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.

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.

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.

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.

Driver side A/C blows HOT air while rest of SUV runs cold. Has happened intermittently and just started blowing hot again.

My drivers side air goes to full hot randomly. Sometimes a restart will fix the situation for a few minutes. I ended up doing a YouTube search on how to fix the "blend door actuator" or "mode select door" and found how to change it. Mine happened to be the easy one located on the passenger side. Due to high cost I just took the actuator apart and cleaned it with acetone and it worked great for several thousand miles. Still looking to replace it, when money allows but it's a decent fix in a pinch.

heat comes out pass side when ac is on. does fine for a time then blows hot. can pull over and turn car off, back to normal.

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.
