Dorman 973-951 HVAC Blower Motor Resistor Kit

Dorman 973-951 is an HVAC blower motor resistor kit that replaces an overheated or corroded original resistor on select Ford, Lincoln, and Mercury vehicles. It includes the resistor and a harness pigtail to restore blower motor speed control in manual HVAC systems.

Key Features

  • HVAC blower motor resistor kit for manual climate control applications
  • Includes a replacement resistor and wiring harness pigtail
  • 11-inch wiring harness length
  • 4-wire harness with blade terminals
  • Female connector with male terminals
  • Gasket or seal included for the installation area
  • 2 mounting holes and 1 connector interface

Detailed Description

This Dorman blower motor resistor kit is built for vehicles that use a manual HVAC control setup and need a direct replacement for a damaged resistor circuit. The harness pigtail helps address heat-related connector damage and corrosion at the original connection point, which is common when blower motor resistor failure affects fan speed operation. The Dorman 973-951 is a practical replacement for applications such as the Ford Explorer, Ford Expedition, Lincoln Navigator, Mercury Mountaineer, and Lincoln Aviator with the listed HVAC configurations.

This part cross-references Four Seasons 20301 for the same application.

What It Helps Fix

  • Blower motor speeds that stop working or only operate on certain settings
  • Heat-damaged resistor connectors
  • Corroded HVAC electrical terminals
  • Intermittent cabin fan operation
  • Loss of rear auxiliary HVAC blower control on listed applications

Installation Notes and Tips

  • Verify the vehicle uses manual A/C or manual climate control before ordering.
  • Match the connector style, terminal count, and harness layout to the original part.
  • Inspect the blower motor connector and surrounding wiring for heat damage before installation.
  • Use the included butt connectors to complete the harness repair as needed.
  • Confirm fitment for the exact model year and HVAC configuration, especially on 2007 Explorer, Explorer Sport Trac, and Mountaineer applications with cutoff-date notes.
