So I'll just buy a new harness lol makes most sense just didnt want to if it were somwthing else possible wrong

So 2019 sierra at4 5.3 8 speed. Today my drive window gave me some issuses went down would come up. Go up about a inch and stop. So I took the door card off too see if I could see any issuses and when I checked my passenger with with that switch it started jerking down and jerking up but would work fine on its own door controls. So I searched it said prob door harness because my power lock and unlock buttons dont work either so I have the harness out and I couldn't see anything wrong with it. Is it worth changing or is it the window motor causing issuses because after tapping it slightly with a rubber hammer it wouldn't do anything up or down the small amount thay it did go. Idk if this is a common issus or what.

So I had my truck in for some diganoses for my vpm and after picking up my truck the hud isnt projecting and I cannot seem to get it on is there a fuse for it somewhere. Also my power lock on drive and passenger side dont work keyless entry works key fob work truck unlock when put in park but the buttons on both side dont work. So is there a fuse for that if so where do I find it. Any help would be great. 2019 sierra at4 5.3

So I have 2019 sierra at4, I had camera issuses since day one I went back a bunch of times about it they keep saying it was fixed but it was not. So now all cameras have stopped working and I brought it to a diffrent dealership and had it diganose and it seems the video processing moduel kicked the bucket. Since I am out of warrent gm won't cover anything even tho it was a preexisting problem. I also had the leak in the rear and had all the seats and carpet replaced because of mold. And according to gm if you had this leak and had camera issuses they should change the VPM to fix the issuse but it was never done and now they won't fix it because I am out of warrenty anybody else have this issuse.

So all of a sudden my driver and passenger door lock and unlock on the interior do not work. The door handel buttons all work all 4 of them and the doors lock and unlock from key fob all windows work eveything works except for both door interior lock and unlock switches. Anybody know if there's a fuse that runs both of them or a place ti start looking.

Any body know where to get 2 piece leaf spring bushing and shakle bushings in canada ?

installed new transfer case motor tonight and still same thing starting to point towards the tccm i guess

i was talking with a guy to day he said that the transfer case motor is a big problem with them so gonna throw a rock in the dark and hope it works

I was reading about this on Google the other day, and my situation is that there is no engine light on and I have no issues other than the fact that my four-wheel drive (4WD) isn't working. Everything else is functioning perfectly. This problem started after I had a bad ground issue, which led to a no-start condition. I found and replaced the faulty ground, but now I can't engage the 4WD. Initially, the Transmission Control Module (TCCM) wasn't showing up until I pulled out the fuse and reinstalled it. Now, I have a long-term memory issue, and the code is showing up under my TCCM module. I'm not sure if the problem might be related to the Transmission Control Module (TCM).

Thanks I'll give that a go at first thanks

I have a 2019 Sierra AT4 with a 5.3 engine. After experiencing a ground failure and replacing that along with a new battery, I found that I was left without 4WD. I scanned the system, but it didn’t show a TCCM (Transfer Case Control Module), so I thought it might be due to my cheap scanner. I upgraded to a new scanner, but it still didn't show the TCCM. However, when I unplugged the fuse for the TCCM and reinstalled it, I scanned again, and now it shows the TCCM with the code P062F-00. My question is: Is there something I can try to get the 4WD working again, or am I looking at needing a new TCCM or addressing something else entirely? I tried clearing the code, but it keeps coming back. All the other codes cleared except for one related to the battery for the key fob, which persists after I installed new batteries. Additionally, the left-side camera has failed, but getting the 4WD back up and running is my main priority. 2019_GMC_Sierra_1GTP9EED0KZ160844_Report_2025-08-27 0452.pdf

Yes no codes the ones that do come up are usually gone by the time I am able to get a chance to scan them and I know if I bring it to the dealer if there's no codes they ain't doing ****** here

Yes replaced the 2 on that side

I have a 2019 new body at4 sierra 5.3 fully loaded had a bad ground strap the large one from the pasenger side engine to chassie the ground was so bad truck wouldn't start. Installed new ground strap and then a new battery now I have no 4wd buttons are lit up but when pushing them nothing happenes get the scattered service 4wd and service esc and loss of steering assit usually resets itself after I drive for a bit anybody got any ideas

so it was the main ground strap from the engine to the firewall under the fender skirt on the passenger side not the 14 inch small one that goes from the firewall to the chassie but the one futher in that comes directly from the motor to the firewall. when i was looking for geound strap location i couldnt find much on location but a guy on here " auto raiders" pointed me in the correct direction.
