Ok, So up until now my headlights and everything have been just fine. I drove to work today and shut off my lights on the switch. but they stayed on, headlights shut off but instrument, marker and tail lights wont go off without me pulling the fuse. I pulled the relay out cleaned it up, put it back in and I can feel/hear it clicking but still stuck on. If I check I have 12V of power constantly at the fuse and relay. Does this sound like a headlight switch? Will that make them stay on? I'm pretty damn confused at this point and not real sure what to do. If it is the switch how do I pull apart the column and check it?

 

oh yeah it is a 1991 toyota pickup SR5. manual, 6 cylinder. Bone stock electrically speaking

 

Disconnect the headlight and turn signal switch at the connection underneath the steering column.

See if that cures your problem .

It would need to be in the parking light side of the switch as the head lights do turn off.

You pulled the cover off the relay and cleaned the contacts making sure they were not stuck closed??

 

Yeah even got a new relay. Kinda stumped...

 

You tested the switch by disconnecting it under the dash? And the lights still stay on?

Could be a short in/near the integration or reminder relays.

 

So... This is weird... Unplugged the switch, lights go off. Plug the switch back in, light switch working like normal... Not sure what caused it to work.
