if you are not hearing the blower motor blowing, but just kinda getting a trickle of warm air, its probably a result of your heater box needing to be redone. Basically there are flaps in there that keep the air from traveling through the heater core. When they get damaged or whatever you will get hot air.

wait, is this a car with AC?
