Headlight switch,brights only
Was fixing the key ignition button and removed the steering wheel cowling and now when I turn on the headlights the highbeams come on.When I pull back the lever to normal lights they don't come on.Don't see any loose wires.Any ideas?

Yes, MLDave.
We know you, and we know you have a Toyota but did you upgrade? LOL!
Seriously,
Pls see signature.
AND How Headlight: Troubleshooting in sticky applies to 4Runners up to 3rd-gen US model (no DRL).
So High beams always work when selected?
Low beams never work when selected?
Hazards work?
Bulbs good?
I bet low-beam contacts are bad. the poor wiring of the headlight circuit (google "convoluted path 4crawler") caused that AND our dim lights.

That's what I thought.
OK, Headlight: Troubleshooting in sticky applies to 4Runners up to 3rd-gen US model (no DRL).
Select low-beam, SHORT low beam pin of combo switch to ground. What happens?
Short low-eam pin of headlight connector to ground. What happens.

Cool, Dave.
It's usually just pitted contacts. You can build up the pitted spot with solder. I've done it with our 87 Prelude that I think had similar poor wiring design. After fixing the switch, use H4 conversion harness or wire in ONE relay like I did (on my thread).

I checked the wire against a spare headlight combo switch and it's a red wire/green stripe and it also is soldered to a small piece of copper.I don't know much about any of this except what I see.
