Well, during my afternoon coffe break today at work, I decided to pull my car around back and use our nice aircraft soap and hotsy pressure sprayer to clean the engine bay. Tonight, back at the hangar, I noticed I have no more headlights, can't turn highbeams on or anything. I checked for a blown fuse, but can't find one for the headlights. Tried looking for any wire connections I might have blown apart, but nothing, filament in the bulbs look fine, too. Any ideas where to start looking? Good thing we have almost 24 hours of daylight up here graemlins/thumbsup.gif .

check the dimmer switch at your left foot area, bet the plug came undone there or its crudded up rusty or wire broken. Than can do funny things to headlights.

Ok, thanks, I'll try and check that before I leave town wed morning. If not, where else should I look...? Thanks!

Check that the ground wire didnt get blown off over by the horn relay.

well, replaced the dimmer, and it half solved my problem. either i have only low beams, or nothing at all. can't see any ground wires loose, or disconnected. any other ideas? thanks a lot!

Still can't find the problem...any other ideas?

CB,

I seem to remember having that problem also. I cant recall what it was or how I solved it right now, but I will try to get back to you in the next day or two, if you don't get other replys that help before then.

Wire for high beams broken by chance? or common lead on wrong post.

check the headlight relay on the radiator support.
next to voltage regulator.
Mine filled with water when i did the same thing you did and had same problem until I dried it out then the lights functioned normally.

Dawg - I think you're talking about the horn relay. That shouldn't have any effect on the headlights per-se.
I would check the terminals at the bulbs. Corrosion/loose connection alway seems to be a problem there.

If there is a pair of beams glowing in one position of the dimmer switch and not the other dimmer switch position, then may have a faulty switch.

If the set of filaments light, there's a good ground and supply source. Only addition to the other beam, is a wire, split at the left headlamp to supply the right headlamp, and a pair of filaments.

As mentioned, a broken wire(s), or connection. Maybe the firewall connection needs alittle finesse-ing!
