Mein Auto: 325ci
window goes down but not up

I have a 2003 325 ci. Last weekend I rolled the window down and it wouldn't go back up. I checked the fuses and they were fine. Then we pulled the door panel off(what a bear) and removed the motor and operated it seperately. It worked fine. We raised the window manually, reinstalled the motor and tried again. The window went down fine but would,t go back up!!! I forgot to mention that I'm dealing with the passenger side. Also the regulator doesn't seem to be broken. Any ideas on where to start?

Thanks,
Don

Don change out the window switch with a known good one (another window in the cars switch). I've seen bad switches do this more times than I can count.

If the window goes down when commanded down via the switch and still goes down when commanded to go up via the switch then the switch is bad. It is not a motor problem, general module problem or regulator.
