I searched and found but no match.
Pass door activates all lights. The driver's door turns on no lights. Hasn't worked since I've owned it.
New light switch installed because dash lights weren't working. Installed new door jamb switch to no avail.
Any help? Link to a fix?
Thanks.
Edit: 1992 f150... Sorry

A wiring diagram would help you a lot. You can use a meter to find out what the readings should be by measuring the pass side switch. Then compare drivers side. Probably follow drivers side switch wire till you find a connector and check there. It could be broken inside the insulation.

Test light - follow the power and find out where it stops.

A diagram would tell me where SUPPOSED to go from the switch.
It all works, just not on that switch. I'm thinking that means there's likely no power going into the switch.
With the 3 wires, anybody know which is in, out, and (ground, I guess)

Toid

Between poor light and poor eyes, I have a black/? wire, a red or pink wire and a green/yellow wire.
I read (but with little confidence) that the red wire powers the chime, the green/yellow wire should be hot, and I confirmed the black wire becomes hot when the courtesy lights are turned on at the switch.
I have found no diagram.
Any info on the circuit / ID of the wires on the switch? Fusebox is all good. If I've lost 12v from a pinched wire, I can run & fuse a line myself to the switch but I need to know in/out.
I cannot find my continuity light

You're checking the little button that the door closes against right ?

Toid

Yes. The (interrupt?)switch.

Some of those switches are wired to ground the wire that is connected to them, completing the circuit. Some are wired between the fuse and the light to complete the 12V part of the circuit to the light. That is one reason a wiring diagram and meter would help troubleshoot.
