Defrost air will not get warm. Air does not change temp no matter what the dial is set at. All the way cold or all the way hot. I have flushed the heater core replaced the blend door and acuator. I can hear the door opening and closing in the heater box it self. I just got done flushing the engine itself and still nothing changes.
