1 00:00:03,760 --> 00:00:06,040 Speaker 1: Ron An Aian. There's got to be consistency in order 2 00:00:06,040 --> 00:00:10,799 Speaker 1: to repair. Also, you know most things can be predicted three, six, eight, 3 00:00:10,880 --> 00:00:12,800 Speaker 1: ten months in advance. Hey, we know you're gonna need 4 00:00:12,880 --> 00:00:15,160 Speaker 1: tires next year. We know you're gonna need breaks next year. 5 00:00:15,600 --> 00:00:18,279 Speaker 1: The opnator that drops that on Tuesday, Yeah, nobody could 6 00:00:18,280 --> 00:00:18,960 Speaker 1: predict that. 7 00:00:19,040 --> 00:00:19,360 Speaker 2: Is not. 8 00:00:21,960 --> 00:00:31,720 Speaker 1: Staking bus driver scene. See the car Doctor. 9 00:00:31,880 --> 00:00:34,120 Speaker 3: It's been like in a high fifties sixties. 10 00:00:34,320 --> 00:00:35,760 Speaker 2: I said, you don't you feel it cold? 11 00:00:35,760 --> 00:00:36,960 Speaker 4: But you can't really gauze. 12 00:00:37,080 --> 00:00:41,080 Speaker 1: Right, it's not enough. There's no heat load on the system. 13 00:00:41,200 --> 00:00:41,320 Speaker 2: Right. 14 00:00:41,520 --> 00:00:44,479 Speaker 5: Welcome to the radio home of ron An Aian, the 15 00:00:44,520 --> 00:00:45,159 Speaker 5: Car Doctor. 16 00:00:45,440 --> 00:00:46,760 Speaker 1: Since nineteen ninety one. 17 00:00:46,920 --> 00:00:50,080 Speaker 5: This is where car owners the world overturned to for 18 00:00:50,240 --> 00:00:54,560 Speaker 5: their definitive opinion on automotive repair. If your mechanics giving 19 00:00:54,600 --> 00:00:57,440 Speaker 5: you a busy signal, pick up the phone and call in. 20 00:00:57,920 --> 00:01:00,680 Speaker 1: The garage doors are open. I am here to take 21 00:01:00,720 --> 00:01:03,960 Speaker 1: your calls at eight five five, five six hundred and 22 00:01:04,040 --> 00:01:10,600 Speaker 1: now running well, we get another week of challenging motor 23 00:01:10,600 --> 00:01:13,039 Speaker 1: repair questions at eight five five five six zero nine 24 00:01:13,120 --> 00:01:14,959 Speaker 1: nine zero zero. But that's okay. I'm here to work 25 00:01:15,000 --> 00:01:17,440 Speaker 1: and get started. So let's dive right into a dan 26 00:01:17,520 --> 00:01:19,920 Speaker 1: in Connecticut waiting nevery patiently, sir, how can I help 27 00:01:19,920 --> 00:01:21,400 Speaker 1: you in your ninety six buick. 28 00:01:22,120 --> 00:01:25,640 Speaker 2: Ahi, Ron, Yes, I have no no rare brake lights, 29 00:01:27,160 --> 00:01:28,959 Speaker 2: just the one that's out in the windshield, the bottom 30 00:01:29,000 --> 00:01:30,200 Speaker 2: of the windshield. 31 00:01:29,880 --> 00:01:32,200 Speaker 1: Okay, at the bottom of the back wind at the 32 00:01:32,200 --> 00:01:35,640 Speaker 1: bottom of the back window. You mean, yeah, okay. 33 00:01:35,400 --> 00:01:37,880 Speaker 2: And the hazard lights don't work all right. 34 00:01:38,080 --> 00:01:43,560 Speaker 1: But but but that third break light works. That that 35 00:01:43,640 --> 00:01:46,720 Speaker 1: middle that third break what was traditionally call a third 36 00:01:46,800 --> 00:01:48,639 Speaker 1: or high mounted stop lamp, that works. 37 00:01:49,800 --> 00:01:50,640 Speaker 2: Yes, okay. 38 00:01:51,040 --> 00:01:55,320 Speaker 1: So if that works, then the brake light switch is 39 00:01:55,320 --> 00:01:58,320 Speaker 1: working because it's triggered directly off the brake light switch. 40 00:01:58,520 --> 00:02:00,440 Speaker 1: What happens is that the break lights switch at the 41 00:02:00,480 --> 00:02:03,120 Speaker 1: base of the pedal. There's an orange in a white wire. 42 00:02:03,200 --> 00:02:05,360 Speaker 1: The orange is hot coming from the fuse, and then 43 00:02:05,400 --> 00:02:07,400 Speaker 1: the wipe comes out and it branches off. It goes 44 00:02:07,440 --> 00:02:10,639 Speaker 1: off into a stop lamp. The stop lamp circuit down 45 00:02:10,639 --> 00:02:14,239 Speaker 1: to the turn signal, and then it goes to the 46 00:02:14,240 --> 00:02:16,919 Speaker 1: third brake light itself. So if the third brake light 47 00:02:17,040 --> 00:02:20,520 Speaker 1: is working, then we know that the stop lamp switch 48 00:02:20,760 --> 00:02:24,240 Speaker 1: is functional. Okay, what parts have you changed already. Let 49 00:02:24,240 --> 00:02:25,040 Speaker 1: me ask that question. 50 00:02:26,680 --> 00:02:31,600 Speaker 2: Just the bults, all the bulbs, Okay, So I have 51 00:02:31,760 --> 00:02:35,600 Speaker 2: my mechanic look at it, and he didn't really want 52 00:02:35,600 --> 00:02:37,120 Speaker 2: to work on it. He said, he thinks it's a 53 00:02:37,160 --> 00:02:38,160 Speaker 2: turn signal switch. 54 00:02:38,320 --> 00:02:40,799 Speaker 1: Probably is, which. 55 00:02:40,600 --> 00:02:43,120 Speaker 2: I wanted to ask you about that. That's not the 56 00:02:43,200 --> 00:02:44,680 Speaker 2: multifunction switch, is it. 57 00:02:44,919 --> 00:02:47,919 Speaker 1: Well, that's the one that the turn signals are on. Well, 58 00:02:48,080 --> 00:02:52,919 Speaker 1: the multifunction switch. Let's not get confused. The multifunction switch 59 00:02:52,960 --> 00:02:56,400 Speaker 1: you're talking about in reference to what turns the wipers on? Correct? 60 00:02:57,320 --> 00:02:58,720 Speaker 2: Yeah, all of those work. 61 00:02:58,680 --> 00:03:04,920 Speaker 1: Right, right, because because that multifunction switch, or that lever, 62 00:03:05,120 --> 00:03:08,720 Speaker 1: let me call it a lever. That lever, if you notice, 63 00:03:08,720 --> 00:03:10,640 Speaker 1: has a wire coming off the bottom of it, and 64 00:03:10,680 --> 00:03:13,040 Speaker 1: it kind of tucks neatly into the steering column and 65 00:03:13,080 --> 00:03:16,240 Speaker 1: then disappears down into the column. Right, that's got a 66 00:03:16,280 --> 00:03:19,720 Speaker 1: separate all the all the turn signal switch does is 67 00:03:19,800 --> 00:03:23,600 Speaker 1: hold that lever. All right. You could, you could, you 68 00:03:23,639 --> 00:03:25,840 Speaker 1: could take that lever out, You could pop that lever out, 69 00:03:25,919 --> 00:03:28,160 Speaker 1: lay it on the dashboard and when you wanted to 70 00:03:28,240 --> 00:03:29,920 Speaker 1: reach up and but you have no way to activate 71 00:03:29,919 --> 00:03:32,520 Speaker 1: the turn signals if you follow what I'm saying. So 72 00:03:32,800 --> 00:03:34,280 Speaker 1: you know when they call it. When they call it 73 00:03:34,320 --> 00:03:38,000 Speaker 1: a multifunction switch, that is a separate switch in function 74 00:03:38,240 --> 00:03:41,320 Speaker 1: and form and fit from the turn signal switch. It 75 00:03:41,440 --> 00:03:43,840 Speaker 1: just happened to be connected to the two of them, 76 00:03:44,280 --> 00:03:47,960 Speaker 1: all right, So yeah, don't don't get the two confused 77 00:03:48,680 --> 00:03:51,520 Speaker 1: going into the turn signal switch. What GM did was 78 00:03:51,560 --> 00:03:53,600 Speaker 1: they came out of the stop lamb fuse. They ran 79 00:03:53,680 --> 00:03:56,040 Speaker 1: it right down to the brake light switch. Coming out 80 00:03:56,040 --> 00:03:57,720 Speaker 1: of the brake light switch, they came out with a 81 00:03:57,720 --> 00:04:00,360 Speaker 1: white wire. Is this a four door car or a 82 00:04:00,400 --> 00:04:04,920 Speaker 1: two door car? Two door coop? Okay, that makes it easier. 83 00:04:04,920 --> 00:04:07,040 Speaker 1: The four door cars. There was a few of those built. 