1 00:00:02,160 --> 00:00:03,920 Speaker 1: Ron Andanian. You know I always look at us if 2 00:00:03,960 --> 00:00:06,200 Speaker 1: you put me in the car, well, I notice the problem? 3 00:00:06,240 --> 00:00:08,200 Speaker 1: Does it take something special? You know? What do I 4 00:00:08,200 --> 00:00:10,520 Speaker 1: have to? You know, stand on my head, spickwood nickels 5 00:00:10,520 --> 00:00:29,160 Speaker 1: and rub my belly button counterclockwise and chanting something the 6 00:00:29,200 --> 00:00:32,240 Speaker 1: car doctor. Do you still have the old back door? 7 00:00:32,320 --> 00:00:35,400 Speaker 1: Do you still have the old canister? Perge men? Oh? Yeah, okay, 8 00:00:35,479 --> 00:00:38,040 Speaker 1: did you try blowing through it? I did not try blowing. 9 00:00:38,640 --> 00:00:42,240 Speaker 1: Welcome to the radio home of Ron Andanian the Car Doctor, 10 00:00:42,560 --> 00:00:46,680 Speaker 1: since this is where car owners the world over turned 11 00:00:46,720 --> 00:00:50,800 Speaker 1: to for their definitive opinion on automotive repair. If your 12 00:00:50,880 --> 00:00:53,720 Speaker 1: mechanics giving you a busy signal, pick up the phone 13 00:00:53,880 --> 00:00:57,200 Speaker 1: and call in the garage. Orders are open, but I 14 00:00:57,200 --> 00:00:59,480 Speaker 1: am here to take your calls at eight five five 15 00:00:59,800 --> 00:01:07,640 Speaker 1: six and now running. Where do I start today? Um? 16 00:01:07,680 --> 00:01:09,520 Speaker 1: You know, I've got my little cheat sheet in front 17 00:01:09,520 --> 00:01:10,880 Speaker 1: of me that I write during the week at the shop. 18 00:01:10,920 --> 00:01:13,360 Speaker 1: I've got my show day copy paper that I wrote, 19 00:01:13,360 --> 00:01:15,560 Speaker 1: and I'm looking at my notes and the first one, 20 00:01:15,720 --> 00:01:18,040 Speaker 1: the first listing on whatever day this was. I think 21 00:01:18,040 --> 00:01:20,040 Speaker 1: it was from the late the week before, but I 22 00:01:20,080 --> 00:01:21,560 Speaker 1: failed to mention it last week and I wanted to 23 00:01:21,560 --> 00:01:23,360 Speaker 1: talk about it because I thought it was a good repair. 24 00:01:23,520 --> 00:01:27,160 Speaker 1: It was a two thousand three D forty International, you know, 25 00:01:27,200 --> 00:01:29,840 Speaker 1: one of those cab over big medium truck jobs. We 26 00:01:29,880 --> 00:01:31,560 Speaker 1: had to work on the blower motor diet into a 27 00:01:31,560 --> 00:01:34,720 Speaker 1: blowermower diagnosis that um, you know, nobody else could do. 28 00:01:34,800 --> 00:01:37,400 Speaker 1: And you know, it was just kind of an interesting repair. 29 00:01:37,480 --> 00:01:39,480 Speaker 1: Or do I want to talk about how much money 30 00:01:39,520 --> 00:01:41,920 Speaker 1: do you put into a to fifty? That's what my 31 00:01:42,000 --> 00:01:44,880 Speaker 1: notes say. I wrote how much money into a to fifty? 32 00:01:44,880 --> 00:01:47,279 Speaker 1: I know the vehicle I'm thinking about because we finished 33 00:01:47,280 --> 00:01:49,400 Speaker 1: it on Thursday this week because we were off on Friday. 34 00:01:49,400 --> 00:01:51,960 Speaker 1: We take the first Friday off. We're like that, we're 35 00:01:52,000 --> 00:01:55,080 Speaker 1: kind of tired, and um, my last heading for the week, 36 00:01:55,120 --> 00:01:57,000 Speaker 1: my last entry into my journal this week was my 37 00:01:57,040 --> 00:02:00,840 Speaker 1: broken plow truck, my snow plow truck. So you know, 38 00:02:02,320 --> 00:02:05,440 Speaker 1: let's talk about the International. I think that's a good story. 39 00:02:05,680 --> 00:02:07,240 Speaker 1: They're all good stories, but I think we'll start there 40 00:02:07,280 --> 00:02:08,920 Speaker 1: because it's a leftover from last week. I want to 41 00:02:08,919 --> 00:02:12,320 Speaker 1: get cleaned up. So my friend Kenny owns the welding 42 00:02:12,360 --> 00:02:16,120 Speaker 1: shop up next town over and he Kenny's a great welder, 43 00:02:16,160 --> 00:02:18,600 Speaker 1: former body man, great welder. He's just a great all 44 00:02:18,639 --> 00:02:20,760 Speaker 1: around fabricator. He can do a lot of things, and 45 00:02:21,080 --> 00:02:23,079 Speaker 1: to say he's just a welder would be a discredit 46 00:02:23,120 --> 00:02:26,800 Speaker 1: to him because he's a real sharp cat. Well, he 47 00:02:26,919 --> 00:02:31,519 Speaker 1: had this oh three D forty International, which is kind 48 00:02:31,520 --> 00:02:34,400 Speaker 1: of like one of those medium truck rack body things 49 00:02:34,400 --> 00:02:37,040 Speaker 1: with the cab overs, you know, the nose tilts forward 50 00:02:37,040 --> 00:02:39,200 Speaker 1: when you open it up. It's that size, and he's 51 00:02:39,240 --> 00:02:41,440 Speaker 1: got all his welding equipment on it, and these guys 52 00:02:41,440 --> 00:02:43,720 Speaker 1: are driving around and they're called the blower motor doesn't work, 53 00:02:43,760 --> 00:02:46,080 Speaker 1: and I guess you know a bunch of people have 54 00:02:46,160 --> 00:02:47,960 Speaker 1: worked on it and poked at it and all sorts 55 00:02:47,960 --> 00:02:50,280 Speaker 1: of weird things. And you kind of know that when 56 00:02:50,280 --> 00:02:52,280 Speaker 1: you when you get the vehicle and you go to 57 00:02:52,320 --> 00:02:55,240 Speaker 1: the fuse box that you that you have to open 58 00:02:55,360 --> 00:02:58,280 Speaker 1: up and it's held on by sheet metal screws instead 59 00:02:58,320 --> 00:03:00,760 Speaker 1: of you know, the factory clips. It's like somebody's been 60 00:03:00,760 --> 00:03:02,359 Speaker 1: taking this thing apart, and they took it apart so 61 00:03:02,360 --> 00:03:04,800 Speaker 1: many times they actually broke away. It mounts to cover 62 00:03:04,880 --> 00:03:06,400 Speaker 1: for the fuse box over on the right side of 63 00:03:06,400 --> 00:03:10,240 Speaker 1: the dish. So fortunately I went into my Mitchell one account, 64 00:03:10,240 --> 00:03:13,200 Speaker 1: and Mitchell one provided me with wiring diagrams for a 65 00:03:13,840 --> 00:03:16,320 Speaker 1: uh two thousand three, two thousand three or two thousand two. 66 00:03:16,320 --> 00:03:17,720 Speaker 1: Maybe it was a two thousand two. It doesn't matter. 67 00:03:17,760 --> 00:03:20,000 Speaker 1: It's all the same. That the neat thing about the trucks, 68 00:03:20,040 --> 00:03:23,239 Speaker 1: like the four thousand series Internationals that we're talking about 69 00:03:23,320 --> 00:03:25,919 Speaker 1: is the technologies from like nineteen sixty two. It hasn't 70 00:03:26,000 --> 00:03:28,640 Speaker 1: changed the whole heck of a lot, especially when it 71 00:03:28,680 --> 00:03:33,400 Speaker 1: comes to wiring their their big heavy duty vehicles. So 72 00:03:33,440 --> 00:03:35,760 Speaker 1: I went through the wiring diagram courtesy of folks at 73 00:03:35,760 --> 00:03:39,520 Speaker 1: Mitchell one, and their wiring diagram was spot on all right. 