Default trouble shooting suggestion

If truly blowing hot air like you have the heat on then this is most certainly a problem with one of the blend doors (likely the servo went but could only be the pcm that you change the temperature with or the door got stuck). If is not hot air like when the heat is on the blend door could still be the issue but I would also confirm that your A/C is engaging. You will hear a click from the engine when this electromagnetic clutch engages and another one when it disengages. The servos that control the blend door(s) one door if not auto climate and two doors if it is are located behind the center stack that houses your radio and temperature controls. The mode and recirculation doors are located behind the glove boxes.
