When you turn your heater on does it blow out warm air? Or does it just make a funny sound, and no air comes out or warm air only come out one side? This could happen for a couple of reasons. It could be that your blower motor is not working, your blend air doors are stuck in one position or maybe a varmint has taken up residency in you blower motor.
