I have had to replace two of the motors for my windows (one of them in a rear window which is never even used!). I work with 5 other people that have had at least two-four motors go out on their Pontiac also. This appears to be a recurring problem with Pontiac and has caused me to reconsider buying a new Grand Prix.

3 out of 4 windows do not operate on a 4yr old car because a little plastic retainer clip broke on each window leaving the window un operable. The driver window, the driver side rear window and the passenger rear window.

My car is a 2000 Pontiac Grand Prix gtp. In October 2003 and March 2004 I have had power window failures. The first incident involved the driver's window and the second involved the driver's side rear window. The total cost of the first repair was $457. The second repair is estimated to be at least $400. I have read many similar experiences on the internet with window failures, as many as 11 times on one car. I was even alerted to a law firm considering a class action suit on the matter.
