Update on the wiring issue. You gave the exact description of my problem, and after a rain delay, found the same exact wire broken. Everybody should follow your suggestion to troubleshoot, not be a parts replacer. Now to what I hope is not the more difficult part of finding the part and getting things back together. Thanks again for your timely advice. Onward and upward.
Yep made the mistake of buying the switch and having no luck, pulled the whole thing apart as just my mirror switch wasn’t working for me, turned out little green wire with white stripes had snapped in the door jam, fixed it and everything works well now
You got any recommendations on a 2014 silverado front windows not working but rear are, also driver door always reads ajar. Codes U1534-00, U1538-00, and U153A-00. Wires ohm good haven't found any breaks or corrosion in driver door.
Mines just stopped working but the power mirror , window and lock only on the passenger I've noticed when they shut the passenger front door the music stops for a quick second but im pretty sure I'm having this problem the speaker still works though
It's sad because I have a 2006 GMC yukon and the door wiring harness has not given me any problems. I have a 2018 Sierra, and so far everything is okay, but I've seen this issue many times on these trucks. Has GM really skimped that much on the quality of wires?
Quick question. My driver mirror on my 2014 Chevy Silverado got knocked off and I had to rebuild the motor but when I put it back together the motor continually runs when the vehicle is locked I'm wondering if you know why that would happen?
I have a 2016 Chevy Silverado 2500HD and none of the window controls work on the driver side but the switch one the other doors work for their windows. The only button that works for that section is the child safety lock. Could it be a wire and if so where can I find the part to replace it?
Question, how do you find a good pdf of the wiring schematics? I bough a haynes manual but with my older eyes I can't read the diagrams. I always end up scanning the pages and blowing them up so i can read them
We use a few systems. Alldata Identifix Mitchell on demand Or you can use a site I work on called justanswer.com and a tech can supply you with the diagram. I think you can get a days pass for alldata from autozone Alldata diy its called or something. Also check nastf.com it shows all the manufacturers websites
Question with my tow mirrors. They are power folding but they don’t fold. Everything else works as for power in the mirrors would like to fix it as it is annoying to get out of the truck an manually fold them in. When I hit the fold button I can her this clicking sound over in the passenger side. Wondering what is going on with it. Blown fuse or bad wires. I just picked the truck up a few months ago 2015 gmc Sierra
Clicking is signs that the motor is broken or teeth in the gears. So power would be present. But the master switch controls the power and ground. Both sides have same wire colors. Grey with a white stripe and white with a green stripe. Theres like 3 connections between the master switch and the mirrors 😭😭😭. Gm and their darn connections. Can either ohm from switch to mirrors or also watch my simplified diagnosis video on how to check wiring.
I can almost guarantee you they broke when you went through a car wash, and they either pushed the mirrors back, not knowing they were automatic, which will break them exactly what happened to mine
My 09 Chevrolet Silverado driver window rolls down but mirrors switch, lock switch, passenger window and rear door windows wont. Rear windows wont go up or down either with their individual switch but the front passenger window individual switch will roll up and down.
Hi I have a 2006 Chevy Silverado. And my marker and tail lights stay on for around 10 minutes. The dome lights go out in about 1 to 2 minutes. Why do the marker lights stay on so lot. I been trying to figure this out and no one can answer my problem. I replaced the head light switch, the relay. It’s not the radio,and day time Amber sensor. Do you have any idea? I’m scratching my head.
which relay? there is a parking light relay, that may be sticking closed . The parking lamp relay is activated by the BCM. So either the relay is sticking closed or the BCM is keeping the relay energized. the circuit seems very simple. The headlight switch tells the bcm its position, then the BCM activates the relay .
So I hAve 2021 Chevy Silverado 4 door . I got a aftermarket amp installed and now the passenger window won’t go down and the amp step won’t go down if the front door opens. The back passenger door when open it will let the amp step go down and up. The power mirror works on the passenger side. Can anyone help me

We were doing this 20 years ago, customers would get mad when you split the boot at the door lol. Great video!! 👍
Exactly what I suspect is happening and was hoping it wasn’t… guess I will be digging deeper, thanks for the video!
Exact same symptoms with my 2016 Denali. Will check and hopefully repair. Will repost one way or another. Thanks.
Thank you for this video just got mine fixed and working. Didn’t find any other cracked just the red and violet one.
Thank you so much, my truck was giving the same issue and I found the same broke wire and was able to repair till I can get a harness thanks again!!!!
This was exactly the thing I was looking for when I logged into youtube this morning. Thanks bud, subscribed.
Glad I could help, sorry I dont have many more chevy videos if thats what ya need but in time ill be teaching more and more
Great info. Same thing happening now to my 2500 Chevy 2019
Thanks to this video, Im going to blindly replace the harness with no further trouble shooting 😂
You just became a TH-cam Certified Technician! 😂😂
Love it!
How about a video on replacing the harness? Have you seen one out there?
Thank you!
I just watched your vid on the scan tool and you used the wings an example, great content glad I found your channel thanks
Thanks it worked for my truck great video👍🏻
Nice job. You look like lou from from the muscle car show on motor trend

would that stop remote start from working as well? also what was the part number for this harness same exact issue going on
Your best suggestion to get a wiring diagram for the 2016 Denali. Also, did you remove or modify the wire harness between the body and the door?
I use identifix and alldata wiring. I replaced the harness for the door , got parts from the dealer.
@@MasterTechLou Thanks. I'll check a little further before l leap into the abyss, and thanks again for the speedy reply. Have a good evening.

how do you disconnect the wire harness?

curious, I'd bet this happens more often on trucks in cold climates.
Hey Lou, any thoughts on the x tool D8 ?
I havent sampled it yet
But im very impressed with the A30M so I can imagine its a little better

My 2017 passenger side mirror dont work.
My 2003 Venture windows and mirrors won't work unless the driver's side door and a door on the passenger side are open.
most likely a broken wire in one or both door jambs just like this car.