74 00:03:40,160 --> 00:03:45,600 Speaker 1: The problem was, there's sixteen wires in this circuit that 75 00:03:45,640 --> 00:03:49,640 Speaker 1: we're worried about. Thirteen of them are green, I mean 76 00:03:50,280 --> 00:03:55,360 Speaker 1: green like no shades, no variation. And what they do, 77 00:03:55,480 --> 00:03:58,320 Speaker 1: which is really makes you scratch your head. But then again, 78 00:03:58,320 --> 00:04:01,960 Speaker 1: maybe it really is nineteen sixty three technology. They identify 79 00:04:02,160 --> 00:04:06,800 Speaker 1: each wire by printing the number of the circuit. So 80 00:04:06,880 --> 00:04:09,040 Speaker 1: for example, and I pulled the wiring diagram and I 81 00:04:09,080 --> 00:04:11,880 Speaker 1: brought it with me from the shop today. So Circuit 82 00:04:12,080 --> 00:04:14,960 Speaker 1: A seventy five C, which is the light green wire 83 00:04:15,000 --> 00:04:16,520 Speaker 1: that goes to pen A. One of the heater control 84 00:04:16,600 --> 00:04:20,720 Speaker 1: module comes off of fuse number six H five AM 85 00:04:20,760 --> 00:04:24,480 Speaker 1: fuse that provides power to the heater control head off 86 00:04:24,520 --> 00:04:27,600 Speaker 1: the five ault ignition feed. Then there's circuit A seventy 87 00:04:27,640 --> 00:04:30,120 Speaker 1: three B in a seventy seven and a seventy five 88 00:04:30,200 --> 00:04:33,279 Speaker 1: A and so on, and every wire has got a 89 00:04:33,279 --> 00:04:37,640 Speaker 1: wiring circuit printed right on it. I went to the 90 00:04:37,640 --> 00:04:40,240 Speaker 1: control head, you know, because I've got to I've gotta 91 00:04:40,240 --> 00:04:41,920 Speaker 1: break this thing down, and how fast can I get 92 00:04:41,920 --> 00:04:43,320 Speaker 1: to the problem and solve it. I went to the 93 00:04:43,320 --> 00:04:47,920 Speaker 1: control head and I xed out one, two, three, four, five, six, seven, 94 00:04:48,000 --> 00:04:51,520 Speaker 1: eight wires that had no purpose or no substance that 95 00:04:51,520 --> 00:04:53,560 Speaker 1: would prevent the blower motor from working. They were in 96 00:04:53,600 --> 00:04:57,560 Speaker 1: no particular order. A C request the diagnostic wire, which 97 00:04:57,600 --> 00:04:59,960 Speaker 1: runs over to a diagnostic plug on the fender well 98 00:05:00,040 --> 00:05:02,240 Speaker 1: that they can plug some sort of diagnostic tool into 99 00:05:02,240 --> 00:05:08,000 Speaker 1: should they want to. Um the the recirculation motor control positive, 100 00:05:08,000 --> 00:05:11,560 Speaker 1: recirculation motor control negative mode, or motor positive and negative 101 00:05:11,560 --> 00:05:15,440 Speaker 1: intim sense door motor negative positive. You know, we they're 102 00:05:15,440 --> 00:05:17,240 Speaker 1: not important to us at this point. We need to 103 00:05:17,240 --> 00:05:20,320 Speaker 1: get a blower motor that runs. So I went to 104 00:05:20,360 --> 00:05:22,160 Speaker 1: the control head, went to the blower motor, pulled the 105 00:05:22,160 --> 00:05:23,920 Speaker 1: blower motor out. After I took out the four sheet 106 00:05:23,960 --> 00:05:27,240 Speaker 1: metal screws holding the fuse cover box on and pop 107 00:05:27,320 --> 00:05:29,039 Speaker 1: the control head out of the dish, which was four 108 00:05:29,040 --> 00:05:31,080 Speaker 1: simple screws, and out it came. And now I'm at 109 00:05:31,120 --> 00:05:34,400 Speaker 1: both ends of the circuit. I went to the fuse box, 110 00:05:34,800 --> 00:05:36,680 Speaker 1: and I went to the thirty m fuse that was 111 00:05:36,720 --> 00:05:40,039 Speaker 1: supposed to provide power to the circuit, and it was missing. 112 00:05:41,279 --> 00:05:45,800 Speaker 1: And I went, wait a minute, fuse number four. It 113 00:05:45,839 --> 00:05:49,239 Speaker 1: wasn't even in the fuse box. I talked to Kenny Canny. 114 00:05:49,240 --> 00:05:52,040 Speaker 1: Anybody work on this? He said no? I said, did 115 00:05:52,040 --> 00:05:53,839 Speaker 1: the blower ever work when you bought it? Because he 116 00:05:53,839 --> 00:05:56,800 Speaker 1: bought it used? I think. So, you know, sometimes your 117 00:05:56,800 --> 00:05:59,080 Speaker 1: buddies just make you more crazy than they need to write. 118 00:05:59,120 --> 00:06:01,360 Speaker 1: It's like I'm getting any information out of this guy, 119 00:06:01,360 --> 00:06:03,680 Speaker 1: so I've got to assume the worst. So he's a 120 00:06:03,680 --> 00:06:06,600 Speaker 1: good welder, though I love him for his welming. So 121 00:06:07,160 --> 00:06:09,000 Speaker 1: put a thirty m fuse in where it was supposed 122 00:06:09,000 --> 00:06:11,280 Speaker 1: to be verified that was the right circuit, went down 123 00:06:11,360 --> 00:06:13,159 Speaker 1: to the blower motor, where I didn't have power. I 124 00:06:13,160 --> 00:06:15,560 Speaker 1: still didn't have power. Oh wait, and then I did 125 00:06:15,680 --> 00:06:17,880 Speaker 1: because it was a bad connection at the fuse box 126 00:06:18,240 --> 00:06:20,120 Speaker 1: where the fuse was supposed to go in. So maybe 127 00:06:20,200 --> 00:06:23,239 Speaker 1: somebody previous to me. I went to work on the fuse, 128 00:06:23,240 --> 00:06:25,200 Speaker 1: the phone rang, they forgotten. They put it back together, 129 00:06:25,240 --> 00:06:28,039 Speaker 1: and you know, I don't know. You can never assume 130 00:06:28,040 --> 00:06:30,520 Speaker 1: in diagnosis. That's the problem. You've got to do things 131 00:06:30,520 --> 00:06:34,640 Speaker 1: step by step. It's painstaking at times. So with the 132 00:06:34,680 --> 00:06:36,400 Speaker 1: thirty m fuse in the fuse box where it was 133 00:06:36,400 --> 00:06:38,159 Speaker 1: supposed to be, I now had power on the main 134 00:06:38,240 --> 00:06:41,520 Speaker 1: leg to the blower motor, but the blower motor control 135 00:06:41,600 --> 00:06:44,760 Speaker 1: as far as speeds, we're all done on the negative side. 136 00:06:44,760 --> 00:06:47,719 Speaker 1: They were all done by changing things on the negative 137 00:06:47,720 --> 00:06:50,040 Speaker 1: control side going to the blowers. So they were stepping 138 00:06:50,040 --> 00:06:53,840 Speaker 1: it down through a resistor. The resistors are common to fail. 139 00:06:54,440 --> 00:06:57,320 Speaker 1: I know that. They're also very expensive there three hundred bucks, 140 00:06:57,320 --> 00:06:59,039 Speaker 1: and you know me, I'm not about to start throwing 141 00:06:59,040 --> 00:07:01,320 Speaker 1: parts at something. So I went through and I broke 142 00:07:01,320 --> 00:07:02,960 Speaker 1: it down, and I kept going back to my pin 143 00:07:03,000 --> 00:07:04,920 Speaker 1: out at the at the heat or control head. As 144 00:07:04,920 --> 00:07:09,000 Speaker 1: far as what does each individual wire do? I came 145 00:07:09,040 --> 00:07:12,440 Speaker 1: to a conclusion that the white wire the one white 146 00:07:12,480 --> 00:07:18,680 Speaker 1: wire in the midst of the sixteen greens. All right, Uh, 147 00:07:18,760 --> 00:07:20,880 Speaker 1: I had ground from the control head, but I did 148 00:07:20,920 --> 00:07:24,760 Speaker 1: not have ground on the opposite leg coming from the 149 00:07:24,800 --> 00:07:29,480 Speaker 1: blower motor resistor. I also didn't have the five bold 150 00:07:29,560 --> 00:07:31,560 Speaker 1: signal I was supposed to have coming from the control 151 00:07:31,640 --> 00:07:35,680 Speaker 1: head over to the resistor to pull the leg down 152 00:07:35,720 --> 00:07:40,360 Speaker 1: and run the motor. Huh. Followed it out, came to 153 00:07:40,400 --> 00:07:44,080 Speaker 1: the connector in the dash. Now, you know, the the 154 00:07:44,160 --> 00:07:46,640 Speaker 1: hard thing is, You've got to find this connector because 155 00:07:46,640 --> 00:07:49,840 Speaker 1: wiring diagrams in general for these trucks isn't great. And 156 00:07:49,880 --> 00:07:51,680 Speaker 1: I was fortunate that it was right next to the 157 00:07:51,720 --> 00:07:54,600 Speaker 1: blower case. Mitchell told me what colors I was looking for. 158 00:07:54,760 --> 00:07:57,360 Speaker 1: Mitchell one was right on the money. All right. I 159 00:07:57,440 --> 00:07:59,680 Speaker 1: found my wire colors, and sure enough, the minute I 160 00:07:59,720 --> 00:08:02,600 Speaker 1: touched the connector. And I always leave a meter hooked 161 00:08:02,680 --> 00:08:04,360 Speaker 1: up to the object of whatever it is I'm testing. 