The reasons for the air conditioner not blowing hot air are: 1. The heater core has malfunctioned; 2. The water valve of the heater core has malfunctioned. The car air conditioner heating system utilizes the engine's heat. The functions of the air conditioner are: 1. To adjust and control the temperature, humidity, air cleanliness, and air flow inside the compartment to an optimal state; 2. To provide a comfortable riding environment for passengers and reduce travel fatigue; 3. To create good working conditions for the driver and ensure driving safety. Precautions when using the air conditioner include: 1. Choose an appropriate air conditioner temperature; 2. Do not immediately activate the internal circulation when entering the car in summer; 3.

What is the difference between internal circulation and external circulation in a car?

The difference between internal circulation and external circulation in a car is: 1. The indicator for internal circulation is an arrow pointing inward; the symbol for external circulation is from outside to inside. 2.

The methods for using car air circulation are: 1. Use internal circulation during traffic jams and external circulation during high-speed driving; 2. The use of internal and external circulation should be combined with air conditioning and heating; 3. Use external circulation during long-distance driving to allow fresh air from outside to enter the car, avoiding excessively low oxygen levels inside the vehicle.
