Hey - I am having difficulty with this issue and was wondering if you had any input. I was driving last night with with my low beams and fog lights on. After about 45 minutes, the fogs stopped working along with the right headlight - just the low beam, the high beam works fine. Anyway, I was off to the part store this AM to purchase new Sylvania sealed beam headlights. I replace all the bulbs in each headlight since I had taken them apart and the right headlight is still not working but the high beam is. I also have noticed the left turn signal blinks much more rapidly than the right turn signal. I an assuming it is some sort of wiring issue in this 26 y/o car but I can't understand why the high beam on the right side would work. Any ideas? Please advise.

If I were you, I'd start by tearing apart the 4 pin connectors for the blinker + headlight (assuming it's like the W123)

Look for shorted out connections.
Look for naked wires.. I had a weird blinker/reverse/etc problem and turned out to be a few naked wires in the trunk touching eacc other.. I guess these naked wires get too excited.. ;)

Work your way back from the connector (trace the wires)

good luck,

Have u checked the fuses by any chance?

Holsten - You were correct! Right on the inside of the fuse box reads the part about the right low beam and the fog lights are on the same fuse. Boy, do I feel like Einstein! I'm glad my parents spent so much money on my education so I could blow it on not investigating the obvious! Thanks for your advice.