162 00:08:04,400 --> 00:08:05,960 Speaker 1: As soon as I touched the connector, I heard the 163 00:08:05,960 --> 00:08:08,720 Speaker 1: audible go off on the meter. It chirped, telling me 164 00:08:08,760 --> 00:08:10,560 Speaker 1: all of a sudden, I had voltage. I looked down, 165 00:08:11,040 --> 00:08:14,440 Speaker 1: I looked over and there it was something in this 166 00:08:14,480 --> 00:08:21,120 Speaker 1: connector took the connector apart, corroded, melted, just damaged all right. 167 00:08:21,400 --> 00:08:24,960 Speaker 1: Total time to diagnose forty two minutes, And that accounts 168 00:08:25,000 --> 00:08:26,960 Speaker 1: for the taking the screws out and talking to Kenny 169 00:08:27,000 --> 00:08:29,000 Speaker 1: and finding out there was a missing fuse and a 170 00:08:29,000 --> 00:08:31,600 Speaker 1: couple other things that have been monkeyed around with in 171 00:08:32,200 --> 00:08:37,120 Speaker 1: terms of failure. And the point becomes that anything can 172 00:08:37,160 --> 00:08:40,760 Speaker 1: get fixed. I ended up splicing around that connector. I 173 00:08:40,760 --> 00:08:43,320 Speaker 1: cut it out completely, and I saw it in some 174 00:08:44,240 --> 00:08:48,439 Speaker 1: proper gage heat shrink male and female connectors, making sure 175 00:08:48,480 --> 00:08:50,800 Speaker 1: to gauge them, you know, flip them so you can't 176 00:08:50,800 --> 00:08:53,520 Speaker 1: plug it in backwards. If anybody ever had to multi 177 00:08:53,559 --> 00:08:56,320 Speaker 1: plug on something and take the blower motor assembly out, 178 00:08:56,679 --> 00:08:59,120 Speaker 1: you know, a male and a female on one side, 179 00:08:59,120 --> 00:09:01,480 Speaker 1: a male and a female on the other opposite, so 180 00:09:01,559 --> 00:09:04,440 Speaker 1: you can't plug it in wrong. And this truck was fixed. 181 00:09:05,640 --> 00:09:09,400 Speaker 1: Anything can be diagnosed. It's not always easy, it's it's 182 00:09:09,480 --> 00:09:12,719 Speaker 1: it's not always what you would say enjoyable. Um. It 183 00:09:12,760 --> 00:09:14,480 Speaker 1: always is a challenge. And I think that's some of 184 00:09:14,520 --> 00:09:15,920 Speaker 1: the things that you look for when you're trying to 185 00:09:15,960 --> 00:09:20,240 Speaker 1: diagnose something. And I took a lot of steps. You know, 186 00:09:20,480 --> 00:09:23,079 Speaker 1: one after the other after the other. I never went 187 00:09:23,160 --> 00:09:25,760 Speaker 1: chasing what was what was bad. I knew the blower 188 00:09:25,800 --> 00:09:27,640 Speaker 1: didn't work, and I proved that in the first thirty 189 00:09:27,640 --> 00:09:30,760 Speaker 1: seconds I turned the switch on. It didn't work. I 190 00:09:30,800 --> 00:09:33,920 Speaker 1: went after what was good. When I started to knock 191 00:09:33,960 --> 00:09:36,440 Speaker 1: down wires of this works, this works, This doesn't matter, 192 00:09:36,480 --> 00:09:38,719 Speaker 1: this doesn't matter, this doesn't matter. And if you can 193 00:09:38,760 --> 00:09:40,599 Speaker 1: see the wiring diagram I've got in front of me, 194 00:09:40,640 --> 00:09:42,680 Speaker 1: you'll see I actually exed out the wire. I don't 195 00:09:42,720 --> 00:09:44,400 Speaker 1: care about that. I don't care about that. I don't 196 00:09:44,440 --> 00:09:46,440 Speaker 1: care about that. And then I circled the ones that 197 00:09:46,480 --> 00:09:48,440 Speaker 1: were important. And once I was able to zero in 198 00:09:48,520 --> 00:09:50,960 Speaker 1: on the ones that were important, it got me to 199 00:09:50,960 --> 00:09:54,160 Speaker 1: the positive conclusion. It did in less than forty five minutes. 200 00:09:54,679 --> 00:09:57,559 Speaker 1: So keep that in mind. When you're diagnosing. You've got 201 00:09:57,559 --> 00:10:00,280 Speaker 1: to have a wiring diagram. You've got to understand the 202 00:10:00,320 --> 00:10:04,319 Speaker 1: components you're working on, how they work. It can't be 203 00:10:04,360 --> 00:10:06,920 Speaker 1: based on well, you know the last seven of these 204 00:10:06,920 --> 00:10:08,400 Speaker 1: we had, this is what was wrong with it. Or 205 00:10:08,480 --> 00:10:10,319 Speaker 1: my brother Bob had one of these ten years ago 206 00:10:10,440 --> 00:10:12,360 Speaker 1: and this is what was wrong. It's got to be 207 00:10:12,400 --> 00:10:15,280 Speaker 1: based on what I always tell you. Tell me what's good. 208 00:10:15,559 --> 00:10:19,560 Speaker 1: I'll tell you what's bad. Zero zero is the phone 209 00:10:19,640 --> 00:10:23,240 Speaker 1: number again, eight five five five zero nine zero zeros 210 00:10:23,240 --> 00:10:25,080 Speaker 1: the phone number. Give us a call. I'm running ending 211 00:10:25,120 --> 00:10:37,079 Speaker 1: the car doctor. I'll be back right after this. Whether 212 00:10:37,120 --> 00:10:40,280 Speaker 1: it's a little red Corvette or you go, you've come 213 00:10:40,320 --> 00:10:42,480 Speaker 1: to the right place to get that car fixed. Ron 214 00:10:42,559 --> 00:10:45,080 Speaker 1: and Nay in the car doctor. Eight five five five 215 00:10:45,440 --> 00:10:50,040 Speaker 1: zero zero zero. Now back to ron recent article. And 216 00:10:50,040 --> 00:10:53,560 Speaker 1: by the way, before I forget, if anybody has curiosity 217 00:10:53,840 --> 00:10:55,920 Speaker 1: Mitchell one dot com if you're looking to look into 218 00:10:55,920 --> 00:10:58,280 Speaker 1: Mitchell product and uh, if you're a repair shop and 219 00:10:58,280 --> 00:11:00,920 Speaker 1: you're looking for some medium truck repair information as well, 220 00:11:00,920 --> 00:11:02,920 Speaker 1: because every once in a while you need that, right 221 00:11:03,000 --> 00:11:05,480 Speaker 1: it's just somebody your buddy brings you a welding truck 222 00:11:05,480 --> 00:11:07,120 Speaker 1: and you have to fix it. You need a wiring 223 00:11:07,120 --> 00:11:10,880 Speaker 1: diagram Mitchell one. Folks at Mitchell one dot com. Uh, 224 00:11:10,960 --> 00:11:12,720 Speaker 1: somebody handed me an article this week, and I wanted 225 00:11:12,760 --> 00:11:14,240 Speaker 1: to go over with you here on air because we 226 00:11:14,240 --> 00:11:17,160 Speaker 1: were talking about this not too long ago, you and 227 00:11:17,200 --> 00:11:20,280 Speaker 1: I during our course of conversation about electric vehicles. It 228 00:11:20,320 --> 00:11:22,719 Speaker 1: talks about the state of Illinois, how the state of 229 00:11:22,760 --> 00:11:26,400 Speaker 1: Illinois is taking a look at the gasoline tax, or 230 00:11:26,440 --> 00:11:28,600 Speaker 1: the lack of gasoline tax. I guess is a better 231 00:11:28,600 --> 00:11:31,600 Speaker 1: way to put it on the EV vehicle. So in 232 00:11:31,640 --> 00:11:34,599 Speaker 1: twenty the article starts out, the state legislature approved the 233 00:11:34,640 --> 00:11:38,280 Speaker 1: forty five billion dollar transportation bill that double the state 234 00:11:38,360 --> 00:11:40,960 Speaker 1: gas tax to help pay for improvements to infrastructure. But 235 00:11:41,320 --> 00:11:43,960 Speaker 1: since electric vehicle owners don't visit the gas pump, the 236 00:11:44,040 --> 00:11:46,040 Speaker 1: state passed a law to put a one hundred dollar 237 00:11:46,120 --> 00:11:49,280 Speaker 1: yearly tax on evs, adding it onto the annual license 238 00:11:49,280 --> 00:11:53,160 Speaker 1: plate renewal that went to effect in July of the 239 00:11:53,240 --> 00:11:57,280 Speaker 1: feet came as an alternative after a Representative Martin Sandoval, 240 00:11:57,360 --> 00:11:59,959 Speaker 1: he's a Democrat out of Chicago, proposed a one thousand 241 00:12:00,000 --> 