    I drove last night and my headlights did not work, but all the other lights did.

    When I kick the high beams on, everything works...including the low beams.

    What the heck is goin on?

    yes. Tonight I finally got to putting the headlight switch in my car and when I pulled the switch on no low beams or high beams either.I wiggled the wire that goes on the switch and took the 2 screws out of the floor that held it down and then it started working.I think I need to get me a new dimmer switch too.

    I also had a problem a few years ago with my Regal.I had all the lights except headlights. Seems the wires that hooked to the starter corroded off and lost contact.

    Had that problem also once.
    It was the dimmer switch.

    New dimmer switch...that's not it.

    I can hear the main switch shorting out when I turn the lights on. Can you buy these at the auto parts stores??

    Crap....:mad:

    I think you can get them through some parts stores.
    Worth a phone call.
    Of course, the age of our cars always works against our luck at parts stores more and more.
    Any donor cars in any junkyards near you?

    It's not the switch as far as I can see...

    One of the wires coming from the switch is completely toasted. Now I get to trace it back to the ground and resplice.


    ARRRGH car show tomorrow too!!!!!

    the headlight switch making so much noise is probably because the dimmer switch is shorting ALL of the headlights on at once .... the headlight switch is not designed for such a load.... it is like the headlight switch is crying for help ... your dimmer switch is the ONLY switch that can connect the brights and dims together unless you have a wiring/re-wring problem somewhere ... which is un likely due to your cars symptoms.
    try a different dimmer switch

    my guess would be that the burnt wire used to be light blue.

    I also think its the dimmer. Same symptons when it went on my '78 Impala. All I had were brights or nothing. Ofcourse that one was mounted on the column, but when I took it out, you could see the contacts inside were all burnt out.

    Dimmer switch was swapped. Still nothing. I just bought a new headlight switch. And I'll be fixing the toasted wires under the dash. Kill me.:gt:

    :gt: ugh!
    I know from experience under the dash of the Electra I owned that you could use a couple extra joints in your arm to comfortably get at that headlight switch.

    Check your grounds for the headlights...if memory serves, there's only a ground for the brights on each side, right? The hi-beams only have two prongs while the low-beams have three?




    o wow, howsabout a late reply


    This sorted out yet, Adam?

    Yes, I'm glad you brought this to the top!

    I had replaced the fried wires behind the dash.. It took me about 6 hours to do this from tear down to button up.


    I finally tracked the headlight wires in the engine compartment and found that I had screwed through one of the wire clusters.:Dou: This was when I installed my new carpet and decided to run an amp for my stereo. I screwed a screw into my fuse block for the 30 amp inline fuse, and never realized the wiring harness was right behind the core support!!!

    Fixed now....stupid stupid...

    Well at least you figured it out yourself!

    Two summers ago I pulled my front clip to detail the engine and core support. When I put it back together, my headlights wouldn't work...when I honked the horn the relay would click and my right directional came on, and when I used the directionals, the hazards flashed- it was like Greg Brady's car, remember when he re-wired his crummy car on the show? The rear half of the harness worked fine, though. I tore through everything. I removed the front and main harnesses and checked every connection, every connector and every wire. I replaced my dimmer switch, the horn relay, the headlight switch, heck I even put in new fusible links...I was about to get some gas and a match when, while mucking about with a fender, I saw a ground wire...well, half of one. Somehow, while bolting the fender to the inner fender, I clipped a ground wire for the headlights just enough to pinch the wire in two:Dou: So don't feel too bad!
