Detailed Description

This blower motor resistor is used to control blower motor speed in the HVAC system by regulating electrical current to the fan circuit. When the original resistor burns out, the result is often loss of one or more fan speeds, inconsistent airflow, or a blower that only works on certain settings. Dorman 973-398 is engineered as a direct replacement for vehicles equipped with dual zone automatic temperature control, including Ford Expedition, Lincoln Navigator, Ford F-150, and Ford Mustang applications listed in the fitment data. If you are searching for a blower motor resistor for a 2017-2019 Ford Explorer, 2009-2014 Ford F-150, or 2009-2017 Ford Expedition, this part number is a direct match for the specified configurations.

What It Helps Fix

Blower motor only works on certain speed settings
No cabin airflow from the HVAC vents
Intermittent fan operation
Burnt or heat-damaged resistor failure
Loss of proper heating and cooling control

Installation Notes

Verify the vehicle uses dual zone automatic temperature control before ordering. Match the connector shape, terminal count, and mounting points to the original part before installation. This resistor uses a rectangular connector, 4 terminals, and 2 bolt holes, and it does not include a wiring harness or mounting hardware. Follow the included instructions and inspect the blower motor circuit for heat damage or connector wear before installing the new resistor.

Quality Assurance

Dorman supplies direct replacement HVAC components designed to match original equipment function on the listed applications. Part number 973-398 is intended for the fitments shown and is built to restore normal blower motor speed control in supported Ford, Lincoln, and Mercury vehicles.

This part fits 111 vehicles

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
