Check the heater control valve. Make sure the heater core isn't blocked. Make sure the blend air control doors are actuating properly.

If the coolant is flowing through the heater core and the blend doors are opening and closing properly and it isn't blowing warm, I don't doubt that it's possessed.

Make sure the hoses leading to and from the heater core are warm when the engine is hot. If not, determine why not.
