're backing up, or just the moment of

707
00:34:14,280 --> 00:34:15,280
Speaker 2: putting it in reverse.

708
00:34:15,440 --> 00:34:18,280
Speaker 6: In other words, the moment of putting it in the reverse.

709
00:34:18,400 --> 00:34:22,040
Speaker 2: But once it's moving, it doesn't make the sound. No, okay,

710
00:34:22,239 --> 00:34:24,719
Speaker 2: So we're going to talk about engine mounts. We're going

711
00:34:24,760 --> 00:34:26,880
Speaker 2: to talk about a cradle issue. You're up in Maine.

712
00:34:27,000 --> 00:34:29,560
Speaker 2: What's the salt content and the rust and corrosion factor?

713
00:34:30,000 --> 00:34:32,000
Speaker 2: Can you replicate it every time? If you put it

714
00:34:32,040 --> 00:34:33,800
Speaker 2: back in park and then go to put it in reverse,

715
00:34:33,840 --> 00:34:34,640
Speaker 2: does it do it again?

716
00:34:36,960 --> 00:34:40,200
Speaker 3: I not always, but a lot.

717
00:34:40,480 --> 00:34:44,800
Speaker 2: Try this, okay, get it to happen. Click in reverse,

718
00:34:45,280 --> 00:34:49,000
Speaker 2: put the engine in drive. All right, power break it.

719
00:34:49,080 --> 00:34:51,000
Speaker 2: One foot on the brake, one foot on the gas.

720
00:34:51,040 --> 00:34:54,880
Speaker 2: Load the engine in the drive train in the other direction. Okay,

721
00:34:55,440 --> 00:34:58,560
Speaker 2: let it settle. Put it back in park, put it

722
00:34:58,560 --> 00:35:00,719
Speaker 2: in reverse. Does it make the noise again? If you

723
00:35:00,760 --> 00:35:02,600
Speaker 2: can power break it back and forth and get it

724
00:35:02,600 --> 00:35:05,200
Speaker 2: to happen, you're looking at a mount or of frame issue.

725
00:35:05,239 --> 00:35:07,440
Speaker 2: Something's shifting, and that'll at least give you a direction.

726
00:35:07,719 --> 00:35:09,640
Speaker 2: If you need more, call me next week. I'm running

727
00:35:09,680 --> 00:35:11,839
Speaker 2: ending in the car doctor reminding all of you, good

728
00:35:11,840 --> 00:35:13,160
Speaker 2: mechanics aren't expensive.

729
00:35:13,200 --> 00:35:14,480
Speaker 1: They're priceless, See you
