Hey all, after fishing the wiring harness out of the door I have found the issue. Underneath the the rubber boot in the door jam, right where the fitting goes into the door, my green/yellow wire is cu

Update on mine. I pulled the entire wiring harness out of the door and did a continuity test. The green/yellow wire seemed to be an issue. Circuit 6134 Which is the linear interconnect network (commun

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..

no problem, hope this helps! 

 

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?

      Video processing module location

      By twgraham · Posted

      Can someone tell me where the video processing module is in a 2023 Silverado? I'm getting conflicting results that it's in the front passenger area or the rear passenger area behind the seat.

      Missing thrust bearing? And oil selection

      By Chuck FB · Posted

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    There are a few youtubers out there or one anyway that I have watched a bit of who has gone through the pains of accessing various countries manuals for a certain engine platform and while in the US/Canada it may say use 0W-20 or what have you for some Toyota product, in some other countries it sings a very different tune for the very same engine with the typical traditional oil viscosity/ambient temperature charts to help choose which oil viscosity is correct for the conditions the vehicle will be used in and in some cases its taken an engine in a US manual that states only use 0W-20 as per warranty coverage and yet that same engine in certain other countries may have up to a 15W-40 etc oil option that meets the spec. Another words the guy who is driving through Death Valley or Phoenix and south weather at 120f is often being fed a line of bs by the US system that has forced vehicle companies to restrict the warranty to a specific low viscosity oil for anterior reasons as well as the long drain interval suggestions.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.
