Dorman HVAC Blower Motor Resistor Kit 973-572

Dorman 973-572 is an HVAC blower motor resistor kit that replaces an overheated or corroded original resistor and restores blower speed control on select Chrysler and Dodge vehicles. It includes the resistor and harness pigtail needed for a proper electrical repair.

Key Features

• Direct replacement HVAC blower motor resistor kit for select manual climate control systems
• Includes a replacement resistor and wire harness pigtail for connector repair
• Blade terminal design with 4-wire harness configuration
• Gasket or seal included for the installation interface
• 11-inch wiring harness length
• Fits 2008-2010 Chrysler Town & Country, main unit, with manual air conditioning controls
• Fits 2008-2010 Dodge Grand Caravan, main unit, with manual air conditioning controls
• Fits 2008 Chrysler Voyager, front, with manual climate control

Detailed Description

This Dorman HVAC blower motor resistor kit, part number 973-572, is built for vehicles that use manual climate or air conditioning controls and need a replacement for a damaged resistor circuit. It addresses heat-related failure and connector corrosion by pairing the resistor with a matching harness pigtail, helping restore consistent blower motor speed operation in Chrysler Town & Country, Dodge Grand Caravan, and Chrysler Voyager applications.

This part cross-references 68029723AA and RU642 for the same application.

Common Problems It Can Solve

• Blower motor works on only one speed or loses multiple fan speeds
• Intermittent HVAC fan operation caused by a failing resistor
• Connector damage from heat, corrosion, or melted terminals
• No airflow from the cabin vents when the blower control is turned on
• Erratic blower speed response from a worn electrical connection

Installation Notes and Tips

Verify the vehicle uses manual climate or manual air conditioning controls before ordering. Inspect the connector and surrounding wiring for heat damage before installation, and replace any damaged terminals or wiring as needed. The included harness pigtail is intended to repair the electrical connection at the resistor location, and the gasket or seal helps support a proper fit at the mounting point.

Quality Assurance

Dorman manufactures replacement electrical and HVAC components for repair applications, and this kit is engineered to replace the original resistor assembly on the listed vehicles. Part number 973-572 is built to address common resistor and connector failure points in the HVAC blower circuit.
