a/c clutch is cycling when heat is on. I'm not talkin defrost just regular heat.

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...

Yeah what Mike said:tongue:
