Rear windows only operate at drivers controls

[Sean James]

The rear switches would not have all quit at the same time. My bet it the driver lockout switch, i've had to replace 2 of them, worked both times. The driver lockout gets wet from window down in rain, spilled drivers drinks etc. you can sometimes just pry it out from the tpo, no need to remove the door panel, and at least unhook plug and test it. Piece of cake!

Hey GMT family, recently starting having this issue where intermittently, both rear windows will only operate with the drivers controls on my Denali.

And to fix this all you all did was replace the window switches?

That’s usually the fix. Take the switch from the passenger front window and test the rear with it to confirm.

just for reference info both my rear window switches went funky about a week apart, had ordered and replaced one and the next day the other went funky so....ya it happens
mine would go down but not back up with the rear switch, worked fine from the front switch.
both work 100% again with new switch

If it were a lockout switch problem, I'm not sure there is any pin on the Driver switch connector to fix it, it may communicate with the BCM. From the BCM there are 2 lockout wires (one for each rear door) that go to rear door switches.

That’s exactly what mine does. Rolls down but doesn’t roll back up unless I use the drivers door. It only happens from time to time but I might start with replacing the switches since they’re only like $10.

Im gonna try replacing the switches. I’ve learned it’s easy to do and you don’t even have to take off the door panels. I found them on Amazon for less than $10.
