high beam relay
Bad headlight switch or both bulb high-beams are blown. Could also be a bad connection under the hood. I believe there is a connector on the drivers side fender than tends to corrode. Best bet either way is an aftermarket headlight harness which takes the load off the undersized wiring.

Nope, no factory headlight relays.
If lows work, the switch must be OK.
If the flasher function works, the bulbs are good.
How did you check the dimmer switch?

Tks for reply. New dimmer switch. I don't understand comment about flasher? Will check for underhood connector. Going to verify headlamps good. Then take multimeter & work from headlights to dash. This vehicle is "new to me", so who knows what I'll find as problem!

Sorry, we maybe into the "2 countries separated by a common language" thing. What we call the headlight flasher & I believe you know as "flash to pass" is (like on most everything) is operated by pulling the dimmer switch lever towards you, the high beams will then be on for as long as you hold the l lever in that position. If that works then the bulbs & their wiring are OK. Just an easy way to narrow down the cause of the problem.
