My problem is my dash lights arent working but my interior light is. Ive checked my fuses and they are all good, ive checked the actual switch and nothing seems to be wrong with it either. Does this sound like the light(s) behind the dash are burnt out? has anyone else had this problem?
my switch is messed up, so if i pull my **** all the way out my dash and parking lights wont work, i have to mess with mine for a while to get it all to work right... a switch is only 20 bucks i just gotta find time to order one

Did you recently change the stereo? The instrument lights, I believe, are all on a common ground. If you check the switch, and it checks good, look for a short in the ground...AFTER you triple check the positive circuit.
I checked the actual lights behind the dash and they seemed fine. Yes i do have tail lights. Nope i havent done anything to the stereo everything is completely stock.... Everything worked completely fine until one day the lights to illuminate my dash stopped working. Im thinking the only thing left to do is change out the whole headlight switch and hopefully this solves my problem.
Sometimes the plug connecting the switch melts and contact is lost.
Replacement plugs with pigtail wires are commonly available in the aftermarket.
I've posted the part numbers before.
The other thing that may happen is that the wirewound potentiometer (variable resistor) at the back of the switch can break, or the little spring metal ear that makes contact with it can break, bend, or otherwise come adrift.
I'd bet on the plug.
Let me see if I can dig up that post.

The plug itself looks fine and nothing seems to be wrong with it. Im going to go to a scrap yard and try and get the whole switch and plug together sometime this week. Hopefully this will solve my problem
I am having the exact same problem with my '91 F250... I believe my problem started one day when I was turning on my headlights via the switch and I heard a tiny "pop" noise followed by a tiny metallic sound as if something like a washer had popped off and fell off the backside of the switch. My headlights still work but no interior/dash lights now. My guess is that I/we need a new switch. Good luck!
