Why does the air conditioning fan of Ford Mondeo not work?

Ford Mondeo's air conditioning fan not working may be due to insufficient battery voltage and lack of power. When the car battery voltage is low, usually below 12.4V, it is considered severely depleted. In this case, it is advisable to use a portable charger to recharge as soon as possible, as relying solely on the car's alternator for charging is very slow. The following are the functions of a car air conditioning system: 1. Temperature regulation: This is the primary function of car air conditioning. In summer, the cooling system produces cold air to lower the temperature inside the cabin; in winter, except for large commercial vehicles that use independent combustion heaters for heating, most other vehicles utilize the residual heat from the engine for heating. 2. Humidity regulation: Humidity significantly affects the comfort of passengers inside the vehicle. The humidity inside the cabin should generally be maintained between 30% and 70%. Standard car air conditioning systems do not have the capability to regulate cabin humidity; this can only be achieved through ventilation systems or advanced luxury cars equipped with integrated heating and cooling air conditioning units. 3. Airflow regulation: The speed and direction of airflow greatly influence passenger comfort. If the 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 condition, and personal preferences regarding temperature. 4. Air purification: The quality of air inside the cabin is crucial for ensuring comfort.
