I just bought this 82 300D Turbo yesterday I noticed the hazard switch was bad so I replaced it this afternoon after testing it the blinker relay under the front ashtray went crazy. Now no power windows, no temp guage, no fuel guage, & the signal lights went out. I checked the fuse box on the driver's side fire wall they all seem intact. I didn't realize changing a hazard switch can be hazardous to a car. Help!
