When I hit the switch, it makes a click, but no juice. I don't think the click is the sound of the switch being depressed, because when I depress the passenger window switch, I hear the click at the passenger window rather than at the switch.

So what I think is that the switch is functioning, and it's getting juice, but something in the motor is either burned out or not functioning.

Any ideas what it could be? How can I test it out before spending hte $$$ for a new mechanism?

Thanks.
