    2000 Dodge 3500 Sport pickup. My headlights will not turn off. Fog lights and parking lights and high beams work like they should (on/off) but my headlights will not turn off. I removed the headlight switch from the dash and the lights are still on. finally had to disconnect both batteries. Is it a relay that I am missing? Thanks

    sounds like a stuck relay or a bare wire between the switch and the relay,
    I'm not sure on dodge but I think the head light circuit is a switch to ground system, meaning that the switch completes the circuit by grounding the circuit, check for a wire that maybe rubbing a ground source.
    find your relay, remove it and use a meter set to amps connect between the terminals on the low load side of the relay, if it shows amps, you have a circuit completing between the relay connection and the switch connection.
    I do know that dodge has a lot of problems with the harnesses in the truck you have.
    good luck.

    it ended up being the light module for my plow lights (Meyer) between the factory lights and the plow lights. I got a pair of them for $135. i put both new ones in and saved the old, good one for a spare.
