Low coolant in the system. Defective heater control valve. Clogged heater core.
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.
Could be a bad thermostat.
heater control valve is bad on the drivers side.
Probably leaking freon.
You have to get it recharged. you have no freeon left which makes the cold air
You might need freon
either need a blend door accuator or a heater box
