A heater blower resistor is a element of a automobile’s heating and air flow system that regulates the pace of the blower motor. It’s sometimes 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 pace.
Heater blower resistors can fail over time, inflicting the blower motor to function at a better pace than regular. This may result in elevated noise and put on on the blower motor, and may cut back the effectivity of the heating and cooling system.
