【Blower Motor Resistor】 The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. It is responsible for controlling the blower motor's fan speed. When you turn a knob to produce more air flow for heat or cool air, the resistor adjusts the electrical resistance to control the power sent to your blower motor, which changes the speed of the blower motor.
【Time to Replace】 As the fan speed is one of the most frequently adjusted settings of the air conditioning system, the blower motor resistor is put under constant stress, which can cause it to eventually fail. A failed blower motor resistor can cause issues with the operation of the entire heating and air conditioning system. If your blower motor only works on certain speeds or is stuck on one speed, you may have a problem with the blower motor resistor.
