the problem is caused by the motor that operates the air temp blend door motor in the heating ducts, it blends air between AC and heater core tro give desired outlet temp.

Here's the thing. The ECU will shut down AC if the engine temperature is too hot. If the coolant temperature sensor is malfunctioning (lying to the ECU) telling it that the temperature is hotter than it actually is, the computer will turn the AC OFF.

It's possible the cooling system is just a little low on coolant. There could also be a valve in the heater hose that is failing to open and let the coolant flow through the heater core. It could also be the heater core itself. Did it start doing this gradually or did start all at once? If it came on gradually it most likely the heater core or low coolant, if it happened suddenly it's a valving or heater control problem. Good Luck.

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.