00:12:03,440 Speaker 1: dollar a year tax on electric vehicles. According to Electric, 242 00:12:04,120 --> 00:12:06,760 Speaker 1: if energy was taxed at the same rate as gasoline, 243 00:12:06,800 --> 00:12:08,760 Speaker 1: a Tesla Model three, which is rated at a hundred 244 00:12:08,760 --> 00:12:11,880 Speaker 1: and thirty miles per gallon equivalent, would have to drive 245 00:12:11,920 --> 00:12:13,559 Speaker 1: thirty four thousand miles a year to make up for 246 00:12:13,559 --> 00:12:17,440 Speaker 1: a hundred gas tax my EV. The article goes on 247 00:12:17,520 --> 00:12:19,440 Speaker 1: to say report that the owner of an internal combustion 248 00:12:19,480 --> 00:12:22,160 Speaker 1: engine gets twenty four miles per gallon and drives fifteen 249 00:12:22,200 --> 00:12:24,360 Speaker 1: thousand annual miles would pay around two d and thirty 250 00:12:24,400 --> 00:12:27,640 Speaker 1: seven dollars a year in taxes at the pump. Electric 251 00:12:27,760 --> 00:12:29,680 Speaker 1: also calculated, and this is the part I wanted you 252 00:12:29,679 --> 00:12:33,600 Speaker 1: guys to hear. Electric also calculated that the average vehicle 253 00:12:33,640 --> 00:12:37,600 Speaker 1: miles traveled per year by the average Illinois driver were 254 00:12:37,640 --> 00:12:41,560 Speaker 1: around eight thousand. So that means that we're not going 255 00:12:41,600 --> 00:12:43,760 Speaker 1: to drive the thirty four thousand miles that you're being 256 00:12:43,800 --> 00:12:46,360 Speaker 1: taxed at. You're gonna drive eight thousand. As the outomotive 257 00:12:46,360 --> 00:12:49,600 Speaker 1: industry makes a shift toward electric vehicles, the Illinois Department 258 00:12:49,600 --> 00:12:54,959 Speaker 1: of Transportation says it is considering taxing EV charging stations. Well, 259 00:12:55,000 --> 00:12:57,480 Speaker 1: we knew that was coming right, in an effort to 260 00:12:57,559 --> 00:13:01,080 Speaker 1: offset the projected revenue laws from fuel sales. According to 261 00:13:01,800 --> 00:13:06,439 Speaker 1: Department Transportation Secretary for Illinois Secretary Omar Osmond, the department 262 00:13:06,440 --> 00:13:08,840 Speaker 1: is looking at several ways to tax EV drivers to 263 00:13:08,920 --> 00:13:11,560 Speaker 1: make up for projected shortfalls once more evs go on 264 00:13:11,600 --> 00:13:13,600 Speaker 1: the road at some point in time down the road, 265 00:13:13,640 --> 00:13:15,959 Speaker 1: maybe gradually, as the electric vehicle takes over, someone's got 266 00:13:15,960 --> 00:13:18,400 Speaker 1: to come up with a different mechanism force, they said 267 00:13:18,440 --> 00:13:21,320 Speaker 1: at the meeting of the Illinois News Broadcasters Association. According 268 00:13:21,360 --> 00:13:26,160 Speaker 1: to w c bu UM, one proposal is including tax 269 00:13:26,200 --> 00:13:28,199 Speaker 1: at the charging station or at the dealership when a 270 00:13:28,280 --> 00:13:32,559 Speaker 1: vehicle is purchased. Nineteen states currently in total charge extra 271 00:13:32,600 --> 00:13:35,320 Speaker 1: fees to electric vehicle owners, according to the National Conference 272 00:13:35,320 --> 00:13:38,600 Speaker 1: of State Legislatures, raging from fifty hundred and fifty dollars. 273 00:13:39,400 --> 00:13:41,520 Speaker 1: Remember the conversation we had about what will they do 274 00:13:41,559 --> 00:13:45,320 Speaker 1: about no gas tax? Well, there it is. They're gonna 275 00:13:45,320 --> 00:13:47,360 Speaker 1: they're gonna tax you on registration. They're gonna attack you 276 00:13:47,400 --> 00:13:50,480 Speaker 1: to charge it. They're going to uh, you know, tax 277 00:13:50,559 --> 00:13:53,040 Speaker 1: you a bunch of different things as you continue or 278 00:13:53,040 --> 00:13:56,559 Speaker 1: trying to operate the vehicle. So just not making it up, 279 00:13:56,600 --> 00:13:58,840 Speaker 1: just reporting the news as it occurs, because it's important 280 00:13:58,840 --> 00:14:00,400 Speaker 1: you guys have all the facts and runt of you. 281 00:14:00,679 --> 00:14:02,640 Speaker 1: Let's go over to Ray in Michigan. O three Lincoln 282 00:14:02,679 --> 00:14:05,240 Speaker 1: town car and some rumbling going on. Ray. Welcome to 283 00:14:05,280 --> 00:14:09,120 Speaker 1: the car, doctor, sir. How can I help? Yes, sir, 284 00:14:09,440 --> 00:14:14,040 Speaker 1: I have a all three h Lincoln town car that's 285 00:14:14,400 --> 00:14:20,400 Speaker 1: making a rumbling noise. One about forty goes shifted up 286 00:14:20,400 --> 00:14:25,960 Speaker 1: into high gear overdrive. But it's only doing it on 287 00:14:26,120 --> 00:14:30,880 Speaker 1: occasion and That's why I was kind of curious about 288 00:14:31,760 --> 00:14:35,960 Speaker 1: does that sound like a transmission failure, intimate or do 289 00:14:36,000 --> 00:14:37,920 Speaker 1: you think that car may go for quite a while 290 00:14:38,040 --> 00:14:40,720 Speaker 1: like that? Well it could. It could be the beginnings 291 00:14:40,720 --> 00:14:43,680 Speaker 1: of a converter chatter. If you tap the brake pedal, 292 00:14:43,760 --> 00:14:49,440 Speaker 1: does the problem go away? Uh? Actually, never tried that, 293 00:14:49,720 --> 00:14:52,720 Speaker 1: because when you when you tap the brake and then 294 00:14:52,760 --> 00:14:55,280 Speaker 1: reapply to gas, what you've done is you've you've knocked 295 00:14:55,280 --> 00:14:58,040 Speaker 1: the converter off. As we say, so, there's a couple 296 00:14:58,040 --> 00:15:03,280 Speaker 1: of different variations are worms of transmission operation for these vehicles, alright, 297 00:15:03,320 --> 00:15:07,600 Speaker 1: depending upon the transports. Here's here's the generic runout. However, 298 00:15:07,640 --> 00:15:10,800 Speaker 1: many forward speeds you have three, four or five whatever 299 00:15:10,800 --> 00:15:13,720 Speaker 1: it is, and at any given time, in any one 300 00:15:13,720 --> 00:15:16,480 Speaker 1: of those speeds, the transmission has the ability to go 301 00:15:16,520 --> 00:15:21,840 Speaker 1: into a overdrive all right, which will reduce the engine 302 00:15:21,920 --> 00:15:24,760 Speaker 1: rpm required based on vehicle load, whether or not it's 303 00:15:24,800 --> 00:15:28,080 Speaker 1: just into overdrive. And then two it will go into 304 00:15:28,400 --> 00:15:32,840 Speaker 1: lock up, all right. Think of think of to think 305 00:15:32,840 --> 00:15:36,600 Speaker 1: of think of two house fans, right if you took 306 00:15:36,720 --> 00:15:38,440 Speaker 1: if you took one house fan and put it in 307 00:15:38,520 --> 00:15:40,440 Speaker 1: front of the other one and turned one of them 308 00:15:40,440 --> 00:15:46,320 Speaker 1: on it would it would drive the other fan right, Okay, 309 00:15:46,960 --> 00:15:50,720 Speaker 1: so not the most efficient way, but that's the way 310 00:15:50,720 --> 00:15:53,320 Speaker 1: a torque converter works. That's basically what what a torqu 311 00:15:53,320 --> 00:15:56,480 Speaker 1: converter is. Inside of a transmission, one side is fixed, 312 00:15:56,480 --> 00:15:59,800 Speaker 1: the other side spends based on how hard the fan 313 00:16:00,040 --> 00:16:03,080 Speaker 1: laid on the other side is pushing. Well, if we 314 00:16:03,120 --> 00:16:06,240 Speaker 1: want to have a direct mechanical lock, we're now going 315 00:16:06,280 --> 00:16:08,840 Speaker 1: to figure out a way to have those fan blades 316 00:16:08,920 --> 00:16:13,040 Speaker 1: touch and have a mechanical connection between the engine and 317 00:16:13,080 --> 00:16:18,800 Speaker 1: the transmission. All right, So what we do with this, 318 00:16:19,080 --> 00:16:21,280 Speaker 1: Well we do this with something called it's it's basically 319 00:16:21,280 --> 00:16:25,160 Speaker 1: a centrifugal clutch set up. All right, but if this 320 00:16:25,440 --> 00:16:29,760 Speaker 1: if the centrifugal clutch material is a little worn or 321 00:16:29,800 --> 00:16:37,120 Speaker 1: glazed or burnt, it'll chatter upon apply. Oh all right, 322 00:16:38,920 --> 00:16:43,960 Speaker 1: makes sense? Yeah, yeah, yeah, get you. The car does 323 00:16:44,000 --> 00:16:49,560 Speaker 1: have quite a few miles on it, u you know, 324 00:16:50,400 --> 00:16:54,240 Speaker 1: not not having said that, ray, okay, how many miles 325 00:16:54,240 --> 00:17:02,000 Speaker 1: were on the car? And you know what it's it 326 00:17:02,080 --> 00:17:04,280 Speaker 1: probably has another one sixty four in it. If you've 327 00:17:04,320 --> 00:17:06,879 Speaker 1: done any kind of maintenance to the engine. Those cars 328 00:17:06,920 --> 00:17:12,359 Speaker 1: go a long time, all right, you know, now, well, 329 00:17:12,400 --> 00:17:15,399 Speaker 1: you know I mean, listen, no guarantees anything can happen. 