Well, after taking out the back seat, the scuff plate on the driver's side, etc...I did manage to get one of my back speakers working again and cleaned up some of the wiring under the dash. Basically hiding some things up under the dash better and so forth until I get to that part of rewire on the whole car.

However, I replaced the dimmer switch and I still have one headlight that only works on high beam, when you switch to low beam it goes off.

Is it a likely guess this could be the head lamp bulb itself?

The only other thing I can dream up is a bad wire causing a problem but I plan to replace the head light harness next week. The harness and new park light housings just for good measure on ordered and should be here Tuesday or Wednesday of next week.

The dimmer needed to be replaced since the old one was really nasty and I got a good look at my floor pans during the process which was a good thing but only having high beams sure is annoying. I don't drive much at night anyway but nice to have the option should I get an urge to go hang out with the local car club some Saturday evening or something along those lines.

Any ideas? Maybe try changing the headlight?

 

Yeah, it sounds like the light. You can check to see if if has power by using the good side as a reference to confirm it.
