Dorman 973-501 HVAC Blower Motor Resistor Kit

Dorman 973-501 HVAC Blower Motor Resistor Kit

Dorman 973-501 is an HVAC blower motor resistor kit that replaces a failed original resistor and includes the matching harness pigtail for a cleaner electrical repair. It is built for vehicles with an overheated or corroded blower resistor connection, helping restore proper blower motor speed control in the HVAC system.

Key Features

• Includes a blower motor resistor and wire harness for the repair
• Blade-style terminals with a female connector and male terminals
• 4-wire harness with a 6-inch harness length
• Single mounting hole and 4 terminal connection layout
• Direct replacement for select Chrysler Aspen and Dodge Durango auxiliary HVAC applications

Detailed Description

This Dorman HVAC blower motor resistor kit, part number 973-501, is made for select vehicles that use an auxiliary HVAC unit and need replacement of a damaged resistor connection. The included harness pigtail addresses heat-related connector damage and corrosion at the original plug, while the resistor restores blower speed operation through the HVAC control circuit. This part cross-references 4P1328 and 5019639AA for the same application. Compatible with 2007-2009 Chrysler Aspen and 2001-2009 Dodge Durango auxiliary HVAC systems, Dorman 973-501 supports a targeted electrical repair when the blower motor only works on certain speeds or stops responding altogether.

What It Helps Fix

• Blower motor speeds that only work intermittently
• No blower operation at one or more fan settings
• Heat-damaged or corroded resistor connector terminals
• Electrical resistance issues in the HVAC blower circuit
• Auxiliary HVAC blower control problems on select Aspen and Durango models

Installation Notes and Tips

Inspect the connector, terminals, and surrounding wiring before installation. If the original plug shows heat damage or corrosion, replace the resistor and harness together to help ensure a stable electrical connection. Confirm vehicle year, make, model, and auxiliary HVAC configuration before ordering. This part is listed for 2007-2009 Chrysler Aspen and 2001-2009 Dodge Durango, with notes indicating fitment for most auxiliary HVAC units.

Quality Assurance

Dorman supplies replacement electrical components for automotive repair applications, and this kit is built as a service replacement for the original blower motor resistor assembly and connector repair.
