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.

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.

Heater was coming on in the summer with the air blowing now winter heater will not come on at all.

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.
Air conditioner blowing warm air on drivers side cold air through other vents
Blowing hot air out front vents when ac is on...replaced actuator to no avail...replacing HVAC control module...have to drop the whole damn dash...smh
turned on ac driver side blows hot but all other vents blow ice cold
Ac blows extremely hot air. Refrigerant is full condenser is working
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.
hot on driver's side, freon topped off
Rear heat dose not work. Cold air comes out but front heat is fine
No heat in rear ceiling vents. Just cold air blows.
