Dorman 973-484 HVAC Blower Motor Resistor Kit

Dorman 973-484 HVAC Blower Motor Resistor Kit

Dorman 973-484 is an HVAC blower motor resistor kit that replaces an overheated or corroded original resistor and restores blower speed control on select Ford and Lincoln vehicles. It includes the resistor and harness pigtail needed for a direct electrical repair on the affected circuit.

Key Features

• HVAC blower motor resistor kit for blower speed control repair
• Includes a resistor and harness pigtail for the electrical connection
• 15.5-inch wiring harness length
• 4-wire, 4-terminal design with female connector and male blade terminals
• 2 mounting holes for OE-style installation
• Fits 2007-2015 Ford Edge and 2007-2015 Lincoln MKX applications listed below

Application Details

This Dorman blower motor resistor kit is built for select Ford Edge and Lincoln MKX models, including 2007-2010 Ford Edge and Lincoln MKX with automatic air conditioning controls, plus 2011-2015 Ford Edge and Lincoln MKX. Part number 973-484 is a practical replacement when the original resistor has heat damage, corrosion, or connector wear that interrupts blower operation. This part cross-references Four Seasons 20622 for the same application.

What It Helps Fix

• Blower motor only working on certain speeds
• No cabin airflow from the HVAC blower
• Intermittent fan operation caused by a damaged resistor circuit
• Heat-related connector or terminal damage at the resistor plug
• Corrosion at the original HVAC electrical connection

Installation Notes

Inspect the blower motor connector, resistor cavity, and surrounding wiring before installation. If the original connector shows heat damage or corrosion, replace the damaged section and verify terminal fitment before reconnecting. Confirm the vehicle’s HVAC control configuration, especially on 2007-2010 Ford Edge and Lincoln MKX models with automatic air conditioning controls. Use proper electrical repair practices and verify blower speeds after installation.

Quality Assurance

Dorman replacement parts are engineered to address common OE failure points in vehicle electrical systems. Part number 973-484 is built as a service replacement for the listed Ford Edge and Lincoln MKX applications.
