My air-conditioning unit runs constantly. I can't get any heat at all. I was told it could be a relay or the switch in the dash. I am not a mechanic and cannot afford one. How do I go about checking these two things. I know where the relay is, but I'm not sure what I'm looking for in a problem. The switch I have no idea on. All I know is how to take out the dash unit.

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.
