I have a 90 Festy. I noticed the other day that the dome light, seat belt warning light, and door buzzer would stay on even when the door was closed. I figured it was a simple issue with the door switch, but that wasn't the case.
When I put the car in reverse, the activation of the reverse lights would stop the lights and buzzer, but as soon as I came out of reverse they would come back on. So I thought it was something haywire in the reverse light circuit - nope.
I basically gutted out the little rice grinder, removing the seats, carpet, and headliner in order to trace the wiring to the problem.
Under the dash, on the drivers side just above the left kick panel are several key electrical connections. They were sopping wet. I unplugged them to find a massive amount of corrosion had built up from the moisture inside of them and was causing a false ground in the door buzzer circuitry. I cleaned them and applied a liberal amount of de-ox inside each connector. I plugged them back together and BINGO- no more electrical gremlins.
So, what was causing the moisture? well, I thought it must be coming in from a hole behind the drivers fender, so off it came - I found nothing. I poured water into the windshield wiper compartment - nothing. I finally poured water around the radio antenna, and drip drip drip. So, I used black RTV silicone under the base gasket of the antenna, and it fixed the problem.
So, I hope this helps some of you avoid the frustration of electrical issues.