84 00:04:07,040 --> 00:04:08,600 Speaker 1: It's hard to find the part. It's hard to find 85 00:04:08,600 --> 00:04:11,400 Speaker 1: the wiring diagram, but suffice it to say that it 86 00:04:11,400 --> 00:04:13,600 Speaker 1: comes out as a white wire. I would go down 87 00:04:13,640 --> 00:04:17,880 Speaker 1: to the directional switch and where that white wire comes in. 88 00:04:18,240 --> 00:04:20,679 Speaker 1: Do I have hot there? Do I have power there? 89 00:04:21,520 --> 00:04:26,599 Speaker 1: All right? If I have power there, and go back 90 00:04:26,880 --> 00:04:28,560 Speaker 1: to the other side of the switch, I believe it's 91 00:04:28,560 --> 00:04:31,640 Speaker 1: a green wire, green or blue? Do I have anything there? 92 00:04:31,680 --> 00:04:34,440 Speaker 1: If I don't, I've got a bad turn signal switch. 93 00:04:36,040 --> 00:04:38,360 Speaker 1: It's just that it's just that simple. It's not really 94 00:04:38,480 --> 00:04:41,719 Speaker 1: much more complicated than that. The fact that the stop lamp, 95 00:04:41,960 --> 00:04:46,560 Speaker 1: the high mounted stop lamp is working, yeah, tells me 96 00:04:46,640 --> 00:04:48,800 Speaker 1: at all. Now, you know, if we want, if we 97 00:04:48,839 --> 00:04:52,480 Speaker 1: want to test this, all right, and you know, let's 98 00:04:52,560 --> 00:04:55,160 Speaker 1: let's just say we didn't have the ability to look 99 00:04:55,200 --> 00:04:56,599 Speaker 1: at the third brake light and say, hey, is it 100 00:04:56,640 --> 00:04:58,880 Speaker 1: working or not? The way I could verify if the 101 00:04:58,880 --> 00:05:02,400 Speaker 1: switch is working is two different ways. Do we have 102 00:05:02,440 --> 00:05:05,400 Speaker 1: a scan tool? If we have a scan tool and 103 00:05:06,120 --> 00:05:08,120 Speaker 1: go into data, do I have because back in the 104 00:05:08,200 --> 00:05:11,159 Speaker 1: nineties they love to do this, Do I have a PID? 105 00:05:11,200 --> 00:05:13,560 Speaker 1: Do I have a data piece on the scan tool 106 00:05:13,640 --> 00:05:16,760 Speaker 1: for stomp lamp switch on off? And it'll change when 107 00:05:16,760 --> 00:05:18,719 Speaker 1: you step the step on the brake pedal Because the 108 00:05:18,720 --> 00:05:22,880 Speaker 1: computer needed to see brake light operation to kick the 109 00:05:22,920 --> 00:05:26,000 Speaker 1: trends out of overdrive, so they had it was it 110 00:05:26,040 --> 00:05:27,760 Speaker 1: was sort of a requirement that it would be there 111 00:05:27,760 --> 00:05:29,640 Speaker 1: on a scan tool, so you could diagnose it that way. 112 00:05:29,880 --> 00:05:31,320 Speaker 1: The other way you could do this is does the 113 00:05:31,320 --> 00:05:32,480 Speaker 1: car have cruise control? 114 00:05:34,720 --> 00:05:34,960 Speaker 2: Yeah? 115 00:05:35,120 --> 00:05:35,760 Speaker 1: Does it work? 116 00:05:37,200 --> 00:05:38,520 Speaker 2: I never I never used it. 117 00:05:38,760 --> 00:05:41,040 Speaker 1: Try it it, take it out for a ride. If 118 00:05:41,040 --> 00:05:43,200 Speaker 1: the cruise control works and you step on the brake 119 00:05:43,240 --> 00:05:46,000 Speaker 1: pedal and it stops working. The brake light switch is working. 120 00:05:46,160 --> 00:05:48,599 Speaker 1: That's another way you could test it. Because they looked 121 00:05:48,600 --> 00:05:50,159 Speaker 1: at they looked at brake lay They figured if you 122 00:05:50,160 --> 00:05:51,960 Speaker 1: were you know, if you're hitting the brakes, you wanted 123 00:05:52,000 --> 00:05:55,560 Speaker 1: to turn off the cruise right then you didn't want 124 00:05:55,560 --> 00:05:58,040 Speaker 1: to keep going. But it sounds like to me, for 125 00:05:58,160 --> 00:06:01,320 Speaker 1: my money, you've got a bed turn signal switch. Now 126 00:06:01,320 --> 00:06:03,960 Speaker 1: you've got to find one, you know. 127 00:06:04,360 --> 00:06:07,640 Speaker 2: Now, that's the that's the multi function one you're talking about. 128 00:06:07,760 --> 00:06:13,520 Speaker 1: No, that's the one inside. That's the one inside the column. Right, 129 00:06:13,600 --> 00:06:16,280 Speaker 1: that's the piece inside with the long wiring harness. It's 130 00:06:16,279 --> 00:06:18,039 Speaker 1: going to run down to the base of the column, 131 00:06:19,680 --> 00:06:23,799 Speaker 1: all right, Different different companies will make that. The first 132 00:06:23,839 --> 00:06:26,719 Speaker 1: place I would go look for that switch is Standard 133 00:06:26,760 --> 00:06:31,920 Speaker 1: Motor Products s MP. S MP made those switches back 134 00:06:31,920 --> 00:06:34,800 Speaker 1: in the day, and I believe they still do all right, 135 00:06:34,839 --> 00:06:36,760 Speaker 1: and they made a great quality piece. So I would 136 00:06:36,800 --> 00:06:38,560 Speaker 1: be looking for one of those. And if they're not 137 00:06:38,560 --> 00:06:42,080 Speaker 1: making it anymore, there's probably some somewhere that some motor 138 00:06:42,160 --> 00:06:44,400 Speaker 1: parts house has on the shelf. Not quite sure what 139 00:06:44,440 --> 00:06:46,119 Speaker 1: to do with it, because how many ninety six Buick 140 00:06:46,200 --> 00:06:50,360 Speaker 1: Rivieras are left right. Yeah, so great, great cars, fun 141 00:06:50,400 --> 00:06:54,080 Speaker 1: cars man, So all right, love it. But you could 142 00:06:54,640 --> 00:06:58,719 Speaker 1: you could, you could probably go online Google search Standard 143 00:06:58,720 --> 00:07:02,279 Speaker 1: Motor Products and I bet they've got an online catalog. 144 00:07:02,279 --> 00:07:03,760 Speaker 1: I bet you could even look it up online and 145 00:07:03,800 --> 00:07:05,280 Speaker 1: see what the partnermber is. So at least you know 146 00:07:05,320 --> 00:07:06,039 Speaker 1: what you're looking for. 147 00:07:07,640 --> 00:07:10,920 Speaker 2: Okay, great, all right, yep, yeah, thank you. 148 00:07:10,920 --> 00:07:12,360 Speaker 1: You're very welcome, sir. You have a great rest of 149 00:07:12,400 --> 00:07:16,080 Speaker 1: the day. Let's go over to Let's go over to 150 00:07:16,160 --> 00:07:19,160 Speaker 1: Walter in Pennsylvania. Walter, you're up ron an Indian at 151 00:07:19,160 --> 00:07:21,960 Speaker 1: your service? How can I help? Yes, sir, Yeah, So. 152 00:07:21,920 --> 00:07:25,720 Speaker 6: I have a twenty twelve RAM with a HEMY five 153 00:07:25,760 --> 00:07:30,200 Speaker 6: point seven. In October. This passed October, the EVAP check 154 00:07:30,240 --> 00:07:34,880 Speaker 6: engine light system came on code zero four four one. 155 00:07:35,000 --> 00:07:40,200 Speaker 6: I replaced the gas cab, and I replaced the vapor 156 00:07:40,280 --> 00:07:43,160 Speaker 6: canistare which is under the hood, and I replaced the 157 00:07:43,200 --> 00:07:45,520 Speaker 6: EVAPP emission system. 158 00:07:45,240 --> 00:07:50,960 Speaker 1: Leak of affortive system integrity monitor right right, the little 159 00:07:50,960 --> 00:07:53,280 Speaker 1: white the little white and black piece that's bolted to 160 00:07:53,280 --> 00:07:54,640 Speaker 1: the side of the charcoal canister. 161 00:07:55,440 --> 00:08:00,000 Speaker 6: Right, and so the light turned off and last week 162 00:08:00,000 --> 00:08:03,440 Speaker 6: think the light turned on again. Okay, should I replace 163 00:08:03,520 --> 00:08:04,760 Speaker 6: all these things again. 164 00:08:04,600 --> 00:08:09,280 Speaker 1: No, you should get it diagnosed, all right. So so 165 00:08:09,280 --> 00:08:11,880 Speaker 1: so let's let's talk about this for a second. You 166 00:08:12,120 --> 00:08:17,280 Speaker 1: changed the purge valve right, the piece up front, correct? Okay? Yeah, 167 00:08:17,280 --> 00:08:18,280 Speaker 1: you called it a canister. 