One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

front & rear a/c blowing warm air clutch cycleing, short cycleing switch,add refrigerant, the only line that feels cold is the liquid line entering the evaporator and that is with the accumulator switch shorted.

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.

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

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.

When the AC is on sometimes hot air blows out of the driver side vents and at other times hot air blows out of the passenger side vents, but the rear vents always blow cold air. I have to turn the vehicle off and back on to reset it but it eventually does the same thing again.

Heat comes out of one side and cold out of the other gents. Will get the codes checked to see if it's an actuator door failure and if there are any software updates.
