1986 toyota SR5 pickup

my headlights are inop, i have installed two new headlamps and tried a new headlamp switch. my flash to pass works but my high beams and low beams are inop, any thoughts?

Check the headlight relay.


if the relay was bad wouldn’t my flash to pass be inop too or is that a different ground circuit

Don’t over-think it. What sounds easier? Checking the relay and it’s socket? Or tracing the wiring harness?


thanks i’ll try a relay

Hint: look for the relay in the relay box under the hood, near the battery. It may be the same as other relay. You can swap the HD relay with another…maybe the horn relay.

thats the only relay like it under the hood, i may have to go buy one and try it out.
