Dorman 973-5091 HVAC Blower Motor Resistor Kit

Dorman 973-5091 is an HVAC blower motor resistor kit that replaces an overheated or corroded original resistor on select vehicles. It includes the resistor and a harness pigtail to restore blower speed control and address common electrical connector damage.

Key Features

• HVAC blower motor resistor kit for blower speed circuit repair
• Includes a replacement resistor and harness pigtail
• 4-wire, 4-terminal design with male blade terminals
• 5.5-inch wiring harness length
• 2 mounting holes for direct replacement-style installation
• Package contents: 1 blower motor resistor kit with harness

Detailed Description

This Dorman HVAC blower motor resistor kit, part number 973-5091, is built for vehicles that have lost one or more blower speeds due to heat damage, corrosion, or connector wear at the resistor circuit. The included harness pigtail helps address damaged factory wiring at the same time as the resistor, which is important when the original connector shows signs of overheating or terminal deterioration. For buyers searching for a blower motor resistor kit for Dorman 973-5091 applications, this part supports a cleaner electrical repair on select HVAC systems. This part cross-references Monroe Shocks & Struts (e.g., 577.55591, 506552C1) for the same application.

What It Helps Fix

• Blower motor works only on certain fan speeds
• No cabin airflow from the HVAC blower on some settings
• Intermittent blower operation caused by heat-damaged resistor circuits
• Corroded or overheated connector terminals at the resistor plug
• Electrical resistance issues that affect HVAC fan control

Installation Notes and Tips

Verify connector style, terminal count, and mounting-hole layout before installation. This kit uses a male connector and male blade terminals, with a 4-wire harness and no gasket or seal included. Confirm the vehicle’s HVAC resistor location and inspect the blower motor connector and surrounding wiring for heat damage before completing the repair. Search terms such as Dorman 973-5091 blower motor resistor kit, HVAC blower resistor with harness, and replacement resistor pigtail for select make/model applications are commonly used by shoppers comparing repair parts.

Quality Assurance

Dorman supplies replacement electrical and HVAC service parts for repair-focused applications, and this kit is built to replace a failed original resistor assembly on select vehicles. Confirm fitment by matching the connector, terminal count, and mounting pattern to the original part before ordering.
