They worked fine in the fall when I parked the car, but they don't work now. I've tested all the fuses, and they are good. I have no power at the fuse box at cavity number 5. Using the factory wiring diagram, I jumped the circuits from the hot wire coming into the headlight switch connector and can get both the dash lights and the tail lights to work. When I jump the dash lights, cavity 5 then has 12 volts. I can run the hot wire to the headlight switch, turn the switch on, and get 12 volts coming out of the switch at the headlight lead, but not the dash or the tail lights. I've tried adjusting the dimmer switch. I bought a new headlight switch, and its doing the same thing. Is it a bad switch, even though its new? Am I missing something somewhere else? Suggestions?
