    assuming this is a unimount??

    check the following

    Gray wire driver side turn signal
    Check the OEM wire were it connect into the plow harness, driver side and passenger head lights.
    check the black/orange wire it comes off the low and high beam relays

    Check you flasher (or change it)

    It also could be you turn signal switch..

    sorry to bring up an old thread but have not fixed it yet. It's a 3 pin with 4 hookups into the module if that helps. Thanks guys. :drinkup:

    sounds funny to me. is there any chance that you have a buddy that would play a little joke on you?

    Try switching the #3 and the #4 plugs in the module with each other. Sounds to me like somone had a laugh and switched them for you.

    Thanks Philbilly2. It was the 3 and 4 plugs switched. Musta got them switched when it was unhooked fixing some other things.
