Hello -- I have a 91 190e 2.3 and one of the rear windows won't go all the way up. My son pulled down on the window as it was going up and it has not worked right from that point on. The motor seems very strong and the window goes up and down with no problem, it just won't go all the way. The window stops about 2'' from the top of the frame. If anyone has any ideas please let me know. Thanks in advance for any help you may be able to provide. Lance
