    my 2005 2500hd headlights both quit working last night. Worked fine, shut truck off to run in store, come out and have no headlights. I do still have marker lights and blinkers.

    I swapped out the dash switch with my brothers truck and that is not the problem.

    Any ideas if there is a relay or module somewhere?

    I checked all wiring connections that I know of and everything is tight. I checked on some other forums and it sounds like there is a module in the collum that can go bad, or it could be the body control module (BCM), .... anyone had this problem and was it one of those fixes?

    I have no lights at all, not high or low beam, nothing but markers.

    Fuses are good. So are the relays, I swapped them out with the AC relays(same part #) and it still works.

    Got the Haynes manual out now...
