Just went through this myself yesterday. My window worked on a cable pulley system, there are 8 bolts that hold on the window regulator which includes the motor. My motor and regulator where fine. The glass is attached to the regulator by two plastic clips. The front clip is $42 the rear clip is $38. It is easier than you think to fix. I hate working on cars but the dealer wanted $350 to fix it so I took 45 minutes and did it myself. This site has a great step by step diagram. http://www.a1electric.com/grandam.htm !
Happened to our 1999 Grand Am 2Dr. Dealer wanted $529.00 to fix it. I purchased the whole Window Regulator, including the motor, new off Ebay for $65.00 delivered.
Cheaper to buy the complete Regulator with plastic sash clips than pay a dealer $50-$60 for just the plastic clips. That is if you can find someone to just sell you the plastic clips.
The other posting the A1electric site is what I used as my picture guide. Helped a lot.
If it looks the same it will probably work.
At the Pontiac dealership or eBay just type in Pontiac sash

with a window crank removal tool.
There are guides that clip on the glass, one is on the upper rear of the glass,and the is on the lower front. Most of the time the one on the rear breaks causing the window glass to tip forward. You can remove the old clip & install the new while the glass is out of the track.And then reinstall the window by seating it back in the channel.
change the window regulator
1999 Pontiac grand pre how do I bypass driver window so I can get it up.
In a 1991 Pontiac Grand Am : According to my Chilton's Auto Repair Manual : ( 13.6 U.S. gallons )
Order a new window regulator, and you need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.
