It can prevent poor connection, prevent excessive current from burning out the blower, ensure efficient operation, and extend service life.【Function】: The blower motor resistor controls the fan speed of the blower motor by changing the resistance. If your blower motor is stuck at a certain speed and the fan does not work under certain settings, the vehicle ventilation port will not blow air. This blower motor resistor can perfectly solve this problem.【Package Includes】:1 X HVAC Blower Motor Resistor, 1 X AC Blower Control Module Wire Harness
