Soon after picking up my 1994 318is, I began having issues where on hitting sizable bumps, my driver side widow would do the "tip" down as if I were opening the door, causing irritating wind noise. It used to require a severe bump, and the window would reset itself. Now, however, barely a pea would make this thing drop, and the only way I can get it to go up is to firmly pull the door handle, and the window will "kick" back up...usually. Sometimes it goes up, then back down. There's nothing more maddening than the sound of wind noise coming over my turned-up stereo. I took my door apart, to try and see whether there was anything obviously wrong. I immediately noticed that someone has previously torn the door up, likely trying to get to the same issue. with no interior door panel, I close the door and, surely, the window does NOT raise like it should. When I give a firm tug on the metal crossbar to which the regulator is attached, the window goes up. I figure either 1) the regulator just sucks, 2) the door frame got warped somehow causing poor alignment with the regulator/raising arms, or 3) the door latch sensor keeps telling the door that it is open.
Any logical diagnosis here? I really don't have the time and patience to fight this window any longer, and I'd prefer not to have to resort to taking the car to the shop.
By the way, who's silly idea was it to not have door frames and add just one more thing on this car that can break????
