When I turn my heat on it doesnt blow out hot air, the air it blows is just air not hot or cool. Also my air conditioner works fine. So what could it be?

Do the heater hoses get hot? Does the engine reach normal operating temp? Are there any hvac applicable trouble codes? Might be an actuator door under the dash, that isn't working properly?

It isn't 30 degrees F below zero in your area?
