What are the reasons for intermittent cooling in a car's air conditioning system?

[StArya]

The reasons for intermittent cooling in a car's air conditioning system are: 1. Dirty air filter; 2. Damaged blower or air conditioning flap motor; 3. Insufficient refrigerant in the air conditioning system; 4. Dirty radiator or condenser; 5. Faulty air conditioning pressure sensor or evaporator box sensor. The functions of the air conditioning system are: 1. Achieving cooling effect through continuous refrigerant circulation; 2. Drawing in fresh external air for ventilation and air exchange, preventing windshield fogging; 3. Utilizing engine coolant, waste heat, or burner-generated heat as a heating source, warming the air through the heater and distributing it into the cabin via the blower to achieve heating; 4. Removing dust, odors, smoke, and toxic gases from the cabin air, refreshing the air, and humidifying the cabin air to increase relative humidity.
