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
Here's a pasted response that I gave in trucks and trailers thread.
you really only need 1 post, then give it some time.
If what I posted don't work let me know, there is a number of possibilities.
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.
