The headlight switch is worn, doesn't have a good click-action to it; not sure if it's the problem. Tonight high and low beams were dead, tried turning the switch through the ranges a few times and apparently something took a fuse out; no dash lights or right side lights. Swapped fuse, fixed that problem, but still no high or low beams! What should I be looking for?
