My passenger side window did the samething. I had a friend of mine that replaces windows and window motors and he cleaned it out. He said there was like sand in it. It worked for about 2 weeks and then it stopped again. It's been about 5 months since I have had time to replace it. But summer is coming and there is no way I am going through summer without a passenger window. Does anyone know if you have to replace the regulator when replacing the motor?? My buddy said all I needed was the motor but I am not too sure.
