High but no low beams on BII

[BatlinSI]

I've got an '88 BII, and I've got no low beams. They worked fine one day, and then wouldn't come on the next. The high beams, and all my other lights for that matter, still work, and for a little while, probably as long as two weeks, I was able to flick the high beams on and off a few times and the low beams would come back on. Now I get nothing.

I changed the switch (the old one was petering out anyway) and checked all the fuses and bulbs, but I've run into no solutions thus far. Any and all help would be appreciated in this matter...

Using a test light, follow the low beam circuit from the switch to diagnose the problem. Rd/blk wire. The low beams use a fuse in the form of a resistance wire after it leaves the switch if the truck has a lamp out module.shady
