If the blower motor is working, make sure the coolant is full. Also, check to make sure the engine is warming up to a normal operating temp. Next, if that all seems normal, start the engine, let it warm up with the heater on high. Feel both heater core hoses. Both should be hot. If they are, check and repair the blend door. If only one is hot, flush the heater core.
