First Time Fourm Post, sorry if the question has been answered...

The motor, first off, works fine. When I take the window down, the window goes down fine until it reaches the half way point. At the half way point the windows drops about a half an inch (without the motor's assistance). At that point it continues to go down fine. The problem is when the window goes up. At the half way point (when the regulator bars are all aligned) the window pops out of its track. The only way for it to go up without finessing it back into its track is to press the motor switch repeatedly in very short bursts so it stays in track. The actual window is properly attached to the regulator but the window still pops out of its track... I replaced the window motor a while back and it work for about a month (correctly) before this problem arose. It would be a 2002 Cavalier Coupe. Thanks in advance!
