SOURCE: heater doesnt blow hot air out
Check coolant level. You may have lost coolant. If so, usually, leak is due to worn water pump seal.
Also, make sure that you have vacuum to move flap, so the air will go through heater core.

check your coolant levels first then if you have never replaced the thermostat replace it. there are several other things to check, proper operation of the damper for heat, does it fully close? Heater control valve, does it open fully. and several others but these are listed in order to how i would check this problem out. Merry Christmas, and hope this helps you.
