• Replaces overheated or corroded OE resistor assemblies
• Blade terminal design with female connector and male terminals
• 8-wire harness layout with 2 connectors and 2 mounting holes
• 6-inch wiring harness length for service replacement use
• Fits manual climate control applications listed below
• Dorman 973-422 service part for Chrysler and Dodge HVAC repair

Detailed Product Description

This blower motor resistor kit is used to restore cabin fan speed operation when the original resistor or connector has failed from heat, corrosion, or terminal damage. The included harness pigtail helps address damaged wiring at the resistor connection point, making it a practical repair for HVAC electrical connector service. Dorman 973-422 is listed for 2001-2007 Chrysler Town & Country, front; 2004-2007 Chrysler Voyager, front; 2001-2007 Dodge Caravan, front; 2001-2007 Dodge Grand Caravan, front; 2005-2008 Chrysler Pacifica; 2001-2003 Chrysler Voyager, front; and 2001-2002 Chrysler Grand Voyager, front, with the noted climate control exclusions.

This part cross-references Standard Ignition RU1055 for the same application.

What It Helps Fix

• Blower motor only working on certain fan speeds
• No cabin airflow from the HVAC blower circuit
• Intermittent fan operation caused by resistor failure
• Heat-damaged or corroded resistor connector terminals
• Electrical resistance issues in manual climate control systems

Installation Notes and Tips

Verify the vehicle uses the listed manual climate control configuration before ordering. Inspect the blower resistor connector, terminals, and nearby wiring for heat damage before installation. Confirm the mounting points and terminal layout match the original part, and repair any damaged wiring in the harness area as needed.

Quality Assurance

Dorman manufactures replacement electrical and HVAC service parts for repair applications where the original component has failed. Part number 973-422 is built as a service replacement for the listed Chrysler and Dodge vehicles and is intended to restore proper blower motor resistor function.
