ok, as for the headlights, check the wires going into the relay block under the dash. Mine had a fire there due to a loose connection. If the relay is clicking over then it is more than likely an intermittent ground( not necessarily a ground wire but a wire grounding out somewhere if that makes sense.) Also, check the resistance across the terminals on the lights themselves.
Main power is RED/LIGHT BLUE. to headlight relay. out of relay is RED/WHITE splits and connects control switch and dimmer switch. Out of relay to fuse block is RED wire. Out of dimmer switch is RED/YELLOW to headlights. RED/GREEN from lights ties them together and goes to high beam indicator light, then WHITE/BLACK to ground(one near the regulator the other to the right side of instrument panel bracket)
From the fuse block: to left headlight is RED/WHITE; to right headlight is RED/BLACK.
There are 2 15AMP fuses in the block one for each headlight.
Hope this helps.
