Thanks for all your replies. The window is working now, but who knows when it will happen again. I'll probably want to disassemble the switches and clean them.
I've got a little experience with this. On my 108, the window switches were melted due to lugging the window motor. In that case, I did dissassemble them and found the problem.
What I had to do there was replace them. On the 108, there are no window relays, just the switches between the battery and the window motor. Is there a window lift relay on the 201? I have the CD-ROM, but could not find alot of info on the wiring of the windows.
