Re: 39 Headlight Dimmer Switch

Just had mine out as, when we removed the front end clip, we had to disconnect the headlights and signals; then when we went to put things back together, found issues like you are referring to.
We found the only way we could get things to work properly was to use the second position of the switch (first is parking lights only) and the third made the driver headlamp go bright and dim but not the passenger side. According to your description, maybe that is how they're SUPPOSED to work???

The dimmer switch can be easily removed be taking out the 2 slotted screws in the floorboards and pushing the switch outward. Then if you go under the hood you can reach down and grab it and all the wires are accessible. Mine is 3 contacts, 5 wires, with one contact having 3 wires. I believe the 3-wire contact is the switch leg with 2 wires going to the respective headlight pots. My switch was okay, but I have replaced lots of those floor switches over the years, as they get moisture in them from snowy boots, etc., and corrode. Holes in floorboards don't do them any good either! LOL Been there...
Grounds were also an issue with my wiring, so be sure and clean all your ground contacts. Good luck.
