Unplugged the door harness & see a tiny bit of green something at the bottom of the connector.  Could this be a little corrosion from getting wet?  Wonder if a little dielectric grease might be a viable solution to my problem?
 
BTW,  I did notice that the wires for my truck  are wrapped in a black cloth tape.

That is 99.95% the issue. I see it all the time. Make sure the black plastic clip is seated in the groove of the rubber boot.

I would try to clean off as much as you can. As I expected. That is corrosion and likely the culprit of your issues. When water gets in, a short will result in the temporary power loss of the window switch, making it want to relearn.

Hi, 

I have a 2015 GMC Sierra Denali and got it Thursday of last week. This morning I started to have the same problems with the exception of absolutely no power anywhere. Dealer towed it to their mechanic and fixed it for the day. Until about 6 o clock and the truck quit in traffic unexpectedly. I got out and jiggled the negative post and everything came back on. On the way home from work tonight that message came up. I am relaying this thred to the mechanic in hopes of him fixing this issue tomorrow morning. The truck died as I pulled into the mechanics parking lot just 30 minutes ago. Will keep you posted on his results!

My 2019 Chevrolet Silverado will shut off while going down the road when starting back up the dash message says roll down driver window then back up… I’m wondering what was the out come of your issues.

Check your harness connector in the door jamb. Did you notice this happen during a rain event? If water is intruding at the boot, it is likely getting a short as the main power and ground branch is at the bottom of the connector.

Also, this main power wire hits the driver window motor. So if you can check there for signs of corrosion, that might be it.

I’ll be also seen the large power/ground wires slightly severed where they could potentially ground out.

Phil, could you PM me about a problem with my 19 3500 no start issue?

Thanks

Now mine did same thing for a few days and then eventually stopped working! Changed window motor, wire loom in door jam is a bit corroded, noticed passenger puddle light wasn't as bright as driver's, now driver's puddle light works- passengers dont. As soon as I open door all is good till half open than message came on! Now it just says open an close driver's window, door ajar, stabilitrak, trailer brake, power steering,and the list goes on. And yes it was raining and I left door open to pull someone out and I've checked all fuses and battery dont seem to be up there in charge some times....I've got a spare ECM and bcm programmed to my vin and was going to switch them to see if it would cure my issues but haven't yet. I don't get on here very much if youd like to email me at [email protected]

Steve, did cleaning this up fix it for you? We have the same thing going on right now. Sorry to hear about your saga.

Yes it did.  Showed my pics to the service writer at my dealership and they cleaned it up.  Would have done it myself but they also needed to replace the window tint so I had them take care of it.  Been several months now since I've had this error come up... knock on wood...

That’s good to know. I just pulled my plug and it’s not crowded at all so I put some dielectric grease in there. Perhaps it got water in there and hasn’t done it enough to build up corrosion yet. I might just silicone around the rubber seal because it’s not really that good of a seal

Not sure if you fixed the problem, but im Having the same issue. I noticed one day while my driver door was open, the window wouldn’t go up or down. I wiggled the wires in the door jamb and it worked again. Must be a broken wire in the door jamb. If you’ve fixed your problem let me know what the issue was!

My issue hasn't returned and it does appear that it's been fixed... knock on wood...

I have this same problem but when I get to work or get home and park it, it completely dies. I did trim the material back from the ground located near the tweeter on the driver side but it still does it and my dash flickers while driving

I recently hooked up a dash cam setup. I disconnected the negative on the battery and it sat like this overnight. When I hooked it back up and started the truck I got the window message 

Down and up with the window and message went away.

The last time I disconnected the negative on the battery I got the same message. 

So it has to be something with losing power.

Ok, So part of this is exactly the problem. It's just very general which doesn't help you and that's no fault to @rusty503. He is exactly right.

 

I have run into this many of times on these vehicles since i am the electrical specialist at our dealership . Unfortunately I can't see the vehicle to test it so I am not going to say it is not a body control module failure. Because it absolutely could be. Do I think it is? No. But again I can't test it personally so I will not say they are definitely wrong. I will explain to you though why I believe it is wrong and what I think you should look for in case the BCM does not fix it. And please, If the BCM fixes it let us know. I really enjoy these types of problems and am interested.

 

The BCM uses voltage to keep it's memory (this is why it could be a bad BCM) When it falls below a certain voltage the Capacitors in the BCM discharge and this sends it into a relearn mode (telling you to roll the windows up and down, ect..) This is why I don't think the BCM is the problem.


I believe you have a voltage drop problem on one of your battery cables. This is actually an easy test and don't take long. Do a loaded voltage drop test across your battery cables. You need less than 0.1 volt across all of them even though 0.2 volts is acceptable.

 

If your voltage drop is higher on any of those cables or across the battery block (which is where I normally find the problem. Either a lug that's barely loose or a crack in the plate) replace it. The reason it's coming up with this is because during cranking the voltage drop is higher than normal. If you have (let's say) 2 volts of drop during cranking that means on a perfect battery your BCM would be seeing 10.8 volts and discharge the capacitors causing your vehicle to go into relearn mode.

 

Here is the catch. Your vehicle isn't doing it every day (which makes me think it is the battery block again..loose lug or crack) so you will not see the full drop. But anything higher than 0.20 needs to be replaced. This will fix your problem IF the BCM doens't fix it. Because again... I can't test the BCM myself. I just have my doubts about it... But it is possible.

 

If you need me to explain anything else, how to do the test or ect... Just quote me and ask so I get the message on my phone. If not i check here every few days. The Ad's are killing me and I don't really like to come here much anymore.

 

 

 

 

Hey my 2017 just started doing the window up down message and telling me to do it every time I start my truck. Also how do I test the bcm?

Phil, I have been having this issue for a few months. Recently, the driver door open notification has added to the list. I replaced my driver window switch as that was a suggested resolve and "that switch tells the vehicle the door is open or closed." Im going to check the harness in the door this week. My harness is a replacement that was repined to make the upgraded OEM mirrors fold on my truck. If I happen to find the corrosion as described, what is the best suggestion for cleaning it up?

I am having this problem now.  Been to the dealership twice; Goodyear 5 times.  I reset the window by letting it roll down hold the button for 10 seconds; roll up hold for 10 seconds.  It went away for 3 weeks but now it is back.

    • The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.
    • So I purchased the Range unit for my 2026 and I am seeing different locations suggested for the ECM . Can anyone confirm wither under hood, left side or right side or behind the wheelwell?
    • Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that. 
    • "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
