Just wanted to say "Thanks" to everyone from the lists who responded to my queries regarding my speedometer and power window switch problems. I got plenty of replies. Soon as they're finished at the shop replacing my ring gear and I get my u-joint replaced I'll take my C300 in for the speedometer repair. I received plenty of encouragement to repair the power window master switch myself but with my lack of experience and limited schedule I managed to prod a friend of mine who is into electronics to take a shot at the switch. Thanks again. Jerry Browarski