168 00:08:19,680 --> 00:08:23,000 Speaker 6: Well, no, there's two things. And also the evappumission leak 169 00:08:23,120 --> 00:08:28,720 Speaker 6: detection uh thing it has it's underneath the car. 170 00:08:28,680 --> 00:08:32,440 Speaker 1: Right, Where's where's them mounted? Them is mounted on the canister. 171 00:08:34,760 --> 00:08:38,400 Speaker 6: The vapor cannister is under the hood. It's like kind 172 00:08:38,440 --> 00:08:39,560 Speaker 6: of the driver's side fender. 173 00:08:39,920 --> 00:08:42,640 Speaker 1: Okay, and that's and that's where them is mounted. Correct. 174 00:08:43,400 --> 00:08:43,760 Speaker 2: Correct? 175 00:08:43,800 --> 00:08:45,480 Speaker 1: Okay, I'm just trying to make sure we're talking about 176 00:08:45,480 --> 00:08:47,000 Speaker 1: the same pieces that has. 177 00:08:47,080 --> 00:08:49,679 Speaker 6: Yeah, that has two lines to it and then an 178 00:08:49,720 --> 00:08:52,720 Speaker 6: electrical line, right, and then the one underneath it only 179 00:08:52,760 --> 00:08:57,520 Speaker 6: has like an electrical sensor and a thick washer. 180 00:08:57,920 --> 00:09:00,400 Speaker 1: Okay, all right, so here let me I mean, do 181 00:09:00,400 --> 00:09:03,000 Speaker 1: you understand how evapp works, walt or what it does? 182 00:09:03,080 --> 00:09:07,680 Speaker 6: Yes, I know I've read the very finicky with these 183 00:09:07,720 --> 00:09:08,440 Speaker 6: things right. 184 00:09:08,520 --> 00:09:13,280 Speaker 1: Well, the the the ESUM system that ESOM monitor. What 185 00:09:13,440 --> 00:09:16,920 Speaker 1: happens is when you shut the vehicle off, it counts 186 00:09:16,960 --> 00:09:21,440 Speaker 1: on a very very very very very very small change 187 00:09:21,880 --> 00:09:26,240 Speaker 1: in fuel pressure, vapor pressure, pushing the pushing the switch 188 00:09:26,400 --> 00:09:29,560 Speaker 1: over to close, to show that the system has integrity. 189 00:09:29,840 --> 00:09:31,560 Speaker 1: You've ever been to a small town carnival and you 190 00:09:31,600 --> 00:09:34,920 Speaker 1: got the little skinny guy with the the that rings 191 00:09:34,920 --> 00:09:36,640 Speaker 1: the bell. You hit the hammer and then goes dang 192 00:09:36,679 --> 00:09:39,040 Speaker 1: and the bell goes right. Yes, that thing. That's kind 193 00:09:39,080 --> 00:09:42,160 Speaker 1: of what an m is, all right, it's it's gotta have. 194 00:09:42,240 --> 00:09:45,120 Speaker 1: It's got to have system integrity. A leak in the 195 00:09:45,200 --> 00:09:48,839 Speaker 1: system thinner than a piece of hair on your head 196 00:09:49,320 --> 00:09:50,880 Speaker 1: will cause that system to fail. 197 00:09:51,840 --> 00:09:52,200 Speaker 6: All right. 198 00:09:53,920 --> 00:09:58,800 Speaker 1: So so being what this is, if we can't test it, 199 00:09:59,520 --> 00:10:01,439 Speaker 1: and the way I would test it is I would 200 00:10:01,440 --> 00:10:06,640 Speaker 1: put this vehicle into it's evaporative state where I would 201 00:10:06,679 --> 00:10:09,440 Speaker 1: run it, run the monitor, and then it will it 202 00:10:09,480 --> 00:10:12,120 Speaker 1: will show me that the system is in a vapor state, 203 00:10:12,240 --> 00:10:15,000 Speaker 1: closing the bell, and then I can count how long 204 00:10:15,080 --> 00:10:18,400 Speaker 1: it takes before the signal degrades. All right. The other 205 00:10:18,400 --> 00:10:20,720 Speaker 1: way I'm going to do it is using a smoke machine, 206 00:10:21,280 --> 00:10:22,960 Speaker 1: and I'm going to be I'm gonna be I'm going 207 00:10:23,040 --> 00:10:26,040 Speaker 1: to be gingerly with my smoke, because smoke can create 208 00:10:26,160 --> 00:10:29,040 Speaker 1: enough pressure to overcome some of these and actually never 209 00:10:29,080 --> 00:10:31,920 Speaker 1: find the leak. The other thing I'm going to do 210 00:10:32,280 --> 00:10:38,079 Speaker 1: is you have black plastic, hard plastic tubing rubber elbows 211 00:10:38,280 --> 00:10:42,120 Speaker 1: under the hood right for the EVAP system. Why don't 212 00:10:42,160 --> 00:10:46,400 Speaker 1: you go around very gently and very gently try do 213 00:10:46,440 --> 00:10:52,120 Speaker 1: they twist? If they twist, that's movement. If they've got movement, 214 00:10:52,320 --> 00:10:56,839 Speaker 1: that's a leak. Brother, all right. And there was actually 215 00:10:56,880 --> 00:10:59,720 Speaker 1: a few bulletins from Chrysler talking about replacing the tube 216 00:11:00,000 --> 00:11:05,200 Speaker 1: eblis on these vehicles. Now I'm assuming, well I'm using 217 00:11:05,200 --> 00:11:08,640 Speaker 1: that word a lot this weekend, that them you bought 218 00:11:09,480 --> 00:11:13,240 Speaker 1: is good, all right. I've seen bad new ones out 219 00:11:13,240 --> 00:11:15,120 Speaker 1: of the gate from Chrysler. I've seen bad new ones 220 00:11:15,160 --> 00:11:18,600 Speaker 1: out of the gate in the aftermarket. It happens, all right. 221 00:11:18,679 --> 00:11:20,679 Speaker 1: The other thing you could do is do you own 222 00:11:20,679 --> 00:11:21,640 Speaker 1: a vacuum gauge. 223 00:11:24,920 --> 00:11:27,319 Speaker 6: I I don't think I have one, but I'm sure 224 00:11:27,320 --> 00:11:28,000 Speaker 6: I could find one. 225 00:11:28,080 --> 00:11:29,720 Speaker 1: Okay, I tell you what. Stay on the line a minute, 226 00:11:29,760 --> 00:11:31,240 Speaker 1: let me pull over, take a pause. When I come back, 227 00:11:31,240 --> 00:11:32,360 Speaker 1: I want to explain to you how I want you 228 00:11:32,400 --> 00:11:34,160 Speaker 1: to do this test at the Purge valve. I'm running 229 00:11:34,200 --> 00:11:52,679 Speaker 1: any in the car. Doctor will return right after this time. 230 00:11:53,200 --> 00:11:55,080 Speaker 6: Ride it on the wall, so you don't forget to 231 00:11:55,120 --> 00:11:56,160 Speaker 6: call for car advice. 232 00:11:56,280 --> 00:11:59,360 Speaker 1: Done right? Eight five five five six zero nine nine 233 00:11:59,440 --> 00:12:04,439 Speaker 1: zero zero. Now back to Ron Walter. You're still there. Yeah, 234 00:12:04,520 --> 00:12:06,360 Speaker 1: I want to go back over something you said. I 235 00:12:06,400 --> 00:12:11,520 Speaker 1: was thinking about it. Them theom the three quarters of 236 00:12:11,559 --> 00:12:16,000 Speaker 1: it is a white plastic going to a black base, correct, correct, Okay, 237 00:12:16,080 --> 00:12:20,200 Speaker 1: it's got a big fat hose, right, used the used 238 00:12:20,200 --> 00:12:22,880 Speaker 1: a rubber row ring with a push tab. Right that 239 00:12:23,600 --> 00:12:27,360 Speaker 1: it's sort of ninety degree screwed into the counter, into 240 00:12:27,400 --> 00:12:28,800 Speaker 1: the into the charcoal canister. 241 00:12:29,280 --> 00:12:31,360 Speaker 6: Yeah, it's probably like a quarter yeah. 242 00:12:31,200 --> 00:12:33,360 Speaker 1: Quarter turn Okay, all right, just to make sure we're 243 00:12:33,400 --> 00:12:36,400 Speaker 1: on the right page. So that's the back door of 244 00:12:36,440 --> 00:12:38,800 Speaker 1: an evaporative system, and I'll explain that in a second. 245 00:12:39,240 --> 00:12:41,560 Speaker 1: The front door is the purge valve. The purge valve 246 00:12:41,600 --> 00:12:44,800 Speaker 1: is located where over by the passenger side front corner 247 00:12:44,840 --> 00:12:45,920 Speaker 1: of the radiator support. 248 00:12:46,760 --> 00:12:49,000 Speaker 6: Uh, driver's side fender. 