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.