330 00:17:15,440 --> 00:17:19,439 Speaker 1: But the question becomes, if it needs a trans, you know, 331 00:17:19,520 --> 00:17:22,280 Speaker 1: put a trans on it. It's it's probably worth while. 332 00:17:22,320 --> 00:17:24,400 Speaker 1: I mean, you know, you gotta have somebody do this 333 00:17:24,760 --> 00:17:27,840 Speaker 1: before we just blindly do something. Do what I said. 334 00:17:27,840 --> 00:17:29,879 Speaker 1: As far as tapping the brake pedal, does that solve 335 00:17:29,920 --> 00:17:32,639 Speaker 1: the problem? Take it to a mechanic, Take it to 336 00:17:32,720 --> 00:17:35,760 Speaker 1: somebody you trust, have him do an evaluation on the car. 337 00:17:36,359 --> 00:17:38,840 Speaker 1: If he comes back and he says, hey, it's five 338 00:17:38,920 --> 00:17:40,920 Speaker 1: six thousand dollars to put a trans in the car, 339 00:17:42,280 --> 00:17:45,200 Speaker 1: you know, way that out. Weigh that out against replacing 340 00:17:45,240 --> 00:17:50,000 Speaker 1: the vehicle that you can't find. You can't you can't 341 00:17:50,040 --> 00:17:52,719 Speaker 1: buy one. You can't find one, and if you can, 342 00:17:52,760 --> 00:17:58,600 Speaker 1: you're gonna pay more than manufacturers list price. Anyway, right, 343 00:18:00,040 --> 00:18:02,439 Speaker 1: your care prices are just right through the roof, right 344 00:18:02,480 --> 00:18:05,960 Speaker 1: through the roof, right through the roof. You know, listen, 345 00:18:06,000 --> 00:18:07,720 Speaker 1: you gotta look at you gotta look at what you got. 346 00:18:07,800 --> 00:18:09,520 Speaker 1: Maybe it's worth while to spend some money on you 347 00:18:09,560 --> 00:18:11,679 Speaker 1: gotta get an appraisal. We had a we had a 348 00:18:11,680 --> 00:18:15,760 Speaker 1: customer this week with a nineties seven f two fifty 349 00:18:16,680 --> 00:18:18,760 Speaker 1: that with and it's only got fifty thousand miles on. 350 00:18:18,800 --> 00:18:20,879 Speaker 1: It's low miles, but still it's it's older, it's got 351 00:18:20,920 --> 00:18:24,879 Speaker 1: some rust and stuff. We put sevent it. I'm legitimate. Hey, 352 00:18:24,920 --> 00:18:26,200 Speaker 1: it needs this, it needs this, it needs this. And 353 00:18:26,240 --> 00:18:27,840 Speaker 1: he said, hey, do it. I'm not buying a new truck. 354 00:18:27,840 --> 00:18:30,320 Speaker 1: A new truck seventy five dollars and I can't find one. 355 00:18:30,359 --> 00:18:32,440 Speaker 1: So think about it. If you find the right guy 356 00:18:32,480 --> 00:18:34,440 Speaker 1: to do it, it might be worth while. I'm running 357 00:18:34,440 --> 00:18:36,359 Speaker 1: any in the car doctor, I'll be back right after this. 358 00:19:02,400 --> 00:19:04,800 Speaker 1: Welcome back. We're in the car doctor. Let's let's get 359 00:19:04,800 --> 00:19:07,720 Speaker 1: back to the Phone's Michael and Michigan and ninety four 360 00:19:07,880 --> 00:19:13,600 Speaker 1: four duly and uh no four wheel drive? What's going on? Michael? Uh, 361 00:19:13,880 --> 00:19:17,280 Speaker 1: my forward drive won't work. And whether Dully you need 362 00:19:17,359 --> 00:19:26,159 Speaker 1: for drive? Oh yeah, absolutely? Was this my again? Michael? 363 00:19:26,200 --> 00:19:28,119 Speaker 1: Is is an F two fifty or an F three fifty? 364 00:19:29,880 --> 00:19:33,679 Speaker 1: This is a thirty five ZERI Chevrolet. Okay, all right, 365 00:19:33,760 --> 00:19:35,760 Speaker 1: we got it down wrong. That's okay. So you got 366 00:19:35,800 --> 00:19:40,680 Speaker 1: a K Chevy and you've got no four wheel drive operation? Right? 367 00:19:40,760 --> 00:19:46,199 Speaker 1: All right? Uh, don't light up on the floor dash alright, 368 00:19:46,200 --> 00:19:52,000 Speaker 1: So this has this has electronics shift or mechanical shift. Uh, 369 00:19:52,280 --> 00:19:55,280 Speaker 1: you put it in neutral and you you put the 370 00:19:56,280 --> 00:20:00,240 Speaker 1: one on the floor. You're putting it forward. Drive, yeah, 371 00:20:01,920 --> 00:20:05,400 Speaker 1: and drive and go. Okay, So this is mechanical four 372 00:20:05,440 --> 00:20:10,080 Speaker 1: wheel drive. Right, Yeah, there's no there's there's no there's 373 00:20:10,080 --> 00:20:12,320 Speaker 1: no button on the desk. This is mechanical shift on 374 00:20:12,359 --> 00:20:17,320 Speaker 1: the floor, four wheel drive. Right. You need to trouble 375 00:20:17,400 --> 00:20:20,760 Speaker 1: shoot to see what's going on. All right, So my 376 00:20:20,840 --> 00:20:23,760 Speaker 1: first question would be, because this is mechanical, what they're 377 00:20:23,760 --> 00:20:28,760 Speaker 1: doing is they're engaging the front differential. Two. When you 378 00:20:28,800 --> 00:20:31,560 Speaker 1: put it in four wheel drive, your mechanically shifting it 379 00:20:31,600 --> 00:20:34,440 Speaker 1: at the transfer case. But you're sending a signal through 380 00:20:34,480 --> 00:20:37,879 Speaker 1: a switch to a shifting coder motor on the front differential. 381 00:20:38,560 --> 00:20:40,000 Speaker 1: Have you been under the Have you been under the 382 00:20:40,000 --> 00:20:41,600 Speaker 1: truck and looked around you? Do you remember what it 383 00:20:41,600 --> 00:20:46,720 Speaker 1: looks like underneath there? If I talk to you about it, no, 384 00:20:46,960 --> 00:20:49,280 Speaker 1: you'd never talked to me about it. No. If I 385 00:20:49,960 --> 00:20:52,879 Speaker 1: what what engine? What engines in this? Michael A five seven? 386 00:20:53,080 --> 00:21:00,000 Speaker 1: A big big block diesel? What is it? Four fifty four? Okay? 387 00:21:00,040 --> 00:21:03,040 Speaker 1: This this is a big block. Yeah, okay, this is 388 00:21:03,040 --> 00:21:06,399 Speaker 1: the big block dually all right, so you gotta you 389 00:21:06,520 --> 00:21:09,919 Speaker 1: also got I've been told it might be the electronic 390 00:21:10,720 --> 00:21:14,879 Speaker 1: thing on Pig two. I'm sorry I said that again. 