Have a new power window motor on its way. Hopefully get it replaced on Saturday, will update then.

Yes thank you let us all know. I am sure there are more out there that will have the same issue.

 

How was it diagnosed to be the problem? and what was the part number for the motor replacing? thank you

Power window motor did not solve anything. Not sure what next. BCM?

How was it originally diagnosed with in need of a motor?  I think it might be the wires that connects to the truck!?!? No clue at this point. I have exact problem. Anyone?!? Left door part #23171551 harness?!?!?

I am having the same issue with my 2017 GMC.  I dropped the truck off and they replaced the window module.  Its back in the shop today and now they are ordering a new wire harness.    I hate when they need to take the door panels off.  Hopefully they don't need to take a lot of things apart.

That sucks.. Please update when they fix the problem. It would be great to know what the problem was in your truck. Mine sounds like the wiring harness too, but I have not taken it apart yet.

So does this mean the dealership doesn't know what the issue is? They can't diagnose?

Any dealer is only as good as the techs employed there.

Rookies, don't care, etc.

We are diagnosing the same way they are?!? like Diyer2 said, only good as the person they hire..

I have called and they said they have no clue, and have never seen that problem before, but for $180 service fee, they will search for the issue, and $ per hour after that.. They always have never heard of the problem, until you come there with a paper from GM lol..

Hopefully either someone gets it fixed or finds out what the issue is????????

Have you had any luck with the new module?

Hello everyone.  I work as a tech for GM and have for years.  I found this topic after searching it online.  GM has no information regarding this issue but after my findings I filed a field service report with GM to make sure they are aware.  

Last week I had a customer bring his '17 Sierra into the dealership with the exact issues stated earlier, door ajar message and drivers window didn't work.  Both issues were  intermittent.  I checked for any literature that could assist in pinpointing the root cause, and found none.  So I started from scratch.  The window open/close signal and door ajar signal are on the same GMLAN communication circuit.  That circuit runs through the window motor (driver) assembly. Ultimately I found heavy corrosion in the connector to the window motor and the pigtail to the harness.  I replaced the motor and pigtail and fixed the customers issue.  Here are some pictures of my findings.  If you don't find corrosion in the pigtail look very close at the window motor pins.

We appreciate you looking into it. Another person changed the motor that did not work. Could that area be cleaned? or do the parts have to be replaced? Thanks again

With my example the pigtail had to be replaced.  On the other hand; According to GM with almost all their wiring repairs the first step is to clean with contact cleaner and apply dielectric grease to seal it.  If you suspect your application is a result of corrosion but cannot see any, clean it, plug it in and unplug it a few times, apply dielectric grease and see if it makes a difference.

That is great information, thank you from myself and most likely many others with same issue..

What if the motor or harness (corrosion) is not the problem.

I looked and saw no corrosion.

 

Is there a way to test the motor?

All connections/ harness on the the door were checked, and look brand new, put grease anyways aswell.

 

Still had same problem.

 

The window does not roll down, window switch buttons do not work, the horn when locking does not work, and the window lock button does not work?
