Name that electrical problem... 1984 944

Postby galis on Sun Dec 12, 2010 4:23 pm

This is a 1984 944, anyone care to guess the electrical fault?

Recently I noticed my turn indicator would light up in the dash but not blink when I set it for either direction. The exterior signal light remains off too. At the same time, the "buzzer" that signals when shifting into reverse has stopped and the reverse lights don't come on. Both electric mirrors have stopped functioning. The hazard blinkers do work, the brake lights are working too.

These are the only symptoms I've noticed and they all seem to have happened at once. (I guess that doesn't mean only one part has failed though.) Best I can see, the fuses look okay. Relay? Any way to tell from this much info?

Kodos to anyone who can give me the info to fix it myself, I just finished service post broken timing belt (failed at about 15,000, due to high temps/coolant leaks after failed water pump, or possibly it was an old belt at install, or ???).... otherwise she is perfect as ever

Good place to check for electrical gremlins like that is the electrical portion of the ignition switch. At least that's where I would start after checking fuses, relays, and cleaning all 7 main grounds-especially one under dash and on engine firewall.

Thanks!
Resolved. After market relay bad contacts due to heat/corrosion in the insert tabs.