249 00:12:48,880 --> 00:12:52,200 Speaker 1: Driver's side fender. So so the so the canister and 250 00:12:52,240 --> 00:12:54,160 Speaker 1: the purge are both, yes, they are. It is on 251 00:12:54,200 --> 00:12:56,720 Speaker 1: the it is on the driver's side fender, okay. And 252 00:12:56,800 --> 00:12:59,840 Speaker 1: the purge valve has two vacuum lines going to it, right, 253 00:13:01,280 --> 00:13:06,600 Speaker 1: and it has one two wire connector one one right, 254 00:13:06,679 --> 00:13:12,080 Speaker 1: it has one two wire connector yeah right, okay, So 255 00:13:12,400 --> 00:13:15,439 Speaker 1: the purge valve is the front door of an EVAP system. 256 00:13:15,600 --> 00:13:18,920 Speaker 1: And the way this works is if you look at 257 00:13:18,920 --> 00:13:20,720 Speaker 1: your house, you have a front door and a back door. 258 00:13:20,920 --> 00:13:22,920 Speaker 1: If you want to get air to go through the house, 259 00:13:23,040 --> 00:13:24,439 Speaker 1: you have to open up the back door in the 260 00:13:24,440 --> 00:13:28,680 Speaker 1: front door, right, So air flows through. So when they 261 00:13:28,720 --> 00:13:31,760 Speaker 1: want to clean out the canister that's been storing fuel 262 00:13:31,760 --> 00:13:35,920 Speaker 1: tank fumes, they open up the um and they open 263 00:13:36,040 --> 00:13:39,400 Speaker 1: up the purge and they allow air to flow through, 264 00:13:39,920 --> 00:13:43,160 Speaker 1: come through the canister out and up feeds the and 265 00:13:43,200 --> 00:13:45,560 Speaker 1: comes up the line for purge, comes up through the 266 00:13:45,559 --> 00:13:49,800 Speaker 1: purge valve, goes into the engine to be burned. Makes sense, okay, 267 00:13:50,160 --> 00:13:55,400 Speaker 1: if you electrically disconnect the purge valve, all right, A 268 00:13:55,440 --> 00:13:59,400 Speaker 1: purge valve is normally closed. It is computer commanded on 269 00:14:00,040 --> 00:14:04,720 Speaker 1: you with me, yes, all right, disconnect it if you 270 00:14:05,040 --> 00:14:08,880 Speaker 1: If you disconnect it, that valve is closed. The front 271 00:14:08,880 --> 00:14:11,480 Speaker 1: door of the house is closed. It's it's it's shut, 272 00:14:12,240 --> 00:14:14,920 Speaker 1: all right. If you close the front door to your house, 273 00:14:14,920 --> 00:14:19,200 Speaker 1: do you have any air leaks? You shouldn't in theory, right, 274 00:14:20,040 --> 00:14:23,840 Speaker 1: So same thing with this so one of those two vacuum, 275 00:14:24,000 --> 00:14:25,640 Speaker 1: one of those two rubber hoses is going to be 276 00:14:25,680 --> 00:14:30,280 Speaker 1: engine manifold vacuum. All right. If you were to start 277 00:14:30,280 --> 00:14:34,560 Speaker 1: the truck up with the purge valve disconnected, electrically disconnected, 278 00:14:35,200 --> 00:14:37,760 Speaker 1: and you pulled those rubber hoses off, one of them 279 00:14:37,800 --> 00:14:40,640 Speaker 1: is going to have vacuum and that's that's going to 280 00:14:40,720 --> 00:14:44,880 Speaker 1: the engine and the other one is feed going from 281 00:14:45,000 --> 00:14:50,320 Speaker 1: coming from the canister. Right. I want you to take 282 00:14:50,360 --> 00:14:53,400 Speaker 1: that two line rubber hose and twist it and I 283 00:14:53,440 --> 00:14:57,000 Speaker 1: want you to put just the vacuum side onto the 284 00:14:57,000 --> 00:15:02,400 Speaker 1: purge valve. Okay, all right, So now start the truck. 285 00:15:03,640 --> 00:15:06,880 Speaker 1: The valve is the valve is mechanically closed, right, it 286 00:15:06,960 --> 00:15:11,880 Speaker 1: can't be electrically activated, right, all right. If you put 287 00:15:11,920 --> 00:15:15,000 Speaker 1: a vacuum gauge on the other side of the purge valve, 288 00:15:15,000 --> 00:15:18,880 Speaker 1: that's that's you know where the nipples hanging open. Right, 289 00:15:19,000 --> 00:15:20,200 Speaker 1: what will that read? 290 00:15:21,680 --> 00:15:22,120 Speaker 6: Well, that. 291 00:15:23,760 --> 00:15:29,000 Speaker 1: Well should read zero, okay, right, because it's mechanically closed. 292 00:15:30,400 --> 00:15:33,240 Speaker 1: All right. I'm pushing I'm pushing your envelope today, buddy. 293 00:15:33,560 --> 00:15:34,920 Speaker 1: All right. I want I want to get you to 294 00:15:34,960 --> 00:15:39,040 Speaker 1: understand this. If that if that purge valve is mechanically closed, 295 00:15:39,280 --> 00:15:43,160 Speaker 1: and it's got engine vacuum being applied to it. Right, 296 00:15:44,000 --> 00:15:47,080 Speaker 1: we should not see vacuum on the other side. And 297 00:15:47,120 --> 00:15:49,080 Speaker 1: if we don't see vacuum on the other side, you've 298 00:15:49,080 --> 00:15:52,160 Speaker 1: got a good purge valve. This is a five minute test. 299 00:15:52,680 --> 00:15:54,560 Speaker 1: What I'm doing is I'm trying to teach you to 300 00:15:54,640 --> 00:15:57,560 Speaker 1: test this without anything expensive. You will need a scan 301 00:15:57,640 --> 00:15:59,360 Speaker 1: tool to clear the codes that we're about to set. 302 00:15:59,840 --> 00:16:03,280 Speaker 1: So know that, know that going in, all right, If 303 00:16:03,280 --> 00:16:07,000 Speaker 1: that purge valve passes the test, the purge is good. 304 00:16:07,040 --> 00:16:10,440 Speaker 1: Take it off the list, all right, Go and check. 305 00:16:10,640 --> 00:16:15,040 Speaker 1: Go and check your rubber plastic elbow connections and fittings, 306 00:16:15,040 --> 00:16:17,000 Speaker 1: and it doesn't take much. You'll see you'll start to 307 00:16:17,040 --> 00:16:19,160 Speaker 1: play with them. And if I remember right, the one 308 00:16:19,160 --> 00:16:21,000 Speaker 1: at the base of the throttle body was the most 309 00:16:21,000 --> 00:16:25,960 Speaker 1: susceptible to failure, all right, because I believe that vacuum 310 00:16:25,960 --> 00:16:27,880 Speaker 1: line coming from the purge valve is going to lead 311 00:16:27,960 --> 00:16:30,440 Speaker 1: right to the base of the throttle body or the 312 00:16:30,480 --> 00:16:33,600 Speaker 1: intake or the or the intake, and you're going to 313 00:16:33,680 --> 00:16:36,680 Speaker 1: find that one of those plastic tubes turns in the elbow, 314 00:16:37,640 --> 00:16:41,560 Speaker 1: all right, Now, don't don't hercules this all right, you 315 00:16:41,600 --> 00:16:44,960 Speaker 1: know I'll prove it's bad. You know, No, this is 316 00:16:45,400 --> 00:16:49,440 Speaker 1: this is this is about being gentle, all right, because 317 00:16:49,520 --> 00:16:54,000 Speaker 1: we're we're looking for something that occurs. You know, an 318 00:16:54,040 --> 00:16:57,720 Speaker 1: evapp leak on this vehicle can occur because of a 319 00:16:57,840 --> 00:17:01,720 Speaker 1: temperature change, expansion and control. That's what makes these so 320 00:17:01,840 --> 00:17:06,679 Speaker 1: hard to find, right, all right? If if I find 321 00:17:06,920 --> 00:17:12,000 Speaker 1: nothing else, all right, I've eliminated purge, I've eliminated the lines. 322 00:17:12,320 --> 00:17:14,160 Speaker 1: You don't have a smoke machine. I'm trying to get 323 00:17:14,200 --> 00:17:16,959 Speaker 1: you through this. You know, my choice is do I 324 00:17:17,040 --> 00:17:20,560 Speaker 1: have a bad new ESM. It's possible. It's it's easy 325 00:17:20,560 --> 00:17:23,160 Speaker 1: to try a second one. They're cheap enough. I would 326 00:17:23,200 --> 00:17:26,240 Speaker 1: tell you. I would be certain that you've got a 327 00:17:26,280 --> 00:17:29,000 Speaker 1: good seal. Where that orange O ring is on the canister, 328 00:17:30,359 --> 00:17:32,200 Speaker 1: that it's not pinched, right. 