Headlights will not come on

I have checked the fuse and even replaced it for the headlight switch
I have replaced the switch but get no headlights. parking lights come on
no high beams either nor high-beam indicator light either. continuity shows bulbs are good. they worked fine until one week ago but were intermitant according to other driver of this 1988 bronco.

I can find no relay to check or replace.

any ideas?

If it is a full size Bronco:

The black w/ orange stripe needs to show 12v + all the time. If it does not, there is a circuit breaker at or around the switch (diagram is not specific) or the blk/org is on a fusable link. so back trace that. The parking lts have a seperate power source, so they would still work. If you have 12v+ on the blk/org, pull on the healight switch and see if there is 12v + on the red/ yellow

If it is a Bronco II ... weird, but the book shows exactly the same colors!? cool!
