The window sash channels have broken on my 2002 Pontiac Grand Am. This is the component that holds the window glass in place. The car barely has passed 50,000 miles and the windows will no longer stay up. The Pontiac dealer will repair the piece for $150 each window.

I have a 2-door model Grand Am and the window support clips on both side windows have broken within a month. The windows will not stay up as a result and the dealer has quoted $400 per window to correct the problem. The entire glass has to be replaced to fix the clip.

Driver and passenger windows rubbing? (scratched) windows really scratched ever since I bought it and noticed alot of other cars like mine have the same scratches from opening and closing the automatic windows I spoke to a dealer rep before and they said it was the tinting they used that was too tight? but when my car was brand new and I started to roll up/down my windows it made the scratches, so I decided to hide the scratches by tinting my windows so you couldnt see it as much, but it really is visible. From me speaking with other Grand Am owners that I see that their windows look exactly like mine most of them don;T have tinting. And they look as bad as mine.
