the head lights , brake lights, work. turn lights work in the front and rear but rear sides don't. and when I turn the running lights on nothing works, front or rear. the dash lights worked at first but don't now. all the lights inside work when the door is open. but will not with turning the switch. the flasher switch works all but the 2 rear side lights.
I'm going to change the switch out tomorrow. hope that works. any other ideas?

I know you said you were going to change out the switch...but have you?

You mentioned the rear marker lights didn't work is that correct? If so you may have a grounding issue - its a notorious problem in these cars. Are the two rear grounds attached in the trunk? They connect to either side of the trunk latch from the rear tail light harness. And while you're at it I'd check the grounds in the engine bay for the marker lights. They should connect up to your radiator core. The problem I ran into with mine was that I had the radiator core powder coated so I wasn't getting a good ground from the surrounding sheetmetal so what I had to do was run a dedicated ground from the battery to the radiator core.
After that, I'd make sure the bulbs are good. Next obvious and cheap fix :)
Up next I'd replace the headlight switch.
After that it would be time to start tracing the wiring under your dash and through both the forward and rear light harnesses to see if something got cut, burned, etc.
