This problem is likely due to a failed part called the blend door, this door has an electric motor drive, to replace it requires the dash be removed form the car entirely. The blend door is a door that moves back and forth between the AC core and the Heater core to provide cold hot or a blend of air flows from both cores to give the desired temperature. Other issues can cause this and due to the cost or repair a through diagnostic should be done to confirm my guess is correct about the door being the problem.
