I drive an '81 300D.
I was driving home from work one night recently and I quickly noticed that I was riding cyclops. The right low beam was out. I flicked the turn signal stalk back, and both high beams came on.
I took this opportunity to replace both headlight units with new Sylvania H6024XV sealed beams.
When I got the replacement lights hooked up, I discovered that the right low beam would still not come on. Furthermore, I found that when I pulled the rotating switch outward, the fog lights no longer came on.
I'm not an expert on these or any other cars. I gave up after I found a little fuse box under the hood on the driver's side. All of the fuses appeared intact, although I must admit that I'd never before seen fuses that looked like these; I observed that none of the little metal strips were burnt or missing, and that everything was firmly seated.
Now it's vehicle inspection time, and I need to resolve this annoying issue.
I ask you: what's up with this crap? Does it sound like something simple, like a bad headlight switch? Or am I in for wiring hell?
I'd prefer to take the car to a professional rather than do further damage by attempting a complex electrical repair myself. I'd appreciate it if an experienced W123 person could tell me what kind of trouble I've got on my hands.
