Dorman 973-057 HVAC Blower Motor Resistor Kit

This Dorman HVAC blower motor resistor kit restores blower speed control on select Ford, Lincoln, and Mercury vehicles with Dual Zone Automatic Temperature Control. It includes the resistor and harness pigtail needed to replace an overheated or corroded original connector on Fusion, MKZ, and Milan applications.

  • Direct replacement HVAC blower motor resistor kit for select automatic climate control systems
  • Includes a replacement resistor and wire harness pigtail
  • Female connector with male blade terminals for the specified application
  • 5-wire harness layout with an 11-inch harness length
  • Single mounting point design for the original location
  • Part number 973-057 for service matching and catalog lookup

Detailed Product Information

Dorman 973-057 is built for vehicles that use a blower motor resistor assembly with a separate harness repair lead. It is a practical replacement for heat-damaged or corroded electrical connections that can interrupt blower motor operation in the 2010-2012 Ford Fusion, 2010-2012 Lincoln MKZ, and 2010-2011 Mercury Milan equipped with Dual Zone Automatic Temperature Control. This part cross-references 6E5Z19E624AA and RU797 for the same application.

The kit is configured with a female connector, male blade terminals, and five terminals to match the original electrical interface. The included harness pigtail supports repair of the connector side when the factory plug has been affected by heat or corrosion. Use part number 973-057 when searching for a blower motor resistor kit for these specific Ford, Lincoln, and Mercury climate control systems.

What This Part Helps Resolve

  • Blower motor speeds that stop working or only operate on certain settings
  • Intermittent HVAC fan operation caused by a damaged resistor circuit
  • Heat-related connector damage at the resistor harness
  • Corrosion at the electrical connector that interrupts blower control
  • Loss of cabin airflow control in Dual Zone Automatic Temperature Control systems

Installation Notes and Tips

Install this resistor kit in the original resistor location and verify the connector style, terminal count, and harness routing before installation. Because the original failure may involve heat damage at the connector, inspect the mating plug and surrounding wiring for discoloration, melting, or corrosion before reconnecting. Confirm vehicle application by year, make, model, and HVAC configuration before ordering.

Quality Assurance

Dorman replacement electrical components are built for service use on the listed applications and are cataloged for direct vehicle matching. Verify fitment for 2010-2012 Ford Fusion, 2010-2012 Lincoln MKZ, and 2010-2011 Mercury Milan with Dual Zone Automatic Temperature Control before installation. Part number 973-057 is also referenced in service catalogs for these applications.
