I HAVE A 90 4DR AND IT WAS FINE...BUT I GOT AN ELECTRICAL PROB I..AND I CHECKED ALL THE FUSES AND MAIN RELAY..AND MY ECU SAYS EVERYTHINGS FINE..BUT..FOR EX: IF I OPEN MY RIGHT SIDE PASSENGER DOOR...THE STEREO GOES OFF...I NEED SOME IDEAS..

THANX

 

The ecu and main relay doesn't have anything to do with the stereo. Sounds like you have a short to ground through one of the speaker wires. If it does it every time, check it with a multimeter to confirm that's what it is. The wiring runs through the rubber boot between the body and the door.

 

Who ya gonna call.....
