I read through a bunch of these pages but not all of them. Sounds like mine may be the motor? I was lowering my windows (e46 M3 coupe) and paused them half way. Except only my driver's side paused. My passenger front window went all the way down and now won't move AT ALL. No previous sounds/noises... as well as no crashing sound. Also, there is also only a tiny click sound when I press the button. No grinding or other noises can be heard.
Do you think this is the motor? Please help asap as I'm trying to make an M3 meet by Saturday! Thanks.
