Had a Fubar with the '83
 

Okay folks -
last night after leaving work I lost all my parking lights, gauge lights and tail lights; AND had a lovely encounter with a local police officer who told me about it ha!

Changed out all of the fuses and nothing was cooked, swapped headlight switches and that didn't do it either - still no lights.

The headlights work perfectly fine, and when ya smash the bright light switch on the floor it does illuminate the light bulb on the dash...SO, Something else has gone wonky and I'm about clueless where to start so I figured I'd see if anyone else may have had or is currently having the same issue.

When you changed your headlight switch, was the plug cooked?

Take your headlight switch out and try to test your plug, kinda like this: Part 1 -How to Test the Ford Headlight Switch

You just run a jumper to different slots and see if your lights turn on.

Did you TEST the parking light fuse? Did you check the new fuse to see if it's blown?

Take the drivers side kick panel off and check in the top of it for a bad wire. There's a really small (can't remember the color) wire that melted on mine in a spot, reconnected it and they've been strong ever since.

​​​​​​​You're parking lights also get power to the switch from a different wire than the headlights, I would give the fuseable links under the hood by the passenger fender a check.