391 00:21:16,600 --> 00:21:21,199 Speaker 1: There's a thing it goes into the dully that's pushed 392 00:21:21,240 --> 00:21:23,679 Speaker 1: to kick it into the forward drive. That might be 393 00:21:23,840 --> 00:21:27,320 Speaker 1: the problem too. Well. No, the duly, when you say duly, 394 00:21:27,359 --> 00:21:32,280 Speaker 1: you're talking about it has four rear tires. Yeah, yeah, No, 395 00:21:32,359 --> 00:21:35,440 Speaker 1: it's got nothing to do with that. The rear axles turning, 396 00:21:35,480 --> 00:21:37,640 Speaker 1: all the rear axles turning all the time. All four 397 00:21:37,680 --> 00:21:39,840 Speaker 1: tires are turning all the time, right, brother, regardless of 398 00:21:39,880 --> 00:21:44,120 Speaker 1: a position you're in up front. Yeah, okay. So when 399 00:21:44,119 --> 00:21:46,840 Speaker 1: you put it in and just don't pull the front, 400 00:21:46,880 --> 00:21:50,000 Speaker 1: don't pull right, The front doesn't the front doesn't engage, 401 00:21:51,880 --> 00:21:54,760 Speaker 1: It doesn't engage, and it doesn't light up on the floor, 402 00:21:55,119 --> 00:21:59,400 Speaker 1: right because there's no four wheel drive engagement. So listen 403 00:21:59,440 --> 00:22:02,719 Speaker 1: to me. Here's how this works, all right. When you 404 00:22:02,760 --> 00:22:05,879 Speaker 1: pull it into four wheel drive on the floor and 405 00:22:05,920 --> 00:22:10,119 Speaker 1: then put it back and drive, you've mechanically engaged the 406 00:22:10,160 --> 00:22:13,600 Speaker 1: transfer case, which is think of it as a two 407 00:22:13,600 --> 00:22:16,800 Speaker 1: speed transmission, all right. Basically, if you want to think 408 00:22:16,800 --> 00:22:19,679 Speaker 1: about a transfer case instead of just sending the power 409 00:22:19,720 --> 00:22:21,920 Speaker 1: to the rear wheels. You've now split it. You're sending 410 00:22:21,920 --> 00:22:24,040 Speaker 1: it to the rear wheels and you're sending it to 411 00:22:24,080 --> 00:22:27,560 Speaker 1: the front drive. Shift through the transfer case makes sense 412 00:22:27,560 --> 00:22:34,760 Speaker 1: so far. That's that's a mechanical lock, all right. So 413 00:22:35,160 --> 00:22:39,639 Speaker 1: you're mechanically engaging the transfer case. But in order for 414 00:22:39,800 --> 00:22:43,520 Speaker 1: the four wheel drive to operate, what GM does is 415 00:22:44,000 --> 00:22:47,879 Speaker 1: there is a shift motor, an electrical shift encoder motor 416 00:22:47,920 --> 00:22:51,280 Speaker 1: they call it, on the front axle. What that encoder 417 00:22:51,320 --> 00:22:53,880 Speaker 1: motor does when you put it in four wheel drive 418 00:22:53,920 --> 00:22:56,439 Speaker 1: at the transfer case, it sends a voltage signal to 419 00:22:56,480 --> 00:23:01,639 Speaker 1: that shifting coder motor to basically electically shift the front 420 00:23:01,680 --> 00:23:09,400 Speaker 1: axle into a locked position. Does that you with me? Yeah? 421 00:23:09,440 --> 00:23:12,680 Speaker 1: I think so? Okay. So so think of it like this. 422 00:23:12,920 --> 00:23:14,560 Speaker 1: If if you got this up in the air on 423 00:23:14,600 --> 00:23:19,520 Speaker 1: a lift, all right, and you know, let the truck 424 00:23:19,600 --> 00:23:22,000 Speaker 1: run it idle, you know, started in four wheel drive 425 00:23:22,000 --> 00:23:24,840 Speaker 1: and let the truck run it idle, what I think 426 00:23:24,880 --> 00:23:29,160 Speaker 1: you're going to see is the rear drive shaft will turn, 427 00:23:30,119 --> 00:23:33,640 Speaker 1: the front drive shaft will turn, but the front wheels 428 00:23:33,800 --> 00:23:41,000 Speaker 1: will not turn. Okay, you got that? Okay? If they 429 00:23:41,080 --> 00:23:43,480 Speaker 1: if the front wheels don't turn, and that front drive 430 00:23:43,520 --> 00:23:47,720 Speaker 1: shaft is turning, all right. What that's telling me is 431 00:23:47,760 --> 00:23:51,480 Speaker 1: you are mechanically locked at the transfer case. The front 432 00:23:51,560 --> 00:23:55,000 Speaker 1: drive shaft is spinning the front ring and pinion, but 433 00:23:55,080 --> 00:23:58,240 Speaker 1: it's not locked at the shift actuator or the shifting 434 00:23:58,280 --> 00:24:04,119 Speaker 1: coder motor on the front differential itself. And in most 435 00:24:04,160 --> 00:24:06,959 Speaker 1: cases you're gonna check for power and ground at that 436 00:24:07,000 --> 00:24:09,600 Speaker 1: shifting coder motor. You're gonna check for signal and ground. 437 00:24:09,960 --> 00:24:15,280 Speaker 1: In most cases, it's a bad shift motor. Does that 438 00:24:15,320 --> 00:24:19,920 Speaker 1: make sense? That is that shift motor on the axle. 439 00:24:20,080 --> 00:24:24,040 Speaker 1: It's right on the axle. Okay. Basically, what you basically 440 00:24:24,119 --> 00:24:26,080 Speaker 1: what you want to do is are you writing? Are 441 00:24:26,080 --> 00:24:29,199 Speaker 1: you writing any of this down? Should I? How are 442 00:24:29,240 --> 00:24:31,440 Speaker 1: you doing this? Michael? Are you gonna remember this if 443 00:24:31,440 --> 00:24:33,040 Speaker 1: you go to if you go to the transfer case, 444 00:24:33,080 --> 00:24:35,160 Speaker 1: there's on the top of the transfer case there should 445 00:24:35,160 --> 00:24:39,359 Speaker 1: be a transfer case switch, all right. If you just 446 00:24:39,440 --> 00:24:41,919 Speaker 1: turn the key on, there's gonna be a brown wire 447 00:24:41,960 --> 00:24:46,440 Speaker 1: at that switch. You should have battery positive, all right. 448 00:24:47,480 --> 00:24:50,200 Speaker 1: When you put the transfer case in four wheel drive, 449 00:24:51,160 --> 00:24:53,080 Speaker 1: there's gonna be a blue wire coming out of that 450 00:24:53,160 --> 00:24:57,679 Speaker 1: switch that will become positive. Why is that? Because when 451 00:24:57,720 --> 00:25:00,560 Speaker 1: you pull it into four wheel drive, you close the switch. 452 00:25:01,080 --> 00:25:04,800 Speaker 1: You ring the doorbell. All right, you know how's the 453 00:25:04,840 --> 00:25:07,640 Speaker 1: doorbell work. You push the button, it closes the circuit. Right, 454 00:25:07,920 --> 00:25:11,400 Speaker 1: you pull it into four wheel drive, you close the circuit. 455 00:25:12,400 --> 00:25:14,800 Speaker 1: And now you've got power on the brown wire which 456 00:25:14,800 --> 00:25:17,400 Speaker 1: is the feed, and the blue wire, which is the output, 457 00:25:17,480 --> 00:25:20,000 Speaker 1: going up to the shifting coder motor on the front axle. 458 00:25:23,600 --> 00:25:29,720 Speaker 1: You're with me the last thing from so it might 459 00:25:29,760 --> 00:25:33,320 Speaker 1: be on the front axle, well right, the problem might 460 00:25:33,320 --> 00:25:35,199 Speaker 1: be at the front axle. Then I want you to 461 00:25:35,200 --> 00:25:38,440 Speaker 1: go to the actuator that's on the axle and you'll 462 00:25:38,440 --> 00:25:40,840 Speaker 1: see this. It's a two wire. It's on the right side, 463 00:25:40,880 --> 00:25:45,280 Speaker 1: passenger side of the axle, bolted up. Okay, And if 464 00:25:45,320 --> 00:25:48,080 Speaker 1: memory serves me correct, it's it's it's that blue wire 465 00:25:48,119 --> 00:25:51,159 Speaker 1: that you checked at the transfer case and a black 466 00:25:51,200 --> 00:25:56,000 Speaker 1: wire which is ground. If you've got if you've got 467 00:25:56,000 --> 00:26:00,360 Speaker 1: the vehicle key on, engine off, keyon engine off, four 468 00:26:00,359 --> 00:26:03,280 Speaker 1: wheel drive, you've got power on the brown power on 469 00:26:03,359 --> 00:26:06,639 Speaker 1: the blue You should have how many vaults at that 470 00:26:06,640 --> 00:26:09,320 Speaker 1: blue wire at the shift at the shifting coder up front? 471 00:26:09,600 --> 00:26:14,520 Speaker 1: Twelve vaults right right, if you put if you put 472 00:26:14,520 --> 00:26:16,800 Speaker 1: a meter across that blue and black wire, and that 473 00:26:16,840 --> 00:26:20,440 Speaker 1: black wire has good ground, what's your meter gonna read 474 00:26:25,040 --> 00:26:29,000 Speaker 1: twelve volts? Right? If you got twelve volts. If you 475 00:26:29,080 --> 00:26:31,240 Speaker 1: got twelve volts at that shifting coder motor with the 476 00:26:31,320 --> 00:26:34,440 Speaker 1: vehicle and four wheel drive and the front axle doesn't lock, 477 00:26:34,520 --> 00:26:36,880 Speaker 1: you've got a dead shifting coder motor. There's not much 478 00:26:36,920 --> 00:26:40,560 Speaker 1: else it can be unless there's a mechanical jam inside 479 00:26:40,600 --> 00:26:42,679 Speaker 1: the front axle, in which case you have to take 480 00:26:42,680 --> 00:26:45,760 Speaker 1: the shifting coder motor apart anyway to see what's stuck. 