    Hey guys 06 Columbia. I’m having issues with my right blinker staying on with headlights. So when I turn on the passenger side turns/blinkers stay on. With headlights off , right blinker on , looks like I have my hazards on . I swapped out the 7 plug/wire . Nothing . I cut the wire for the pass blinker after the 7 pin but light is still on . any suggestions

    Go through all your fuse boxes.
    Check every fuse that controls the lights
    For both the tractor and trailer.

    This is a ground issue somewhere. It could also be inside a light. Pay special attention to any lights with a cracked lens.

    Try taping the side lights on trailer with headlights on and look for any changes in lights, tap the turn sig. Light on rear. Use the spare light you should have in your tool box and change the side lights and the rear turn signal light, til, you find the light that is shorted out?
