Hey there viewers and welcome back to the self made knowledge channel. That's a 2013 chevrolet, it's a silverado! It's got the big five three and the driver's side window switch works fine for all of the windows, except for the passenger side window that one doesn't go up or down. Unless you go to the passenger side and then it works over there. But everything else works.

Good, so let's have a look. Yes, so we're all on the same page. Here we'll kick the key on and you can see the driver's window functions, rear functions, right, rear functions, they all go up and down everything works from the master switch except this little guy. The passenger one nothing happens, but if we go over there it works just fine.

So typically, i would just grab a little wiring diagram here, but i see there's a couple different ones. It says power window circuit with bucket seats and power mirrors, and then it shows you know the switch over here and it show which i was surprised as i can't believe this doesn't work on a low speed data network. This is old style. Like you know, mechanical switches and then i scroll down, keep scrolling and then we get to the diagram power window circuit without bucket seats and power mirrors, and this one you can see, there's no wires on the switch.

We've got a power ground and low speed serial data, which i would expect this to work on. So long story short fast way to find out is just pull that switch out and see how many wires we have going to it and that's going to determine how we're going to test it. I think this grab handle here has to come off. If i remember correctly, you don't tear many of these chevy doors apart, as you did like the old ones, where you're always doing window regulators, i'm pretty certain that this thing comes off yep.

It does so a couple retainers one there there there and there and then we need the classic 10 mil, and then i think this yeah. I think this just pops out once you get the pull handle off. I just can't imagine this having like old mechanical switches. It may be, i guess you know, the other thing that would be faster is just to plug a scan tool into it to see to see what we see.

I don't know where, if it's just a a lin data bus where it just talks to itself, but this really didn't take that long - i don't think to get into this. I could be wrong here, though, pretty sure these little guys just pop up. Yes, sir, look at that. Okay, let's see how many wires we have on the switch.

Oh, who does what here? That's the lock! That's the unlocker thing: let's get this i'm going to unplug the unlocker and the mirrors just to keep the wires out of our way and then we'll do whatever kind of testing we got. Ta do to determine what's wrong. There's that one and i'll move you guys to a better spot to see come on baby. There we go okay.

Now we can see how many wires we have we got quite a few looks like we got four. Eight. 9. 10.

11. 12. 13. 14..

Let's go see: here's what the back of our switch looks like it's a eight pin there and then a couple up on top, so we got two eight pin connectors minus two wires, so 14 wires. This is, though, just said dinner is ready, or lunch is ready. Rather so it is this diagram here, the one with uh bucket seats, because that's what this truck has. So it is correct.

So after i eat lunch, we will come up with a plan of attack, see what we need and what we don't need and who works and what doesn't and see how these signals work and then we'll take it from there. Folks they're dropping stuff right. It's the lunch is over uh. Let's see here, i grabbed this a little tesla, i think we're gon na need it.

We could probably look up the theory in operation how this works. I don't know because it just says, like the outputs uh past, your up signal past your down signal right, rear up, right, rear down, left your up left right down all these. They just caught signals. I don't know if these have logic in them.

I don't. I don't think they probably do or they do to a certain degree, but anyhow, let's just go through and see what we see. So we have a power in the ground which we you know know is good, because everything on everything works up one side. So that's really all we're concerned with is just the one side, but just to show you uh, so we do have power and ground, and then this brown and blue.

This should be the output to the driver side motor which this should light up a test light in both directions, because it's just going to reverse the polarity on it to make it go up and down. Okay. So, let's see, let's check it on a known good. One like let's uh, for example: let's do the right, rear window right, rear output, uh, let's see so right, rear up signal is light green.

Let's see, let's go grab that suspected spanish, as i can see it from here. Let's see so we're not worried about that light, green! So here's a light, green wire, sorry about the cell phone folks. I just want to try to back probe beside that and then we're going to go to ground 250 milliamp light here right, rear. Okay, so it does put out enough current to light a test light.

So that's which way am i going here so that's up and then that's down so okay, so we do know. I guess we can find the down circuit for that one and it should do the same thing right, rear down it's purple, so we should be able to go to the purple wire and that should light up when we go down with that window, and it does So that's down green wire up, so that's what we expect to see for the passenger side. So, let's see, if we're receiving a signal here so passenger up is light. Blue passenger down is tan.

So must be these wires right here. So there's light blue passenger side. Oops bumped into there, so that is passenger yeah no signal out of that one. Let's go to down no signal out of that one.

So that's easy! The switch is bad, which i suspected this when the guy called, because i thought it worked on a lin bus and i figured well if everything else works, it's got to be a bad switch, so i ordered one from chevy. It should be out there on our shelf, so let's go. Let's go get that there. It is folks genuine chevrolet.

I suppose we could have just got it out and plugged it in. But then what do we know? It's a good guess on our part, anyways right plug it in hey. Look that one works now this one works, so you guys are wobbling all over the place. Yes, sir, so they all work.

