i used to have to hit the switch a few times for it to work, and now it doesen't work at all. the passenger side switch never really worked, so i had to use the driver side passenger switch, and it would always go up really slow, and now it doesen't work at all, and all it does is make a click sound when i hit down on the switch, and doesen't make any sound when i hit up. i took my door panel off yesterday in my auto class, and i don't really know what to look for too see if it's shorted or has moisture. any tell tale signs?
Thanks.
