Your symptoms sound 100% like the problem I had:

Note, the "flash mode" test should have told you the stock relay was fine.

Replaced both problem solved.

I had the same thing happen to me in a 1986 toyota pickup I owned. I changed both lamps and was good to go.

If you check the lamps, fuses, and rely, and everything seems fine. I think its your switch assembly. Those things are pricey.

Pricey yes, but also repairable. Mine was dead on the high beams, but after a little filling of the contacts, it worked fine. To avoid future problems, I added the relay wiring harness to take the high current load off the contacts there and they have worked fine for nearly 4 years since I fixed the contacts and installed the relays.

Relay kit costs much less than a new combo switch and you get brighter headlights to boot!

I had the same problem on my '91 V6 truck...

first my heater control panel light went out, and a few days later BOTH my headlights went out at the same time... i had to drive home with high beams and noticed the high beam dash indicator didn't work either...

of course i figured it must be a wiring issue, since it would be odd for two headlights to go out at the same time, but that wasn't the case.

after looking through this site i found this thread and sure enough, it sounded like I had the same problem. i figure the low beam healigth circuit is so frail that if something like the heater control panel lights goes, it's a chain reaction.

anyway, i managed to replace both headlights without removing the bumper or grille.
just pop off the top grill pegs and the corner lights to give you some play, then take out the top 2 screws for the headlight mounting bracket and pull the bracket down enough to pop out the lamps. it takes a bit of careful fanagling, but at least your not taking off the fender and grille. could save you lots of time and hassle.

anyway, huge thanks to this forum and all you guys posting, you just helped me out big-time! cheers!
