So last week I rolled my driver window down and it wouldn't go back up. I can hear a clicking sound inside the panel somewhere, but nothing happens. I figured it was a dead motor, went to work and came back out later and for the hell of it tried the window and it rolled up. Had the car at the shop getting crap fixed on the rear end today and the mechanic who didn't know about the problem (I forgot to mention it) rolled that window down and lo and behold, it won't go back up again now. I tried turning the key off and on tonight, about an hour ago while it's pitch black outside; something that freaked me out a little, however, was a flash of light inside the door panel a couple of times when I tried the switch, telling me it's sparking somewhere. The motor worked great before it crapped out, so I'm thinking short inside the panel? My car's had an issue of late with the voltage dropping and fluctuating in idle, with the lights dimming when my foot's off the gas. Could this be related to that or are they likely separate issues? I know I need a new serpentine belt so I thought maybe that was causing the issue. Thanks for your help!
