    My headlights (low beams)will not come on unless I push the Hi beams floor button a few times!?!? Plus, the Hi beam button will not click/lock anymore into the Hi beam setting.....I can only press down on the button to get Hi beams to come on..

    Did u think I need a new floor button? hard to change it?
    does both the low/hi beams power flow thru this floor button?
    any ideas?
    Thx in advance! Mark

    This seems like a textbook worn out switch to me

    Both sets of filaments are powered through that switch.
    Replace it and clean the terminals in the plug with a little file while you have access.

    10 minute job... Get under the dash and do it. ;)

    The switch gets clogged with all kinds of dirt so you could try to just clean it and lube a little to see if it will get to working again. If you are cheap like me. They are usually under 10 bucks to replace with new.

    Chances are the switch is worn out or an internal part is broke and/or the contacts inside may be corroded.

    I would inspect the wiring at the switch and the plug and if everything looks clean and tight, then replace the switch.

    Here is an album of what is inside those dimmer switches from a 60's-70's era GM car:

    I daily drive my car. I have replaced the floor switch three times. I got tired of them lasting for less than 2 years. The one in the car started goofing up. Pulled it out, found the contact plate, the part the wires connect to was loose in the housing.
    I disassembled, cleaned and lubed it. Re swedged over the aluminum so it was tight.
    It has been perfect for about 10 years.
    Make sure the wire connectors and spade terminals are clean and tight. It was common for the connector to get hot and melt.
