Heater Blower Motor Resistor

Heater Blower Motor Resistor

This component controls the speed of the blower motor. It adjusts the amount of current sent to the motor, allowing you to set fan speed to low, medium, or high. If the resistor fails, the fan might only work on one speed—or not at all. It’s often located near the blower motor and is relatively simple to replace once diagnosed.
