Posted December 12, 201014 yr a/c clutch is cycling when heat is on. I'm not talkin defrost just regular heat.
December 12, 201014 yr Owner The only positions the A/C should come on is... [*]MAX A/C [*]A/C [*]BiLevel [*]Floor/Def [*]Def Now as for Vent and Floor those will not trigger the A/C... But the nice part of running the A/C is that the A/C is cooling the evaporator drying the air as the moisture freezes to the evaporator. But since the in comnig air is so cold the freon pressure fall rapidily and the A/C cycles off. This causes the evaporator to warm back up and thaw draining the moisture outside. This just makes life nicer in the cab...
