Power Sliding Rear Window

[07cliffordreddog]

This afternoon I had the power sliding rear window open on my GMT900 crew cab sierra and when I went to close it, it only went half way closed. So I pushed the button and opened it again and tried to close the second time- same thing. It just would not shut, then it wouldn't open. No movement at all. I was able to slide it closed by hand, which took some muscle... but still not the whole way. It's about a half inch from being totally closed and I can't force it any farther. I sealed the gap with some packaging tape for the time being.

 

Truck is under warranty so I'll be calling the GMC dealer on Monday. Just curious if anyone else had this problem. Being that my GMC dealer is about 45 miles away, I use the chevy dealer in my town for all my general repairs but I'm pretty sure they can't do warranty work on GMC's... am I correct?

Any GM dealer can do warranty work on any GM vehicle, regardless of brand. Some dealers don't like working on brands other than what their store sells, but GM doesn't prevent them from it.

What was the weather like at the time? When it gets cold here, my back window won't open.

Happened to my 07 NBS a couple months ago. In my case the small anchor at the end of the cable system that opens and closes the window broke off. Look in the botton channel and you might see the cable in there.

 

Covered via warranty without any issues and they even stepped up with a rental Silverado for the day.

Why would you open your back window in the Canadian winter?

This happened to my 07 NBS when I first got it. Same thing that K9Blitz said. There is a TSB on this.

I did see that cable in the bottom channel... thats what is preventing me from getting the window the whole way closed. it is stretched very tight, its like it got caught up on something and doesnt have enough length to close.

 

Thats very good info to know about any dealer being able to do the warranty work. I called my chevy dealer yesterday right when it happened to make an appointment and the service writer said no way could he do work on a GMC under warranty. Looks like I'll have to call out there monday morning and try to talk to someone else and see what they say.

Early 2007's, this was a big complaint... many had that problem. Just take it to the dealership to have it fixed.

I had the exact same problem with my truck.

Well that answers the question on the power sliding window. NO

[07cliffordreddog]

I don't even use that window often. honestly, that was about the 3rd time it was open since I bought the truck. Honestly, that's what makes me mad about the whole thing... it wasn't somethin that whould have worn out and needed repair! but it sure was an easy way to haul the 3 pieces of 8 foot long pvc conduit without tying down and hanging out the back of the bed

Because I thought air was coming in from back there so I tried to open it and close it.
