i'll try to make this as simple as i can...

WHAT I DONT HAVE:
-rear running lights
-any marker lights (corners, license plate, etc)
-instrument panel lights
-heating & AC lights

WHAT I DO HAVE:
-headlights
-high beams
-turn signals (front and rear)
-dome light
-fog lights
-break lights

i have swapped out all the fuses, and replaced my headlight switch (that also acts as the dimmer switch) with a brand new one. it still did not fix my problem, so does anybody have any idea of a specific connection that could be loose? or am i just going to have to dig for a needle in a haystack?

any help is appreciated

Have you checked any of the bulbs in question? I know it sounds ridiculous but ive seen it happen before that one bulb can go bad and affect all the others if they are on the same circuit. I have also seen a bulb socket in a tail light go bad and burn up and throw the lighting system off.

check the dimmer switch too...could be the reason for the interior lighting issue

i checked bulbs and the headlight switch acts as the dimmer switch as well, which has already been replaced

any sockets looked damaged or corroded or anything when you checked the bulbs?

Ford and Chevy made some very, very large haystacks in the 1980s. LOL. Good luck.
