I would go to the high beam switch next (test not replace)
either a blown fuse or bad headlight switch
You have a broken wire.
You didn't mention if you checked/tested the low beam headlamps or not.
You more than likely need to replace the headlight switch. Lights not going out when turned off is a symptom of a bad headlight switch.
the headlights and the tail lights will not turn on when i press the switch, also the dash will not light up like it it suppost to. i checked everything except the wiring. what is the best place to find headlight specific wiring diagrams?
It really needs to be checked out but it probably is the headlight switch itself that is malfunctioning.
I just had the same problem in my '97 Nissan pickup. Both headlights stopped working at the same time. I went through some hoops, including trying a new headlight switch, but it turned out to be some corrosion in the plug for the fusible link that bolts onto the positive terminal of the battery. I cleaned that out and it is working fine again.
i have a 96 olds achieva and my high beam light was flashing, i checked the headlights and one of my low beam headlights was out. once replaced the flashing stopped.
Is it possible one headlight has been burned out for a while, and the second one going made you notice it? If not, I would suggest the headlight switch as the next most likely part.
It is a sealed unit housing the bulbs. If it shows water beads or collects, it needs to replaced or removed and checked for damage. The only thing you can do besides replace the unit is drill a small hole under the headlight unit in the middle.This will allow the water to drain. Which may save your bulb.
Are both low and high beams out?
WHAT ARE YOU DUMB REPALCE YOUR LIGHT BULBS STUPID! Not stupid replaced circuit boards checked fuses ran test light . When headlights are on no brake light or taillights and have all new bulbs stupid. Turn headlights off brake lights work, so figure that out smart man