329 00:17:32,880 --> 00:17:36,320 Speaker 6: Yeah, I think so. It clips on, there's a lock. 330 00:17:36,200 --> 00:17:38,320 Speaker 1: On it, right. Sometimes the O ring falls out of 331 00:17:38,359 --> 00:17:40,880 Speaker 1: placement when you go to put it on. The Other 332 00:17:40,920 --> 00:17:43,840 Speaker 1: thing you could try is, you know, a dab of 333 00:17:43,840 --> 00:17:46,320 Speaker 1: what I call yellow grease, the industry calls it white 334 00:17:46,400 --> 00:17:50,320 Speaker 1: lithium grease. Just a small shmerrhor grease on that O 335 00:17:50,520 --> 00:17:52,879 Speaker 1: ring and then put the esum on just enough to 336 00:17:52,920 --> 00:17:55,159 Speaker 1: give a little suppleness to the nipple so that it 337 00:17:55,200 --> 00:17:58,760 Speaker 1: doesn't it doesn't bunch up. And see if that gets 338 00:17:58,760 --> 00:18:00,480 Speaker 1: at the seal a little bit better. A couple of 339 00:18:00,480 --> 00:18:02,080 Speaker 1: things for you to try, Walter, you need more. You 340 00:18:02,080 --> 00:18:04,000 Speaker 1: know where I am eight five five five six zero 341 00:18:04,240 --> 00:18:06,200 Speaker 1: nine nine zero zero on an eating the car. Doctor. 342 00:18:06,200 --> 00:18:39,760 Speaker 1: I'll be back right after this. And where are we 343 00:18:39,800 --> 00:18:41,800 Speaker 1: going now? Let's go to Don and Iowa waiting a 344 00:18:41,920 --> 00:18:45,119 Speaker 1: very patiently two thousand Chevy Blazer. God, Don, I remember 345 00:18:45,160 --> 00:18:48,800 Speaker 1: these vehicles. You might have the last one left in America. 346 00:18:48,960 --> 00:18:50,280 Speaker 1: How many miles you go? This thing? 347 00:18:51,440 --> 00:18:54,160 Speaker 3: It's got two hundred and fifteen thousand on it. Wow? 348 00:18:54,680 --> 00:18:57,240 Speaker 1: So and the frame hasn't rusted out yet. I'm not 349 00:18:57,280 --> 00:18:59,840 Speaker 1: Pierre around. I'm just really yeah, I just I remember 350 00:18:59,840 --> 00:19:03,320 Speaker 1: these were they just rotted away like you know it was, 351 00:19:03,960 --> 00:19:05,840 Speaker 1: and they were great vehicles. I love them. They were 352 00:19:05,880 --> 00:19:08,159 Speaker 1: just so much fun. They're the right size. There's a 353 00:19:08,200 --> 00:19:08,560 Speaker 1: lot in. 354 00:19:08,560 --> 00:19:11,320 Speaker 3: The age, yes, but what I'm doing it's exactly the 355 00:19:11,400 --> 00:19:14,960 Speaker 3: right size. And it's got the ear shift on the 356 00:19:15,000 --> 00:19:17,160 Speaker 3: columns like and drive it from the other side. 357 00:19:17,280 --> 00:19:20,000 Speaker 1: Yep, yeah, yeah, I get you. What's going on with. 358 00:19:19,960 --> 00:19:23,880 Speaker 3: This thing, Well, it's laying down on me. By that, 359 00:19:23,960 --> 00:19:26,320 Speaker 3: I mean about about an hour and a half out 360 00:19:26,359 --> 00:19:29,800 Speaker 3: on the route, it'll start. The first thing is that 361 00:19:29,920 --> 00:19:32,919 Speaker 3: if you notice it's not shifting into high gear. You know, 362 00:19:33,320 --> 00:19:36,320 Speaker 3: at about fifty mile an hour, you look over here 363 00:19:36,320 --> 00:19:39,400 Speaker 3: the engines are having about four grand and find if 364 00:19:39,400 --> 00:19:42,280 Speaker 3: you let off, it'll maybe shift in, and then it'll sputter, 365 00:19:42,359 --> 00:19:46,680 Speaker 3: and it keeps getting worse to eventually it'll just it'll 366 00:19:46,720 --> 00:19:49,840 Speaker 3: just kill off, kill right off on you kill off. 367 00:19:49,840 --> 00:19:52,639 Speaker 1: When you say kill off down, do you mean that. 368 00:19:53,160 --> 00:19:55,359 Speaker 3: The truck it's engine will shut down. 369 00:19:55,400 --> 00:19:57,880 Speaker 1: It'll shut off. Yes, okay. 370 00:19:58,320 --> 00:20:01,720 Speaker 3: And then if you it said about five minutes, well 371 00:20:01,680 --> 00:20:03,639 Speaker 3: a lot of times that happened. It'll get do that. 372 00:20:03,680 --> 00:20:06,120 Speaker 3: About time I get back into the into the town. 373 00:20:06,440 --> 00:20:07,840 Speaker 3: I got to go to a rest home, so I 374 00:20:07,840 --> 00:20:10,840 Speaker 3: go inside there do their mail. Then I come out 375 00:20:10,880 --> 00:20:14,440 Speaker 3: and that's about the midway point. Then I reshuffle my load, 376 00:20:14,560 --> 00:20:17,080 Speaker 3: you know, and then I take off. And then while 377 00:20:17,119 --> 00:20:19,280 Speaker 3: I'm in town, you know, you're not really pushing it 378 00:20:19,359 --> 00:20:22,880 Speaker 3: very hard. It'll run, you know, and then you get 379 00:20:22,920 --> 00:20:25,600 Speaker 3: back out in the cot. But it's temperature related, because 380 00:20:27,359 --> 00:20:29,560 Speaker 3: a really warm day it gets awful on. 381 00:20:29,400 --> 00:20:33,439 Speaker 1: You, okay, and any any diagnostics or any testing been 382 00:20:33,480 --> 00:20:34,480 Speaker 1: done to this point. 383 00:20:34,840 --> 00:20:36,840 Speaker 3: Well, yes, as a matter of fact, it did this 384 00:20:36,920 --> 00:20:39,240 Speaker 3: to me a week ago. A week ago Friday, it 385 00:20:39,320 --> 00:20:42,000 Speaker 3: was really warm here in Iowa, and the guy that 386 00:20:42,040 --> 00:20:45,120 Speaker 3: I've had work on it, I called him up and said, 387 00:20:45,160 --> 00:20:47,160 Speaker 3: I'm bringing it up to you. It's doing it terrible. 388 00:20:47,200 --> 00:20:50,920 Speaker 3: So he got in with a scan tool and anyhow 389 00:20:51,240 --> 00:20:54,200 Speaker 3: he came up with a couple of o he said, well, 390 00:20:54,240 --> 00:20:57,280 Speaker 3: your oxygen senses don't look right. He said, God, I'd 391 00:20:57,320 --> 00:20:59,800 Speaker 3: never seen oxygen says to made or run this bad. 392 00:21:00,000 --> 00:21:03,720 Speaker 1: Either for the fact of it right, And what did 393 00:21:03,720 --> 00:21:04,760 Speaker 1: he do? Did he do anything? 394 00:21:05,400 --> 00:21:08,359 Speaker 3: Well, he was busy then. But then I got essentially 395 00:21:08,400 --> 00:21:11,920 Speaker 3: I had it up there yesterday and he put two 396 00:21:12,040 --> 00:21:16,120 Speaker 3: oxygen sensors in it. And then I told him while 397 00:21:16,119 --> 00:21:19,919 Speaker 3: he had it out, he said, oh yeah, he knew about, 398 00:21:19,960 --> 00:21:23,280 Speaker 3: you know, checking for a plug converter with the pressure gauge, 399 00:21:23,320 --> 00:21:26,520 Speaker 3: and he said there was no problem with that, and 400 00:21:28,680 --> 00:21:33,320 Speaker 3: anyhow he did that. And then also, oh, the friday 401 00:21:33,359 --> 00:21:35,080 Speaker 3: before he told me he said, you know, e g 402 00:21:35,320 --> 00:21:37,639 Speaker 3: r vels and knowing to caused lots of troubles with 403 00:21:37,680 --> 00:21:41,720 Speaker 3: these things. He said that you could do yourself, which 404 00:21:41,760 --> 00:21:43,199 Speaker 3: I could. It was a ten minute It was a 405 00:21:43,240 --> 00:21:45,960 Speaker 3: ten minute and one hundred dollars later type deal. And 406 00:21:45,960 --> 00:21:48,520 Speaker 3: he didn't do a thing for it. And also he 407 00:21:48,720 --> 00:21:52,160 Speaker 3: changed he cleaned the throttle body and I think he said, 408 00:21:52,200 --> 00:21:54,480 Speaker 3: like the idle air controller. He cleaned that up. 409 00:21:55,080 --> 00:21:59,399 Speaker 1: So what I'm curious about is you're not mentioning fuel pressure. 410 00:22:00,560 --> 00:22:02,560 Speaker 3: H He checked that fuel pressure and it was good. 411 00:22:02,600 --> 00:22:04,240 Speaker 3: He was up like fifty or better, you know. 412 00:22:04,440 --> 00:22:06,720 Speaker 1: Right, Well, hang on a second now, he checked it 413 00:22:06,760 --> 00:22:10,400 Speaker 1: when the vehicle was running. Okay, correct, No, it. 414 00:22:10,359 --> 00:22:12,600 Speaker 3: Was running terrible that day a week ago, all right, 415 00:22:12,920 --> 00:22:16,240 Speaker 3: and what was fuel pressure? Oh, I don't I just 416 00:22:16,359 --> 00:22:19,080 Speaker 3: he stabbed the gauge on. I know it was fifty 417 00:22:19,119 --> 00:22:20,240 Speaker 3: to fifty five right in there. 