Headlights not working and I already replaced the switch
 

I replaced the bulbs, the fuse, the switch, and the dimmer switch (whatever the one on the steering column is called). They worked great after I replaced all of that, except that when using the brights the headlights would eventually shut off. Turning the lights off, and back on would fix it.

Last night the headlights just went out completely. The only way they worked was if I held the brights on. If I sat and turned everything off for a couple minutes they would work for a bit again. Based on this I decided to do a search for a headlight relay, well I guess those don't exist and everything goes through the switch that I already replaced?

So what is the next step?

Thanks in advance,

These are from my '97 FSM but maybe they can help with your '96. (With many thanks to member "salad" for showing how to upload FSM pages.)
