05 GMC 1500 Power Window Not Working

It started out as an intermittent problem a few days ago, sometimes the drivers window would operate...but now it's totally dead. The motor was strong, there were no signs of binding or weird sounds so I think the regulator is in tact. I'm guessing it's just the switch itself that died. All other 3 windows work fine, and the door locks and power mirrors work fine. Just the driver window switch that appears dead.

 

Are there any fuses that control the drivers window switch separately? Is there a way to repair the switch or do I have to buy a whole new switch panel? Wondering if anybody has cracked them open to re-solder or repair. Didn't find much out by searching. It's getting too warm outside for no working window! Any help would be great. Thanks!

I checked all the rises and didn't see any problems. I took apart the switch and didn't see any burns or bad parts. I didn't see any links or breaks in the window wiring. What do you think it could be? Should I just order a new switch and see if it works?

See if you have power at the motor. Wouldn't be surprised if the motor took a dump

Yeah I applied direct power to the motor. It goes up and down just fine. Had to be something hidden in the switch or wiring,in guessing. What else could it be?

Then it would likely be the switch, if no power is present after leaving the switch.

So go figure, today it's back to intermittent working. I can hold the switch up or down and the window will go a little, then stop, then move some more then stop. A constant off then on...all while holding the switch the entire time.

 

Makes me think now that the motor is going out. I'll have to do some more direct power tests on the motor. Is there anything that can be checked besides just putting power to the motor?

Well it's been working great for a week. Then this morning it goes down fine, but to get it to go up, it almost needed help. I was holding the switch up, and it was jittering/shaking a bit before it made it to the top. Would that be a motor going out?

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