418 00:22:20,240 --> 00:22:22,800 Speaker 1: All right, Well let me let me let me say 419 00:22:22,800 --> 00:22:25,280 Speaker 1: it like this. If this is a four to three 420 00:22:25,359 --> 00:22:30,200 Speaker 1: W motor, this has this has the snake injector under 421 00:22:30,240 --> 00:22:31,600 Speaker 1: the intake planum. 422 00:22:31,160 --> 00:22:34,080 Speaker 3: Oh the spider yes, yeah, oh. I had him replace 423 00:22:34,160 --> 00:22:35,760 Speaker 3: at him about six weeks ago. 424 00:22:35,920 --> 00:22:40,600 Speaker 1: Okay, well, fifty five the speck is a minimum of 425 00:22:40,680 --> 00:22:44,680 Speaker 1: fifty six at fifty at fifty five, this truck won't run, 426 00:22:45,040 --> 00:22:45,520 Speaker 1: it'll run. 427 00:22:45,880 --> 00:22:48,680 Speaker 3: It'll see that. You know I'm standing off the side, 428 00:22:48,760 --> 00:22:49,840 Speaker 3: but he looked right. 429 00:22:49,960 --> 00:22:52,919 Speaker 1: Listen. My My point is, I want to be exact 430 00:22:52,960 --> 00:22:56,280 Speaker 1: about fuel pressure because if it's if it's at fifty 431 00:22:56,320 --> 00:23:01,199 Speaker 1: five and the minimum accepted value is fifty six, If 432 00:23:01,280 --> 00:23:03,359 Speaker 1: my fuel pressure gaue's been dropped a few times and 433 00:23:03,400 --> 00:23:07,280 Speaker 1: it's off by three percent, guess what that fifty six 434 00:23:07,359 --> 00:23:10,160 Speaker 1: is really fifty three? And now I've got a problem. 435 00:23:10,200 --> 00:23:12,240 Speaker 1: So I want to know what. I want to know 436 00:23:12,240 --> 00:23:14,760 Speaker 1: what real fuel pressure is. Yeah, I get it, I 437 00:23:14,760 --> 00:23:16,160 Speaker 1: get it. But it was running badly, you. 438 00:23:16,119 --> 00:23:20,360 Speaker 3: Said, Okay, well last about August, I had to put 439 00:23:20,359 --> 00:23:21,399 Speaker 3: a new fuel pump in it. 440 00:23:21,520 --> 00:23:26,800 Speaker 1: Okay, what's fuel pressure? Don't assume, don't assume I know. Listen, 441 00:23:27,119 --> 00:23:29,520 Speaker 1: I know you're you're looking for a silver bullet. Second 442 00:23:29,560 --> 00:23:31,600 Speaker 1: time I'm saying that this week, I want to know what. 443 00:23:31,760 --> 00:23:33,520 Speaker 1: I want to know what real fuel pressure is when 444 00:23:33,520 --> 00:23:36,199 Speaker 1: the problem's happening. The other thing, the other thing I 445 00:23:36,240 --> 00:23:38,040 Speaker 1: want to know is I want to go and look 446 00:23:38,080 --> 00:23:40,120 Speaker 1: at I want to go and look at fuel trim. 447 00:23:40,240 --> 00:23:41,840 Speaker 1: I want to know where fuel trim is Is it 448 00:23:41,920 --> 00:23:44,760 Speaker 1: running lean? Is it running rich? All right, if it's 449 00:23:44,840 --> 00:23:48,119 Speaker 1: if it's really running bed, if it's shaking like a 450 00:23:48,240 --> 00:23:52,680 Speaker 1: rough idol, okay, and we think it's e g R, 451 00:23:52,720 --> 00:23:54,840 Speaker 1: where's the EGR position? You can read all this with 452 00:23:54,880 --> 00:23:57,280 Speaker 1: a scan tool. And I'm not saying I'm not saying 453 00:23:57,320 --> 00:24:00,199 Speaker 1: nobody has. I'm just saying, we've got to go through this, 454 00:24:00,680 --> 00:24:04,160 Speaker 1: you know, system by system, step by step, all right, 455 00:24:04,320 --> 00:24:08,040 Speaker 1: older vehicle, higher mileage. We've been throwing parts at it, 456 00:24:08,640 --> 00:24:11,639 Speaker 1: throwing parts at something and not thinking on my soapbox, 457 00:24:11,640 --> 00:24:14,239 Speaker 1: because that's not what you're here for. Throwing parts at 458 00:24:14,280 --> 00:24:17,040 Speaker 1: something may not fix anything. It may inject a new 459 00:24:17,080 --> 00:24:19,720 Speaker 1: problem into the problem, because there's no rule that new 460 00:24:19,760 --> 00:24:21,679 Speaker 1: means good. I can't tell you how many fans I've 461 00:24:21,720 --> 00:24:23,440 Speaker 1: seen that in fifty three years of fixing cars. 462 00:24:23,520 --> 00:24:25,439 Speaker 3: Yes, never ever worry. 463 00:24:25,480 --> 00:24:28,399 Speaker 1: Then you know the story. So I want to know 464 00:24:28,440 --> 00:24:30,680 Speaker 1: what fuel pressure is. I want to know that it's right, 465 00:24:31,320 --> 00:24:33,159 Speaker 1: all right. I want to know that I don't have 466 00:24:33,200 --> 00:24:37,160 Speaker 1: an issue now, you know, let's get past fuel pressure. 467 00:24:37,359 --> 00:24:41,480 Speaker 1: Let's get past looking at fuel trim. The next place 468 00:24:41,520 --> 00:24:45,720 Speaker 1: I'm going to go is, you know, at the time 469 00:24:45,800 --> 00:24:48,200 Speaker 1: of failure, if I take it out on the road 470 00:24:48,240 --> 00:24:51,720 Speaker 1: with a vacuum gauge hooked up. What does the vacuum 471 00:24:51,720 --> 00:24:54,879 Speaker 1: gauge say? And this vehicle, I believe in two thousand 472 00:24:55,880 --> 00:25:01,000 Speaker 1: has a map sensor. What's my map sensor reading mass airflow? Thing? 473 00:25:01,040 --> 00:25:04,719 Speaker 1: And well I think, I think. Don't hold me to this, 474 00:25:04,800 --> 00:25:08,040 Speaker 1: but I thought this had a mass airflow and a map. 475 00:25:08,960 --> 00:25:10,119 Speaker 1: I believe they did both. 476 00:25:11,400 --> 00:25:13,359 Speaker 3: All right, the map is that that little one right 477 00:25:13,400 --> 00:25:14,760 Speaker 3: ahead of the mass airflow one? 478 00:25:14,840 --> 00:25:17,960 Speaker 1: No, that's that's the intake air timp Okay, yeah. 479 00:25:17,800 --> 00:25:18,720 Speaker 3: Yeah, yeah, that's what he said. 480 00:25:18,720 --> 00:25:19,320 Speaker 6: It was right. 481 00:25:19,480 --> 00:25:22,960 Speaker 3: No, I changed that mass airflow about a year ago. Okay, 482 00:25:23,480 --> 00:25:26,480 Speaker 3: Well that that curriage it was doing about the same thing. 483 00:25:26,720 --> 00:25:29,960 Speaker 1: Okay, well that curriage. Well, you know again at the 484 00:25:30,000 --> 00:25:32,840 Speaker 1: point of failure. Has anybody done a full range test 485 00:25:32,840 --> 00:25:34,119 Speaker 1: on the mass airflow sensor? 486 00:25:34,840 --> 00:25:37,439 Speaker 3: Well no, but what I did. I've got a I 487 00:25:37,480 --> 00:25:41,080 Speaker 3: had a ninety six and the mechanic that was my neighbor, 488 00:25:41,080 --> 00:25:43,359 Speaker 3: he said, Well he looked it up. He said, to 489 00:25:43,400 --> 00:25:46,879 Speaker 3: that ninety six there has got the same same part number. 490 00:25:47,320 --> 00:25:49,560 Speaker 3: So I switched it in and that that secured it 491 00:25:49,600 --> 00:25:50,880 Speaker 3: so that I went and bought a new one. 492 00:25:51,000 --> 00:25:53,119 Speaker 1: Right, you know, has anybody tested the new one. 493 00:25:54,880 --> 00:25:57,240 Speaker 3: No, okay, I put I put the other one back 494 00:25:57,280 --> 00:25:59,040 Speaker 3: in again, and it didn't make a bit of difference. 495 00:25:59,160 --> 00:26:02,359 Speaker 1: Right, But you are missing my point. You're you're telling 496 00:26:02,400 --> 00:26:04,439 Speaker 1: me a year ago you changed the mass airflow. Here 497 00:26:04,480 --> 00:26:06,280 Speaker 1: you are a year later, or has this problem been 498 00:26:06,280 --> 00:26:07,200 Speaker 1: going on for a year? 499 00:26:08,040 --> 00:26:12,160 Speaker 3: Well, I I was about a year ago. I changed 500 00:26:12,160 --> 00:26:12,960 Speaker 3: that mass airport. 501 00:26:13,040 --> 00:26:14,879 Speaker 1: When you changed the mass airflow a year ago? Did 502 00:26:14,880 --> 00:26:19,879 Speaker 1: it fix the truck? Well, it's a yes or no answer, 503 00:26:20,200 --> 00:26:22,080 Speaker 1: it's a yes or no answer. 504 00:26:22,520 --> 00:26:25,840 Speaker 3: Yeah, yeah, plus ago again I had that's I put 505 00:26:25,840 --> 00:26:28,800 Speaker 3: the used one out of my other blazer, right, that 506 00:26:29,040 --> 00:26:32,240 Speaker 3: cured it? Okay, Then I so I broke down and 507 00:26:32,240 --> 00:26:34,080 Speaker 3: bought a new one and put it in and put together, 508 00:26:34,280 --> 00:26:37,120 Speaker 3: you know, put the other one back in the other blazer. 509 00:26:37,280 --> 00:26:39,200 Speaker 1: So for a year, this truck's been running fine. 510 00:26:40,440 --> 00:26:43,240 Speaker 3: Oh no, oh, no, it's had other troubles, believe. 511 00:26:43,080 --> 00:26:46,320 Speaker 1: Me, right, but this particular problem has it been running? 512 00:26:46,560 --> 00:26:47,640 Speaker 1: It's been running okay. 513 00:26:48,359 --> 00:26:50,960 Speaker 3: Well, you know the funny thing about this no matter 514 00:26:50,960 --> 00:26:53,240 Speaker 3: what's wrong with it, it always it always does the 515 00:26:53,240 --> 00:26:55,600 Speaker 3: same thing. It takes an hour and a half two 516 00:26:55,640 --> 00:26:58,960 Speaker 3: hours for any problem to you know, show itself. 517 00:26:59,000 --> 00:27:02,119 Speaker 1: So it's had this. It's had this dying off after 518 00:27:02,240 --> 00:27:04,000 Speaker 1: an hour, hour and a half of driving for the 519 00:27:04,080 --> 00:27:06,120 Speaker 1: past two years, is what you're telling me. And all 520 00:27:06,160 --> 00:27:08,480 Speaker 1: the parts that everybody's thrown at it, the parts canon 521 00:27:08,480 --> 00:27:10,920 Speaker 1: that's been sprayed at this vehicle hasn't fixed the thing. 522 00:27:11,520 --> 00:27:14,240 Speaker 3: Yeah, it does fix it for a while, then something 523 00:27:14,240 --> 00:27:15,280 Speaker 3: else happens again. 524 00:27:15,800 --> 00:27:20,719 Speaker 1: And it's the same exact condition pretty much. I'll describe 525 00:27:20,760 --> 00:27:24,680 Speaker 1: it at the point of failure, all right. I want 526 00:27:24,680 --> 00:27:27,520 Speaker 1: to know what fuel pressure is at the point of failure. 527 00:27:27,680 --> 00:27:29,720 Speaker 1: I want to sweep test done to the mass airflow 528 00:27:29,800 --> 00:27:32,520 Speaker 1: sensor at the point of failure. I want to know 529 00:27:32,560 --> 00:27:35,520 Speaker 1: what manifold vacuum is. Anything I test in the bay 530 00:27:35,520 --> 00:27:37,920 Speaker 1: when the vehicle is running good. Anything I test in 531 00:27:37,960 --> 00:27:40,800 Speaker 1: the bay even if the vehicles running slightly rough is 532 00:27:40,800 --> 00:27:44,080 Speaker 1: an invalid test. I have to duplicate the condition. I'm sorry, 533 00:27:44,080 --> 00:27:47,840 Speaker 1: but that's just the way it works, you know, because listen, 534 00:27:48,240 --> 00:27:52,760 Speaker 1: this could be a corroded electrical connector that's affecting computer operation, 535 00:27:53,640 --> 00:27:57,080 Speaker 1: and you know, all you're doing is running around as 536 00:27:57,080 --> 00:28:00,080 Speaker 1: the thing cools off, put apart in something changes. Now 537 00:28:00,080 --> 00:28:03,040 Speaker 1: it works again, Now it doesn't You know, You're you're 538 00:28:03,040 --> 00:28:04,920 Speaker 1: throwing a parts cannon at this thing. And you haven't 539 00:28:04,960 --> 00:28:06,520 Speaker 1: hit that. You haven't hit the nail on the head yet. 540 00:28:06,680 --> 00:28:09,560 Speaker 3: Right, Well, when we could go, when I did, way, 541 00:28:09,760 --> 00:28:12,639 Speaker 3: he got in and he drew, he plugged in you know, 542 00:28:12,760 --> 00:28:16,280 Speaker 3: his scan tool, and we took off drive. But well, actually, 543 00:28:16,280 --> 00:28:18,720 Speaker 3: and I was writing shot and I said, here you play, 544 00:28:18,920 --> 00:28:21,600 Speaker 3: I said, I'll steer you just well, look at your 545 00:28:21,640 --> 00:28:22,639 Speaker 3: scan tool, you know. 546 00:28:23,320 --> 00:28:26,080 Speaker 1: Well you're looking at you're looking at or looking. 547 00:28:25,840 --> 00:28:29,080 Speaker 3: At you boy, he's looking at the scan right. 548 00:28:29,119 --> 00:28:33,840 Speaker 1: Well, somebody's looking for somebody is looking for the ability 549 00:28:33,880 --> 00:28:37,359 Speaker 1: to look at this and determine sensor values, sensor conditions 550 00:28:37,680 --> 00:28:39,680 Speaker 1: and what's going on. Go back and do those things 551 00:28:39,680 --> 00:28:41,560 Speaker 1: I talked about. Don come back to me with some 552 00:28:41,560 --> 00:28:43,760 Speaker 1: more information and then we can talk further. Eight five 553 00:28:43,920 --> 00:28:46,160 Speaker 1: five five six zero nine nine zero zero run eading 554 00:28:46,160 --> 00:29:01,280 Speaker 1: of the car doctor back right after this, let's uh, 555 00:29:01,520 --> 00:29:03,480 Speaker 1: let's go over and talk to David and Maine. David 556 00:29:03,600 --> 00:29:05,440 Speaker 1: Rong with Ronanny and the card doctor. How can I help? 557 00:29:07,200 --> 00:29:10,320 Speaker 4: Well, Ron, I have a situation with my car not 558 00:29:10,520 --> 00:29:13,920 Speaker 4: charging good, and I forget you would be the man 559 00:29:14,080 --> 00:29:16,520 Speaker 4: that would be able to tell me how. 560 00:29:16,400 --> 00:29:17,960 Speaker 1: To fix it, all right, let's see what you got. 561 00:29:20,200 --> 00:29:23,800 Speaker 4: It's a two thousand and six Buick Concern, right, and 562 00:29:28,160 --> 00:29:30,560 Speaker 4: you know, with a good battery and it charged, it 563 00:29:30,640 --> 00:29:34,800 Speaker 4: would uh sometimes not have enough juice to start it right, 564 00:29:34,960 --> 00:29:40,720 Speaker 4: And so typically I replaced the alternator and had another, 565 00:29:40,880 --> 00:29:44,160 Speaker 4: you know, the same problem. Right the next time, I 566 00:29:44,200 --> 00:29:48,320 Speaker 4: bought a new one, and a while later, a couple 567 00:29:48,320 --> 00:29:52,280 Speaker 4: of months later, that that went bad. So I figured 568 00:29:53,160 --> 00:29:55,800 Speaker 4: that was the problem. So I'm on my fourth alternator now. 569 00:29:56,440 --> 00:30:00,120 Speaker 4: But I've had it tested and the alternator seems to 570 00:30:00,160 --> 00:30:04,920 Speaker 4: be working right according to the scan tool, and the 571 00:30:04,960 --> 00:30:10,000 Speaker 4: battery seemed to be accurate. So there's something causing the 572 00:30:10,040 --> 00:30:13,000 Speaker 4: problem where it won't hold the charge on the battery, 573 00:30:13,880 --> 00:30:15,600 Speaker 4: and I can't figure it out. 574 00:30:15,880 --> 00:30:19,400 Speaker 1: Therefore, you ever, you ever ever get you ever get 575 00:30:19,400 --> 00:30:24,600 Speaker 1: an excessively high water bill at your house? David? No, No, really, 576 00:30:25,080 --> 00:30:27,200 Speaker 1: in all in all, in all your years, you've never 577 00:30:27,240 --> 00:30:28,920 Speaker 1: had a You've never had a case where the toilet 578 00:30:29,000 --> 00:30:33,200 Speaker 1: runs and it just doesn't seal. Yeah, yeah, And what 579 00:30:33,240 --> 00:30:34,600 Speaker 1: do you do? You go jiggle the handle and you 580 00:30:34,600 --> 00:30:36,640 Speaker 1: get the little rubber flap to seal inside the tank 581 00:30:36,720 --> 00:30:40,240 Speaker 1: and stops the water from leaking by right, right, right, well, 582 00:30:40,800 --> 00:30:43,200 Speaker 1: so you know, cars are kind of the same way, 583 00:30:43,280 --> 00:30:46,520 Speaker 1: not that they're a toilet, but it's you've got you've 584 00:30:46,560 --> 00:30:50,160 Speaker 1: got an electrical drain pulling the battery down. From the 585 00:30:50,200 --> 00:30:52,400 Speaker 1: sounds of it, it's got nothing to do with the alternator. 