No Dash Lights or Dome Light.
My 82 F-150 doesn't have the dash or dome lights working anymore.
The dash lights quit about a week ago, and the dome light a few days afterwards.
I've replaced the headlight switch, and checked all the fuses, and it still doesn't affect them.
Im at a loss as for what could cause this....anybody got any ideas?

Off the top of my head, I'd maybe think it was the dimmer switch on the floor. Do your headlights work? If I remember correct, the headlights and dashlights have to physically/electrically go through that switch first, although that wouldn't explain the interior lights. (???)
Do any of y'all know if the interior lights go through the dimmer switch too?

I've got heads and tails, when i swapped the headlight switch, i checked it with a multimeter, and i have 12 volts coming from 3 wires on the switch connector.
I don't think the interior lights go through the dimmer switch on the floor, but its possible.

I am sure you checked your fuses, but I thought I would mention it anyway. If you look at the diagram below(which isn't that great by the way), you can see the courtesy lamp circuit goes along the tan/white wire and into the light switch.
If you look at the lower left of the diagram you will see the fuse and lightblue/red wire that goes to the light switch, and then feeds the instrument lights. I don't know why they don't show it, but this wire would go through the light switch, and the rehostat in the switch for instrument light dimming.
It all still seems to point to the light switch, though I wonder if it's a plug or socket problem in the harness that goes to the switch?
By the way, the dimmer switch to the headlights doesn't affect the instrument or courtesy lamps.

As it turns out, the circuits that power the dome and dashlights are completely dead. I've checked them both with my multimeter.
The Red&Blue wires are dead at the switch, and the black and blue wires are dead at the switch also.
I'm even more puzzled now than i was before, because everything in the fuse box is good..the switch is new and all the lights in the dome and dash are all new and good.
Anybody else got any ideas?

Check the LG/Y wire coming off fuse #7 - it goes to the main light switch, engine compartment light, clock, glove box light, door switches, and dome light and should be hot at ALL times.

Thanks for the insight guys, but for now i've got those two circuits bypassed.
i removed the little light that lights up your windshield wiper/headlight indicator when you have your headlights on, and connected it to power, and my dash lights came back on. So i just ran the wire from there up to the toggle switch that controls my cablights.
As for the dome lights, i just made a jumper wire from one of the hot wires to the dome light yel/green wires, and now they work when i open the doors and when i turn the headlight switch to turn them on.
Yes its rigged, but for now its working.
The headlight connector has been cut out and spliced in from a different vehicle, of what i have no idea, but none of the wires match the truck's harness on further inspection.
The connectors that control my dash/dome lights are loose inside their sockets, and i'd assume thats whats causing the problem. I'll go to a boneyard and find me a plug that matches mine with the correct harness and swap it in.
