Have you tried the manual winder trick? It is documented in the owner's manual, if you have one. You pop off the cover or the tweeter if your car had one, put a 4mm hex key into the opening until you feel it slot in (to the motor), and turn to the left. The car came with a tool for this, if you still have the original tool kit. I had this problem last year, and using the tool, popped the window free and then it worked fine again with the switch... Until it stopped again. I haven't gone back to it, but I guess I need a new motor or regulator. It wasn't the switch in my case.

I can take a photo of the manual page if you need it.
