The heater runs non stop, doesn't matter if its on high or low. It seems to be worse when the truck is accelerating, pressing on the gas pedal. We have tried putting it on the a/c side and it stills blows just as hot, and I mean really hot. We have checked fuses & other things but can't find anything that would cause this.