586 00:30:52,840 --> 00:30:54,959 Speaker 1: The only connection to the alternator is that it's attached 587 00:30:54,960 --> 00:30:55,800 Speaker 1: to the same vehicle. 588 00:30:57,080 --> 00:30:57,440 Speaker 4: Okay. 589 00:30:57,640 --> 00:31:00,120 Speaker 1: So the definition of insanity is keep doing the same 590 00:31:00,160 --> 00:31:02,400 Speaker 1: thing hoping for the same result and it never happens. 591 00:31:03,360 --> 00:31:07,520 Speaker 1: So what you need to do here is have somebody 592 00:31:07,600 --> 00:31:10,880 Speaker 1: do an electrical draw test. Let me ask you this question. 593 00:31:11,120 --> 00:31:13,520 Speaker 1: If you start the car, how often do you start 594 00:31:13,560 --> 00:31:17,800 Speaker 1: the car? How often do you drive this vehicle daily? Okay, 595 00:31:17,880 --> 00:31:20,440 Speaker 1: so you're telling me you start this car every day 596 00:31:20,440 --> 00:31:22,920 Speaker 1: over a seven day period, and you could get to 597 00:31:22,960 --> 00:31:25,800 Speaker 1: the fifth or sixth day at random, and the battery 598 00:31:25,880 --> 00:31:30,160 Speaker 1: is dead, right, okay? So batteries how old? 599 00:31:32,040 --> 00:31:32,640 Speaker 4: Two years? 600 00:31:32,680 --> 00:31:36,120 Speaker 1: All right? What makes you think? Well, how do you 601 00:31:36,120 --> 00:31:37,560 Speaker 1: know the battery is dead? What do you do to 602 00:31:37,600 --> 00:31:40,959 Speaker 1: start it? Do you jump it? Do you charge it? 603 00:31:43,480 --> 00:31:47,480 Speaker 1: I've done both, okay, and both of them right away, 604 00:31:47,560 --> 00:31:50,440 Speaker 1: no questions asked. The minuy you touch the cables, everything 605 00:31:50,520 --> 00:31:52,680 Speaker 1: lights up and off at fires. 606 00:31:52,960 --> 00:31:57,040 Speaker 4: Well, sometimes that happened. Sometimes I have to leave the 607 00:31:57,080 --> 00:32:00,280 Speaker 4: cables on it for four or five minutes before it'll. 608 00:32:02,080 --> 00:32:04,680 Speaker 1: Before you, before you hook up the cables, do you 609 00:32:04,720 --> 00:32:07,080 Speaker 1: happen to check battery voltage to see what it is 610 00:32:07,840 --> 00:32:08,400 Speaker 1: you have? 611 00:32:08,400 --> 00:32:09,120 Speaker 4: Haven't done that? 612 00:32:09,320 --> 00:32:10,880 Speaker 1: All right? I would like to know what that is? 613 00:32:11,160 --> 00:32:13,480 Speaker 1: All right? Just on the pretext. Do I really have 614 00:32:13,520 --> 00:32:15,800 Speaker 1: a dead battery? Do I have a bad connection at 615 00:32:15,800 --> 00:32:19,480 Speaker 1: the battery? Is that connection causing a resistance or contact 616 00:32:19,560 --> 00:32:21,560 Speaker 1: problem that makes this an intermittent? 617 00:32:22,640 --> 00:32:23,080 Speaker 3: All right? 618 00:32:23,480 --> 00:32:27,720 Speaker 1: Listen, this is a fairly straightforward problem to solve. We've 619 00:32:27,800 --> 00:32:30,720 Speaker 1: we've got to have We've got to have a good battery, 620 00:32:31,560 --> 00:32:35,000 Speaker 1: good connections on the positive and negative side at the battery, 621 00:32:35,600 --> 00:32:39,480 Speaker 1: and at the starter and at the ground lug down 622 00:32:39,480 --> 00:32:41,800 Speaker 1: where the negative cable attaches to either the frame or 623 00:32:41,800 --> 00:32:46,120 Speaker 1: the engine block. All right, if all of those are good, 624 00:32:46,200 --> 00:32:49,240 Speaker 1: and test it, and I want them, I want I 625 00:32:49,280 --> 00:32:51,960 Speaker 1: want a voltage drop test done. Then we're gonna have 626 00:32:51,960 --> 00:32:53,600 Speaker 1: to do a draw test. And if you sit tight, 627 00:32:53,640 --> 00:32:55,360 Speaker 1: I'll come back in two minutes and I'll explain a 628 00:32:55,440 --> 00:32:57,840 Speaker 1: draw test to you. Don't go anywhere. I'm ronning any 629 00:32:57,880 --> 00:33:13,400 Speaker 1: and the car doctor we'll be back right after this, David, 630 00:33:13,440 --> 00:33:18,960 Speaker 1: you're still there, David, David, there you go. All right, 631 00:33:19,040 --> 00:33:21,400 Speaker 1: in two minutes or less, I'm gonna tell you need 632 00:33:21,400 --> 00:33:24,040 Speaker 1: to do an electrical draw test on this vehicle. All right. 633 00:33:24,080 --> 00:33:25,680 Speaker 1: You're gonna tell me. You're gonna tell me you don't 634 00:33:25,680 --> 00:33:27,400 Speaker 1: see any lights on, you don't see anything on, you 635 00:33:27,400 --> 00:33:28,800 Speaker 1: don't hear anything on, And I'm gonna tell you it 636 00:33:28,800 --> 00:33:31,600 Speaker 1: doesn't matter. All right. Uh, you got a kitchen sink 637 00:33:31,600 --> 00:33:34,760 Speaker 1: in the house, Yeah, all right. If the water's off 638 00:33:35,400 --> 00:33:37,959 Speaker 1: and city water pressure is fifteen ps i, will make 639 00:33:38,000 --> 00:33:41,200 Speaker 1: it easy. It's twelve psi. What's the water pressure in 640 00:33:41,200 --> 00:33:42,680 Speaker 1: the kitchen sink with the faucet off? 641 00:33:43,800 --> 00:33:44,600 Speaker 4: Hopefully twelve? 642 00:33:44,640 --> 00:33:49,680 Speaker 1: Hopefully twelve? Well, well, no, no, behind that shut off valve, 643 00:33:49,680 --> 00:33:50,720 Speaker 1: do you have twelve psi? 644 00:33:52,000 --> 00:33:52,280 Speaker 4: Yeah? 645 00:33:52,400 --> 00:33:55,480 Speaker 1: Okay. That battery that sits in the car, nothing's on. 646 00:33:55,920 --> 00:33:58,200 Speaker 1: It's a twelve old battery. It's actually twelve and a half, 647 00:33:58,200 --> 00:34:00,000 Speaker 1: but for the sake of this conversation, we'll make it twelve. 648 00:34:00,680 --> 00:34:06,920 Speaker 1: All right, nothing's on. What's what's the voltage at that battery? Twelve? Right, 649 00:34:07,160 --> 00:34:09,680 Speaker 1: voltage and pressure are the same. It's always there. It's 650 00:34:09,680 --> 00:34:13,600 Speaker 1: a constant Okay. If you open up the faucet and 651 00:34:13,640 --> 00:34:16,040 Speaker 1: you fill an eight ounce cup in thirty seconds, we 652 00:34:16,080 --> 00:34:20,480 Speaker 1: figure it out. That's x amount of volume. Right. If 653 00:34:20,480 --> 00:34:24,840 Speaker 1: a bulb comes on and it draws out of that battery, 654 00:34:25,000 --> 00:34:28,160 Speaker 1: it's x amount of volume. Somebody needs to do a 655 00:34:28,280 --> 00:34:30,839 Speaker 1: draw test. It's done by hooking up a digital vault 656 00:34:30,880 --> 00:34:34,719 Speaker 1: homemeter and millim draw test. That system can have more 657 00:34:34,760 --> 00:34:38,799 Speaker 1: than fifty millims of draw after a one hour time 658 00:34:38,840 --> 00:34:41,279 Speaker 1: period of sitting down and waiting, do a draw test 659 00:34:41,280 --> 00:34:43,040 Speaker 1: to that vehicle. Come back and tell me what you find. 660 00:34:43,040 --> 00:34:44,839 Speaker 1: We'll talk some more. I'm running any in the card 661 00:34:44,840 --> 00:34:48,440 Speaker 1: doctor until the next time. Good mechanics aren't expensive, they're priceless. 662 00:34:48,719 --> 00:34:58,520 Speaker 1: See you
