• model: Voltage is adjusted by resistors Compatible With voltage division or through knobs to change the motor speed (such as low / medium / high three-speed air volume)
• During cooling: The fan blows the cooled air from the evaporator into the vehicle, while also helping to dissipate heat from the evaporator. When heating: In combination with the heating water tank, the heat from the engine coolant is transferred to the cockpit.
• Defogging mode: Usually automatically switches to maximum air volume + external circulation, quickly removing the fog on the glass.
• The air flow fluctuates greatly or is completely absent: This might be due to motor failure, poor electrical contact in the circuit, or damage to the resistor.
• Only the top gear has wind: This is usually caused by a damaged airflow control resistor (Compatible With the top gear, bypass the resistor and supply power directly).
