1. Material: The resistance of the car blower motor is made of ABS material, which is small and sensitive. It is durable and stable. 2. Functions: This blower motor resistor for AC fans controls the fan speed of the vehicle's air conditioning and heating system. If you encounter issues such as the AC fan running at a fixed speed or the air conditioner not blowing at all, replacing our blower resistor may solve the problem. 3. Installation: Our blower motor resistor kit is a direct replacement, and the resistor module is mostly located on the lower passenger side. Simply remove the screws securing the resistor, take out the resistor assembly, and install this product in place. 4. Quality Control: The car air conditioner blower resistor has undergone strict quality and functional tests before leaving the factory, is suitable for various harsh working environments, and is an accessory!