481 00:26:46,800 --> 00:26:51,640 Speaker 1: Is there any way you can check that? Well? Yeah, yeah, 482 00:26:51,640 --> 00:26:55,640 Speaker 1: I just told you the way all right, basically basically 483 00:26:55,680 --> 00:26:58,840 Speaker 1: what you should experience, right, and again, we're working on 484 00:26:58,880 --> 00:27:01,320 Speaker 1: a lift, we're working on jack stands. We're safe, right. 485 00:27:01,320 --> 00:27:03,840 Speaker 1: I don't anybody under a car when it's dangerous. Okay, 486 00:27:03,840 --> 00:27:07,920 Speaker 1: we're taking When I jacked up block one up, yep, 487 00:27:08,280 --> 00:27:12,280 Speaker 1: I before I get underneath, I pushed on the car, right, 488 00:27:13,119 --> 00:27:15,920 Speaker 1: So because if I can push your car off the 489 00:27:16,880 --> 00:27:21,320 Speaker 1: stands and the jacks, it's not one to come down 490 00:27:21,320 --> 00:27:24,639 Speaker 1: on me. I'm underneath the vehicle, right, so listen to 491 00:27:24,640 --> 00:27:26,320 Speaker 1: me real quick because the clock is gonna grab me. 492 00:27:26,600 --> 00:27:29,800 Speaker 1: You can find a helper if you have them.

And you've got powering ground at that shift case. 495 00:27:35,840 --> 00:27:38,960 Speaker 1: Motor up on the track, up on the differential. You'll 496 00:27:39,000 --> 00:27:41,280 Speaker 1: hear it. Click. If you don't hear anything, click, the 497 00:27:41,280 --> 00:27:44,280 Speaker 1: motors dead. As long as you've got powering ground there, brother, 498 00:27:44,359 --> 00:27:47,399 Speaker 1: it's got to work all right.

Good luck to you, Michael. 506 00:28:03,119 --> 00:28:05,080 Speaker 1: I'm run a ny in the Car Doctor. I'll return 507 00:28:05,160 --> 00:28:21,720 Speaker 1: right after this. Hey, hey, hey, busy hours. We're rolling 508 00:28:21,720 --> 00:28:23,520 Speaker 1: along round Nanny and the Car Doctor at your service. 509 00:28:23,600 --> 00:28:25,960 Speaker 1: Let's get out to Paul in Long Island, OH one 510 00:28:26,320 --> 00:28:28,520 Speaker 1: Chevy S ten pick up. Paul. Welcome to the Car Doctor, sir, 511 00:28:28,560 --> 00:28:31,000 Speaker 1: How can I help? Thank you again? For taking my call. 512 00:28:31,080 --> 00:28:34,040 Speaker 1: You're welcome. Started with p O one seven and p 513 00:28:34,240 --> 00:28:38,040 Speaker 1: O I changed the censor and now I have p 514 00:28:38,240 --> 00:28:42,760 Speaker 1: O one one tending. Okay, so tell me the story 515 00:28:42,800 --> 00:28:45,360 Speaker 1: a little bit. This is this is a um uh 516 00:28:45,400 --> 00:28:48,920 Speaker 1: an O one S ten and it's got it's got 517 00:28:48,920 --> 00:28:52,840 Speaker 1: one engine in it, four cylinder, all right, and driving 518 00:28:52,840 --> 00:28:55,120 Speaker 1: along one day and you got what came up like 519 00:28:55,640 --> 00:28:59,440 Speaker 1: light came on and you and you scanned it. What 520 00:28:59,720 --> 00:29:02,840 Speaker 1: now and you change and you put you changed? You 521 00:29:02,960 --> 00:29:06,920 Speaker 1: changed which sensor? The number two centser and it's only 522 00:29:07,880 --> 00:29:11,080 Speaker 1: single exhaust so it's the sect sensor just behind the 523 00:29:11,160 --> 00:29:18,000 Speaker 1: cat right, so you change the downstream oh two censor? Okay, Um, 524 00:29:18,160 --> 00:29:20,080 Speaker 1: you're sure you've got the right censor in the vehicle 525 00:29:20,120 --> 00:29:24,440 Speaker 1: that you replaced it. It's Amazon made in China. It's 526 00:29:24,440 --> 00:29:28,440 Speaker 1: they never ever worked right, So I mean we could 527 00:29:28,440 --> 00:29:30,080 Speaker 1: sit here in trouble shoot it if you want, Paul, 528 00:29:30,120 --> 00:29:32,360 Speaker 1: but it'll take too much time. Watch just put do this. 529 00:29:32,920 --> 00:29:35,600 Speaker 1: It's not hard to get to right. No, if you 530 00:29:35,600 --> 00:29:37,440 Speaker 1: put the old censor back in, does it give you 531 00:29:37,480 --> 00:29:41,040 Speaker 1: the other code? I chopped the wise and yes, I 532 00:29:41,080 --> 00:29:43,840 Speaker 1: can put it back in. Well, then don't go through that. 533 00:29:43,880 --> 00:29:45,560 Speaker 1: Listen once you get down to your local Lotal parts 534 00:29:45,560 --> 00:29:49,440 Speaker 1: store and buy yourself a real censor, because because it 535 00:29:49,560 --> 00:29:51,680 Speaker 1: just sounds too odd, right, you went from this to 536 00:29:51,760 --> 00:29:56,240 Speaker 1: that there's no exhaust leaks in this vehicle? No, okay? 537 00:29:56,480 --> 00:29:58,600 Speaker 1: And then and then we got to talk about do 538 00:29:58,600 --> 00:30:01,640 Speaker 1: you have a scan tool? If you look at if 539 00:30:01,680 --> 00:30:04,200 Speaker 1: you look at that sensor's voltage. Did you look at 540 00:30:04,240 --> 00:30:07,880 Speaker 1: the old censor? I didn't think to do it before 541 00:30:07,920 --> 00:30:09,800 Speaker 1: I took it out. And the new one is point 542 00:30:09,880 --> 00:30:12,640 Speaker 1: four or five if the engine wasn't fully warmed up, 543 00:30:12,640 --> 00:30:17,800 Speaker 1: but yeah, I think it was maybe at degree engine temper. Well, 544 00:30:17,800 --> 00:30:19,320 Speaker 1: but if you let the engine warm up, if you 545 00:30:19,400 --> 00:30:20,880 Speaker 1: let it come up all the way, does it ever, 546 00:30:22,160 --> 00:30:25,640 Speaker 1: you know, does it ever change from that four fifty millivolts? 547 00:30:26,720 --> 00:30:29,720 Speaker 1: I haven't looked at that. I've driven the car waiting 548 00:30:29,760 --> 00:30:31,280 Speaker 1: for the light to go out, but no, it has 549 00:30:31,320 --> 00:30:34,920 Speaker 1: not nothing. So So let's what am I looking for. 550 00:30:35,200 --> 00:30:39,120 Speaker 1: Let's let's do this all right. You've got two censors, right, yep? 551 00:30:39,400 --> 00:30:42,400 Speaker 1: So does your scan tool let you customize what you 552 00:30:42,400 --> 00:30:46,360 Speaker 1: can see on the screen? No, I just have a 553 00:30:46,400 --> 00:30:50,040 Speaker 1: list that I can scroll through. What here's here's the 554 00:30:50,040 --> 00:30:53,400 Speaker 1: advantage of having something that you can that you can customize. 555 00:30:54,720 --> 00:30:58,440 Speaker 1: How many things can you remember it once? Nothing? Well, 556 00:30:58,920 --> 00:31:01,600 Speaker 1: let's say, let's say to I'll keep you credit for something. 