: If you can turn on the heater but only cold air comes out you should check the blend door. It controls the door to switch from cold air to hot. It sits directly behind the heater/AC controls. It is white square plastic piece (approx 3in x 5in half inch thick and has a plastic screw rod that attaches to the heater/AC controls and they strip out. Hope this helps.
