Blower Motor Regulator
What this part does
The blower motor resistor controls the speed of the interior heating and air conditioning fan by stepping down the electrical current routed to the blower motor. It is mounted directly into the HVAC air duct behind the dashboard, allowing the constant airflow to cool its internal circuitry during operation. When this component fails, the climate control system typically loses its lower fan speed settings and operates only on high, or the fan stops functioning entirely.

Before you order
Confirm the part number printed on your original unit matches exactly. Vehicles equipped with automatic climate control and manual climate control often use different resistor modules that cannot be swapped. It is highly recommended to inspect the blower motor itself before installing this part; a worn blower motor will draw excess electrical current and quickly burn out the replacement resistor.
