This may be an inoperative blend air door. The blend air door directs the air flow through the heater core and the a/c evaporator, so if the door is not working the A/C system may be functioning properly, but the air will be flowing through the heater core.
Thanks that is what happened I took of the blend air accuator and turned the door manually works great
HOW DID YOU TAKE THE DOOR OFF ?
