I have replaced the compressor and the control panel on the dash. when the mechanic replaced the freon it blew cold until i turned the car off then it returned to heat and wouldn't blow cold. I have also replaced the motors that control the flaps in the dash. the controls do not seem to be able to make the switch from air to heat and back to air.