So that's that that was a stupid video anyhow, at least we all know now uh, i'm i'm a little surprised i'll, be honest with you that they don't run this off a some sort of network. I mean i would think it'd be a whole lot easier to run one wire to each window switch as opposed to you know, multiple wires, but i guess it's not a whole lot of extra. I don't know what do i know, so you just have to very carefully get this thing out without breaking any stinking tabs amazing how much of a car you can take apart with a pry driver. So there's that you could probably pop this apart.

Do a full russian, no parts required fix, but i think it was pretty cheap and then we go like this. I don't have to worry about coming back to haunt me, at least for something i did there's that we'll plug his mirrors back in plug in the lockout switch. Oh, i had a good one in today. Earlier too, i probably should have shared with you guys, but i didn't.

There was a fatal error in service data. I always tell you guys never to trust service data or, if you, if you're in service, theater and something looks abnormal, it probably is so. I was working on this subaru, an o5 outback rear, windshield wiper. I just wanted to get the diagram, so i could see if i had a bad motor or what the deal was but uh.

If you followed the flow chart and service data yeah, i caught the little guy on fire, it was fantastic. I should. I should just do a separate video on that, just showing, like i don't know it's hard to explain, but they gave a pin out of which motor to or which connector to jump, power and ground to and uh. I was looking at a diagram while i was also looking at pin out i'm like man.

If you do this, she's gon na go up and smoke and then so i looked up on oem service data and sure as heck they had their diagram flip-flop. So anyways short story: nonsense. Yeah everything works all right. Let's quit flicking buttons because pretty soon we'll be putting regulators in it and that's that folks and one thing i'm not gon na regulate is how much time you spend in that comment.

Section leave in your questions. Your comments, your concerns, find us on the institute, the facebook. You know what to do and just remember viewers. If i can do it, you can do it thanks for watching bonus, footage time.

Folks come on. I know somebody's gon na ask tell me about the subaru. This kind of stuff is kind of boring, so it's hard to make a video on anyhow uh. You can see o5 outback.

I was working on the rear, uh wiper motor wasn't functioning and i wanted to go and see you know who's supposed to have power who's supposed to have ground and then a quick bypass test does the motor work or is it? You know wire issue? So here it is pretty simple circuit. We have power here, we have ground here and then we have our our park. Uh position signals getting sent back to the i think. It's the intermittent wiper module or whatever um, but it's clear to make this motor run.

We supply you know we can supply power to pin two and a ground to pin three okay. However, when you look on mitchell on demand, it tells you connect the battery to the wiper connector and confirm that the wiper motor operates. Now this is for a o5. They want you to connect the battery positive, to pin four and the negative pin three.

Of course, you know no fuse, which you know whatever you know it doesn't matter but uh. If we connect battery power to number four and the ground to number three and the park switch is closed. What do you guys think is gon na happen? That's why it happens. Your little jumper wire goes up in smoke.

However, when we look at another source of service data, we connect power to or ground to, pin number three and power to pin number two. So, let's see if we hook it to number three ground and power to number two, what's gon na happen? Well, the wiper motor is going to run so and then, as you scroll down through the rest of their service data, where you check the operation of the park switch which they have you doing here, they have it all pretty close like this. This diagram is correct. Um and this diagram is incorrect.

This should also be pin three and two so like i say if something doesn't look right like i said, the only one i had correct was: was this one as far as checking um the intermittent position or the or the park switch rather, but if something isn't Right, it probably isn't if it doesn't jive with your wire diagram, get a factory diagram. If it still doesn't jive, don't don't do something that looks stupid and if you do make sure you record it. So that's it folks, never trust service data ever sometimes you can, but it's not always right. Just because it comes from the manufacturer, doesn't mean it's correct.

I think any time that there's human involvement and stuff writing manuals or anything like that, then there's bound to be errors and a simple discrepancy in where to you know, test a certain pin or where to you know, apply power, don't apply. Power can make a big difference as to whether or not your jumper wires go up in smoke or your new component that you're testing or something so compare sources. That's why i absolutely hate flowcharts, because flowcharts will often tell you probe, pin you know, pin number two and then put your ground here and then it tells you what the value is. But if you don't know what you're doing, if you don't know, you know, what's pin number four, why am i probing it? You got to ask yourself those questions like.

Why does it want me to probe this, and why is this the value that it expects to see and that's why, as you progress or you know, become a better mechanic, you'll you'll start to just you know: throw flow charts in the garbage you'll be able to Pull out a diagram, look at it and say: okay! Well, let's see what makes sense you know. Pin 21 should have power. This one should have this. This one should have that make the notes on your wiring diagram.

You know what to test. You know what pins they are and you know what it value to expect, so you can go right there and make the tests that you need um. I think skinner danner preaches on that, or at least he used to uh. You know he hates flow charts too, and then you just look at it, but sometimes there is valuable information in flowcharts.

That's why we still look at them as mechanics we'll go in we'll look because sometimes they'll have values hidden within the text. To tell you, you know this, you know thermistor should be you know whatever you know, it'll give you a voltage range or a a resistance range on certain items. So sometimes that's helpful and that's hidden within the flow chart. But anyhow long story short.

Just don't trust. Anyone is the moral of this story, trust no one. You.
