The air conditioner compressor or temperature sensor is faulty. The car air conditioning system consists of a refrigeration system, heating system, ventilation and air purification device, and control system. The functions of the car air conditioner are: 1. Using the continuous circulation of refrigerant to achieve cooling effects; 2. Utilizing the engine coolant, waste heat, or heat generated by a burner as a heat source for heating through the heater, with air blown into the car by the blower to raise the temperature at the air outlet for heating purposes; 3. Drawing in fresh external air for ventilation and air exchange, which also helps prevent windshield fogging; 4. Removing dust, odors, smoke, and toxic gases from the car's interior air to freshen it, and humidifying the interior air to increase its relative humidity.
