Man when it rains it pours with my son driving the 85 4Runner. The low beams do not work but the high beams work on flash and fixed mode. I have changed the relay and that didn't work. I've now taken apart the combo switch and tried cleaning the contacts per 4Crawler's webside advice. To be honest, all the contacts looked clean as in almost brand new clean. I'm going to start chasing voltages if I can but thought I would post in the meantime to see anyone has any suggestions. Most of the headlight problem threads are problems with the high beams and cleaning the contacts worked.
