Generally, it is due to a blown fuse in the resistor, and replacing it should resolve the issue. Below are the functions of a car's air conditioning system: 1. Temperature Regulation: This is the primary function of a car's air conditioning system. In summer, the cooling system generates cold air to lower the temperature inside the cabin. In winter, except for large commercial vehicles that use independent combustion heaters for heating, most vehicles utilize waste heat from the engine for warmth. 2. Humidity Regulation: Humidity significantly impacts passenger comfort. The humidity inside the cabin should generally be maintained between 30% and 70%. Standard car air conditioning systems do not have the capability to adjust cabin humidity; this can only be achieved through ventilation systems or advanced luxury vehicles equipped with integrated heating and cooling air conditioners. 3. Airflow Regulation: The speed and direction of airflow greatly affect comfort. If air is blowing directly, the speed should be limited to a certain range when the temperature is appropriate. The airflow speed can be adjusted based on passengers' living environment, age, health status, and temperature preferences. 4. Air Purification: The quality of air inside the cabin is crucial for ensuring comfort.
