HVAC Blower Motor Resistor Kit for Ford Applications
Dorman 973-414 is an HVAC blower motor resistor kit that replaces an overheated or corroded original resistor and restores blower speed control on select Ford, Lincoln, and Mercury vehicles. It includes the resistor and a harness pigtail for a direct repair on common HVAC electrical connector failures.
Key Features
- HVAC blower motor resistor kit with resistor and wiring harness pigtail
- Blade-style terminals with a female connector and male terminals
- 4-wire, 4-terminal design with 1 connector and 2 mounting holes
- Includes gasket or seal for the repair area
- Direct replacement for select Ford Escape, Ford Expedition, Ford F-150, Ford Mustang, Lincoln Navigator, Mercury Mariner, and Mercury Villager applications
- Dorman 973-414 is built for vehicles where the original resistor or connector has heat damage or corrosion
Detailed Description
This Dorman HVAC blower motor resistor kit is made for vehicles that have lost one or more blower speeds because the original resistor or connector has failed. The included harness pigtail addresses damaged terminals and heat-related connector wear, helping restore proper blower motor operation in the HVAC system. Dorman 973-414 is a practical replacement for common service issues on Ford Escape, Ford Expedition, Ford F-150, Ford Mustang, Lincoln Navigator, Mercury Mariner, and Mercury Villager models.
Cross-reference part numbers include 4L3Z19A706AA and RU382 for the same application.
Common Problems This Part Can Solve
- Blower motor works only on certain fan speeds
- No airflow from the HVAC vents due to resistor failure
- Heat-damaged or corroded resistor connector terminals
- Intermittent blower operation caused by poor electrical contact
- HVAC fan speed control loss in Ford, Lincoln, and Mercury trucks and SUVs
Installation Notes and Tips
Inspect the blower motor connector, resistor cavity, and surrounding wiring before installation. Replace any heat-damaged terminals or melted insulation found at the connector. Confirm the vehicle’s year, make, model, and HVAC configuration before ordering, since fitment varies by application and position. Use the included instructions during installation and verify blower operation after the repair.
Quality Assurance
Dorman supplies this resistor kit as a replacement for failed original equipment components on select vehicles. The kit includes the resistor, wiring harness, and instructions to support a complete electrical repair at the HVAC blower motor circuit.
This part fits 74 vehicles
Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
