Hey guys I hope you guys can help me casue electrical is one thing that i dont have the patience to figure out if I dont have to. I was drivin home the other night and i met a car and hit the floor switch to my dims and when I went back to the brights the light on the dash came on but my brights didnt my headlights went out. I went back to dim and they came on as dims. I have new headlights installed, new pull out switch, and new floor switch. I stuck guys help!!! the headlights were the only problem ive had when that happened. I did tear into my wiring harness last nite and tonite because I had a slight electrical fire down at the starter(burned the power wires off but not the battery cable. I got that problem fixed and shortened the wires so they wont touch my headers again, but im still stuck on the headlights. any help will be great guys.

replace dimmer switch

Hey I replaced the pull out switch and the floor(dimer)switch and still didnt help I think its in my wiring

I gotta agree with downs, as I've had the exact same symptoms, and a dimmer switch fixed it every time. Your new switch may be bad. You can try testing the switch by: pull the connector from a headlight, and hooking up a volt meter.

i agree with the other's but make sure if you replaced dimmer switch that the wiring connector is pushed on dimmer good and tight,,also play with connection on bulb's,,make sure there all good and tight.i have had BOTH problems do the exact same thing..:)

hi guys thanx for all your input so far i have tried everything you have sid to do and its not helping my problem any. I tried just direct wiring without the dimmer switch and it did the same thing as with the switch im stumped. Ive followed wires looking for breaks or cracks in insulation finding nothing. Ive jiggled the wires under the dash and checked all my connections im stumped.

well check the bulbs out with an ohmeter and see if the hi beam filaments are good if they are check the plug that goes on the headlight if theres 12n to the hibeam positrion if not go to the dimmer switch and see if there's 12v coming out of there that should tell you where the prob is

sounds to me like something burnt out both high beams,,i would replace one of them (again) and see what happens if you have checked everything else.

Dont know if you figgered it out yet, but I had the same thing happen to me. Turns out all of the rear end brake lights, turn signals, reverse etc were cut, torn and shorting out. This burned out my headlights and every other as well. I would guess that one of your other lights wires is shorting out.

That seems HIGHLY unlikely, the headlights aren't on the same curcuit as any other light on the truck.

Ensure power is getting to the headlights, and if so,a last ditch affort would be to remove the small wire that grounds to the rad core support on both sides... not liukely, but still a posability... then replace the headlights. Power to the lights with agood ground....would leave the lamps as the only thing left.

Hey guys I fixed it! the problem wasn't where anybody had said at all which is partly my fault. i had said I checked the wiring harness, well that was just under the dash. I did the volt meter trick and traced it up to the connection where the highbeam wire splits to go to the headlights on the rad suport, wiggled it and lights came on so I reworked it and now it works like new and i have a new dimmer switch and light switch:) . Thanx for all the input it was greatly appreciated.
