This is a Wagoneer, 4 head light bulbs, two are high beam two low beam, different bulbs, they do not interchange. one each had a hole in the glass, but they tested good. I had lost all head lights and the turn signals. Still had flashers and running lights and brake lights. one brake light bulb was bad on the brake light side of the bulb, and one front running light worked on flasher mode but not turn signal mode.
First thought was the head light switch, they are notorious for going bad. But I checked the head light bulb sockets in the harness for grounds and power, and both the white and black wires at the head light bulb (bulb disconnected) were all a dead short to ground with the head light switch off.
?????????????? Looked every where for blown fuses and damaged wires, no joy. So I got thinking maybe the short is in the head light switch?
BINGO!!!!
New head light switch and I now have head lights. Got to get one of those amazon harness kits on this rig like I did the 85 and 89.
But still no turn signals. Odd that both seemed to die the same day. Also the turn signal power (as well as about 5 other loads) bypass the ignition switch on this rig, and the 30 amp toggle switch and other loads all work fine. So I guess the steering column switch needs cleaning????
I have flashers and the two round flasher-blinker relays both work on the flasher line. So it is not the blinker relay. Anything else it could be????
