The scenario changes every other time, but right now, here is my situation (68 Bird):

My regular beam headlights will not come on at all. The brights do work though (all 4 are working when I switch the brights on).

Sometimes I get dash lights, sometimes I don't. My turn signals work most of the time. My gas gauge is not working.

I assume it is a ground somewhere, but I have not been able to locate the right one. I replaced all the dash cluster light bulbs, and have also just replaced the light switch. Could it be the dimmer switch shorting everything out? I bought one, but haven't hooked it up yet. Or is it just a ground somewhere?

By the way, all my tailights are working (blinkers and everything). This is getting frustrating!!!! Please help!
