Detailed Description

This Dorman HVAC blower motor resistor kit is built for vehicles that use automatic air conditioning controls and need a replacement for a damaged OE resistor assembly. The included harness pigtail addresses heat-related connector damage and corrosion at the original connection point, helping restore proper electrical contact at the blower motor resistor circuit. Part number 973-425 is listed for 2002-2006 Jeep Liberty, 2002-2006 Jeep TJ with Left Hand Drive, 2002-2006 Jeep Wrangler with Left Hand Drive, and 2007 Jeep Liberty with automatic air conditioning controls. This part cross-references 5066552AA and RU352 for the same application.

Common Problems This Part Can Address

• Blower motor only works on certain fan speeds
• No airflow from the HVAC vents at selected settings
• Heat-damaged or corroded resistor connector
• Intermittent blower operation caused by poor electrical contact
• Failed resistor assembly in the HVAC control circuit

Installation Notes and Tips

Verify the vehicle uses automatic 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. Confirm the mounting location and connector style match the original part, especially on Jeep Liberty, Jeep TJ, and Jeep Wrangler applications. Part number 973-425 uses a female connector with male blade terminals and a 5-wire harness layout.

Quality Assurance

Dorman supplies replacement electrical and HVAC components for specific vehicle applications, and this resistor kit is engineered to match the original connection style and fitment requirements for the listed Jeep models.
