Well, you could unplug you AC unit, this should make it stop running. Unless the bearings are seized on the wheel. Then it will keep running. It's the only plug on the top of your AC unit. Regardless the AC unit running all the time should have no effect on your heat. Check you coolant level, and for leaks. No heat often is a result of bad thermostat or radiator cap.
