I would suspect that the heater core is either clogged or the heater temperature control valve is defective. Have you ever serviced the cooling system? It is also possible that the thermostat is stuck open. I would drain and flush the cooling system. Install a new thermostat, install a fresh 50/50 mix of the correct antifreeze and distilled water. See what you have before proceeding any farther.

Why does the heater not blow air?
The heater does not blow air because it emits infrared rays that have heat molecules within them, thus releasing heat, not blowing it. A heater does not blow air becasue there is no moving air source within the heater. The heater emits infrered rays that cause heat to slowly flow out of the heater.

2003 Mitsubishi Galant have no heat and blow cold air?
the most common cause of this is your engine coolant may be low. If this is the case then there is not enough of it to pump through your heater core (the coolant is hot from you engine, it is pumped though a serise of tube-like things similar to a radiator and then air is blown across it to make the air hot). That or your heater core itself may be broken in wich case it cost about 100-200 with labor to get a new one.