557 00:31:01,840 --> 00:31:03,080 Speaker 1: You know, when you come up to the door knob, 558 00:31:03,120 --> 00:31:04,880 Speaker 1: you have to turn it left or right to get out. Right, 559 00:31:06,000 --> 00:31:09,120 Speaker 1: So a scan tool has to remember at least two 560 00:31:09,320 --> 00:31:14,000 Speaker 1: usually two thousand. All right. The more you make it remember, 561 00:31:14,160 --> 00:31:16,080 Speaker 1: the slower it gets. It's a lot like you and 562 00:31:16,120 --> 00:31:19,280 Speaker 1: me right as we get older. Okay, So there's the 563 00:31:19,320 --> 00:31:22,000 Speaker 1: advantage of having a customizable scan tool. So what I 564 00:31:22,000 --> 00:31:24,520 Speaker 1: would want to look at with this vehicle is engine 565 00:31:24,520 --> 00:31:27,520 Speaker 1: on time. If it lists it both O two sensors 566 00:31:28,080 --> 00:31:31,120 Speaker 1: short and long term, fuel, trim, cool and TAMPA and RPM, 567 00:31:31,240 --> 00:31:33,959 Speaker 1: that's all I care about. I can see all that 568 00:31:34,000 --> 00:31:36,960 Speaker 1: stuff while I'm driving that. Okay, Now, that would be 569 00:31:37,000 --> 00:31:38,520 Speaker 1: nice that that's all I was looking at, because the 570 00:31:38,560 --> 00:31:42,040 Speaker 1: tool would be faster, it would update quicker. But regardless, 571 00:31:42,360 --> 00:31:44,760 Speaker 1: all right, if all you ever see is four ugdred 572 00:31:44,800 --> 00:31:47,000 Speaker 1: and fifty millivolts out of that downstream sensor and the 573 00:31:47,040 --> 00:31:50,320 Speaker 1: engines at operating temperature, and the the the upstream OH 574 00:31:50,400 --> 00:31:55,480 Speaker 1: two is switching high low and doing its thing. Unplugged 575 00:31:55,520 --> 00:31:58,360 Speaker 1: that downstream sensor. Does it still read four ugderd and 576 00:31:58,360 --> 00:32:01,480 Speaker 1: fifty milli vaults? If it's still read four and fifty millivolts, 577 00:32:01,560 --> 00:32:05,880 Speaker 1: that tells me that downstream censors doings. All right, No, 578 00:32:06,040 --> 00:32:08,920 Speaker 1: it moves around. That was just a freeze moment that 579 00:32:08,960 --> 00:32:11,480 Speaker 1: I took that reading it is moving around, but I 580 00:32:11,480 --> 00:32:13,640 Speaker 1: didn't make a note of what range. That's all right, 581 00:32:14,000 --> 00:32:16,280 Speaker 1: So you gotta go through and look and see. All right, 582 00:32:16,400 --> 00:32:18,400 Speaker 1: is it moving enough? Is it doing what it's supposed 583 00:32:18,400 --> 00:32:20,560 Speaker 1: to do? What brand is it supposedly that you brought 584 00:32:20,600 --> 00:32:24,080 Speaker 1: on Amazon from China? It's just as oxygen censor is 585 00:32:24,120 --> 00:32:26,000 Speaker 1: from China. And I don't even know if there's a 586 00:32:26,040 --> 00:32:30,880 Speaker 1: brand on it, right, So how much was it tucks? 587 00:32:31,000 --> 00:32:34,440 Speaker 1: You get what you pay for, brother, that I do 588 00:32:34,800 --> 00:32:37,080 Speaker 1: know better. Uh, you don't get out to your local 589 00:32:37,640 --> 00:32:39,440 Speaker 1: Ralliota parts if you have one. If not, get out 590 00:32:39,480 --> 00:32:42,160 Speaker 1: to Rallyoto dot com. Yeah, get out to Rallyoto dot 591 00:32:42,240 --> 00:32:44,080 Speaker 1: com or are yourself a good oh two centsor a 592 00:32:44,120 --> 00:32:47,000 Speaker 1: Delco and uh it'll be there Monday and they'll be 593 00:32:47,040 --> 00:32:48,840 Speaker 1: able to solve it up for you. All right, kiddo, 594 00:32:49,160 --> 00:32:52,080 Speaker 1: do that call me back if you need more. You're welcome, Paul. Yeah, 595 00:32:52,080 --> 00:32:54,400 Speaker 1: you gotta watch that. You gotta watch that Amazon stuff. 596 00:32:54,440 --> 00:32:56,880 Speaker 1: I mean, it's just you know, from our from our 597 00:32:56,920 --> 00:32:59,280 Speaker 1: next stage China. I'm running nating the car doctor. I'll 598 00:32:59,320 --> 00:33:14,880 Speaker 1: be back right after this. Don't go away. What a back, 599 00:33:15,400 --> 00:33:17,560 Speaker 1: Ronald aading the car Doctor. Another quick hour of voter 600 00:33:17,640 --> 00:33:21,480 Speaker 1: repairs gone by. Um I want to talk a little 601 00:33:21,480 --> 00:33:23,640 Speaker 1: bit about Paul in Long Island. So, Paul, if you're 602 00:33:23,640 --> 00:33:25,360 Speaker 1: still listening, brother, I'm not picking on you. I'm just 603 00:33:25,400 --> 00:33:27,520 Speaker 1: trying to. I'm gonna make an example out of you 604 00:33:27,560 --> 00:33:29,320 Speaker 1: a little bit. But for everybody's benefit, I want us 605 00:33:29,320 --> 00:33:35,320 Speaker 1: to understand what you did there. It's important when you're diagnosing, Hey, 606 00:33:35,400 --> 00:33:37,800 Speaker 1: you gotta write things down. You gotta write things down, 607 00:33:37,880 --> 00:33:40,400 Speaker 1: and you gotta understand why you're changing what you're changing. 608 00:33:40,440 --> 00:33:42,760 Speaker 1: It's just adds bad. Why is it bad? What doesn't 609 00:33:42,760 --> 00:33:46,960 Speaker 1: it do? And no one s ten is like trying 610 00:33:47,000 --> 00:33:51,320 Speaker 1: to fix a two wing or a biplane airplane compared 611 00:33:51,400 --> 00:33:54,320 Speaker 1: to something that's gonna come along twenty years later at 612 00:33:54,400 --> 00:33:58,200 Speaker 1: twenty or an eighteen or twenty two O two. Censor 613 00:33:58,280 --> 00:34:01,120 Speaker 1: technology has grown in leaps and bounds in this the 614 00:34:01,200 --> 00:34:03,640 Speaker 1: last four or five years alone, and it's it goes 615 00:34:03,760 --> 00:34:06,200 Speaker 1: up like the rest of the cars technology every year, 616 00:34:07,640 --> 00:34:10,319 Speaker 1: you know, the aftermarket parts. You gotta be careful, right, 617 00:34:10,440 --> 00:34:12,040 Speaker 1: you know, it's not just a matter of new, it's 618 00:34:12,040 --> 00:34:15,200 Speaker 1: a matter of new. Where did it come from? All? Right? 619 00:34:15,480 --> 00:34:18,560 Speaker 1: That twenty dollar oxygen censor. I don't know that it's 620 00:34:18,640 --> 00:34:21,680 Speaker 1: necessarily that part, but I'd be concerned does it fit? 621 00:34:21,760 --> 00:34:24,440 Speaker 1: Did it did it connect correctly? You know? Do we 622 00:34:24,440 --> 00:34:27,399 Speaker 1: want to go through the pain of testing it and 623 00:34:27,560 --> 00:34:30,160 Speaker 1: verifying does that work? We we could come up with 624 00:34:30,200 --> 00:34:32,560 Speaker 1: some tests for a NO. Two censor to see if 625 00:34:32,560 --> 00:34:36,279 Speaker 1: it works. It's it's easy enough, but you know, first 626 00:34:36,320 --> 00:34:39,480 Speaker 1: step diagnosed properly, second step by a quality part. I 627 00:34:39,520 --> 00:34:42,040 Speaker 1: can't stress that enough. There's too many easy places to 628 00:34:42,080 --> 00:34:45,120 Speaker 1: get it. And I bet you that oxygen censor from 629 00:34:45,120 --> 00:34:48,120 Speaker 1: Orellyota Parts is well under a hundred dollars and it's 630 00:34:48,120 --> 00:34:50,200 Speaker 1: probably half that. I bet you if that's a standard 631 00:34:50,200 --> 00:34:53,080 Speaker 1: O two for two thousand one, I bet you that 632 00:34:53,120 --> 00:34:56,080 Speaker 1: thing is fifty sixty bucks. And to get a quality 633 00:34:56,120 --> 00:34:59,279 Speaker 1: piece versus the piece from China that now you gotta 634 00:34:59,280 --> 00:35:02,200 Speaker 1: crawl back under the truck and go through the whole Michiguas. 635 00:35:02,280 --> 00:35:05,080 Speaker 1: As my mom would say, again, it's not worth it. 636 00:35:05,520 --> 00:35:10,680 Speaker 1: Remember you're diagnosing. You're not checking what's bad. You're looking 637 00:35:10,760 --> 00:35:13,680 Speaker 1: for what's good. Tell me what's good. I'll tell you 638 00:35:13,719 --> 00:35:16,880 Speaker 1: what's bad. And that's how you properly diagnose something, because 639 00:35:16,960 --> 00:35:20,120 Speaker 1: that way you understand the circuit and the components, and 640 00:35:20,200 --> 00:35:23,080 Speaker 1: that way you diagnose properly always a good step to 641 00:35:23,120 --> 00:35:25,200 Speaker 1: go through. I'm not anating in the car doctor saying 642 00:35:25,200 --> 00:35:26,960 Speaker 1: thanks for being with me this hour is always I 643 00:35:27,000 --> 00:35:29,960 Speaker 1: appreciate having you there until the next time. Good mechanics 644 00:35:29,960 --> 00:35:32,279 Speaker 1: aren't expensive, they're priceless. See you
