I just got my sons 86 GT titled, and had it running for the first time at night, and discovered the dash back lighting does not work. All the turn signals and other lights work. It's just the speedometer, tach back lighting that isn't working. I'm getting the car inspected this Thursday, which shouldn't present an issue, because it will be daylight, but I still need to get this fixed. Besides bulbs, what could it be?

My fiance's old car had this problem and it was just a faulty dimmer switch. I just bypassed the switch and the lights worked again. That is a possibility.
EDIT: Unless with these cars all the other lights that are working are also controlled under the dimmer switch...I am not near my car to test this out, but I am sure someone else who is wiser will chime in

Dimmer Switch Issues

My 85 and 86 both had a bad dimmer transistor...
