    I see this has been asked but still need help.
    2013 Western Star DD15.
    Fan runs all the time. Fan clutch is 7 months old. Moves in/out when firing up the truck...fully aired up.
    Disconnected air going to clutch, but fan still runs.
    Could this be a broken wire and/or ground? Sensor?
    Looking for advice on where to look next.
    Thanks.

    Could also be the high pressure switch on your a/c. jam a paper clip in it and see what happens. This can turn ugly really quick.
