Well, it seems like my problem is not unusual. My driver's window, after a few months of sometimes working, sometimes not, has finally stopped going down. I read in these threads where others have had similar problems, and I even used one idea that worked for a while. I pulled the door panel and tapped on the motor with a wrench, and the window started working for a couple of days. Stopped again today. I read that someone took out the motor/regulator and cleaned it to remove carbon deposits, and it's working fine. Can anyone tell me how to remove/replace the unit so I can try that? I see three nuts that hold it in place, but I'd hate to get into something I can't handle. Any help would be appreciated.

My passenger window was having a similar problem, it would go down part way then stop and not move at all. I could hear the motor clicking to work but nothing happened, so I took the door apart and removed the window and motor. The motor is plastic and the rotating shaft had worn a small track in the plastic. To make a long story short, I used a utility knife blade and placed it in the top of the motor housing where the worn spot was and made sure that there was plenty of lubricant on the side with the rotating assembly. Good old fashioned shade tree mechanicing :cool:
