I was being a smarty. The air conditioning system in you car does 3 things to the air. Cools, cleans, dries. You can use AC and heat at the same. AC isn't just for making cold air. What are the temperature readings at the inlet and outlet hoses. What are the readings from the heater core lines. If the temperatures check out ok then move on. Have you checked to see if your heater blend door is mechanically sound and functioning properly. If it is not, is the blend door motor bad, the blend door cracked or is the motor not getting a signal from the head unit? If you can get those readings and answers I can tell you exactly what is wrong with your heating system.
