I am not sure if my son installed it properly, if he did not... would it still blow air? My air conditioner was working before the last climate control broke, within 2 weeks we ordered one from here. The climate control we received from here, the air conditioner does not work, only very hot air blows out no matter what setting it is on even the heater setting is very hot, no matter what temp. and it will not blow cooler out side air in either. ugh maybe I have to take it to a repair shop? I hope my son can figure it out.
