A heater blower resistor is a element of a automobile’s heating and air flow system that regulates the velocity of the blower motor. It’s usually situated within the passenger compartment, behind the dashboard. When the heater or air-con is turned on, the resistor reduces the voltage to the blower motor, permitting it to function at a decrease velocity.
Heater blower resistors can fail over time, inflicting the blower motor to function at a better velocity than regular. This could result in elevated noise and put on on the blower motor, and may also cut back the effectivity of the heating and cooling system.
