While driving with the airconditioning on, suddenly the front air ducks blow extremely hot air. Must turn off the vehicle, then restart for the problem to right itself. According to the posts I've been reading here and on other sites it sounds like a faulty blend door actuator also known as air flap actuator. -
Believe problem to be in the lower actuator. During AC season, passenger side upper and lower vents randomly blow extremely hot air - unbearable for the passenger. Drivers side and rear AC works fine when this happens. I have not found a solution yet other than the $1200 the dealer said would cost to fix. -

Blow hot air driver side, but cool air every where else -

No heat in rear ceiling vents. Just cold air blows. -
