I have a 87 Bronco II with boooookkkooooo miles It has developed a problem that it has no parking lights (front or rear) no tail lights and no dash lights. I have not checked the filaments in the bulbs in the back but brake/turn filaments work.................any ideas gurus
had a problem with a gmc similar to that. part of the circuit in the switch wasnt getting power. i ended finding out it was a loose connector in the multi plug in the harness side. try poking around inthere with a test light after turning the lights on.
