Sounds like you have a leaky heater core. You will need to replace the heater core and give the cooling system a good flushing, it shouldn't be rusty.

Why would a 1989 Chevy Silverado 350 heater only put out luke warm air even after changing the thermostat and back flushing the heater core?
I had the same problem. The answer to your problem is simple. You have an air pocket in your cooling system. Simple fix - take the radiator cap off of the radiator, turn the vehicle on and let it run for 1hr to remove the air from the system. Also, make sure your overflow container is atleast at the minimum level. Answer If your certain you have all of the air out of the cooling system the blend door inside the heater box may be stuck open.
How does the heater control valve operate?
It partly depends upon what sort of heater it is, but if it's a car heater, the valve alters the amount of hot water (from the car's cooling system) entering the heater matrix. This would also be true of a water-filled central heating system.
Heater problems 2000 GMC sonoma 4.3 vortec?
If all the inside controls are working and you have antifreeze in the cooling system them I would suggest that you check and make sure that the thermostat is working and after that check to see if the heater core is stopped up. If so then you will need to completely flush out the cooling system including the radiator, block, all hoses and the heater core.........

Your 2003 Galant will blow air but no heat why?
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.
