my 78 bronco keeps blowing the courtesy light fuse as soon as it makes contact in the panel, its the 15amp one top left of fuse panel, all the other fuses are fine. truck runs but signals and reverse lights dont work.............need help, thanx
Len, the courtesy lights are tied in with the underhood light, and the cigar lighter. Both of these sockets are prone to short out, but I'd first suspect the cigar lighter. If neither of those is the trouble, then check the door switches that control the courtesy lights. The glove box light and switch are also on the same circuit.
