Dorman 973-407 HVAC Blower Motor Resistor Kit
Dorman 973-407 is an HVAC blower motor resistor kit for select Chevrolet Express and GMC Savana vans. It includes the resistor and a wire harness pigtail to replace an overheated or corroded original equipment connector and restore blower speed control.
Key Features
- HVAC blower motor resistor kit with resistor and harness pigtail
- Direct replacement for damaged OE resistor connections on select vans
- Blade-style terminals with male connector and terminal design
- 6-inch wiring harness length
- 2 mounting holes and 8-wire harness configuration
- Fits front HVAC applications on Chevrolet Express and GMC Savana models
Detailed Description
This Dorman blower motor resistor kit is built for front HVAC systems on 1996-2023 Chevrolet Express 1500, Express 2500, and Express 3500, plus 1996-2023 GMC Savana 1500, Savana 2500, and Savana 3500 applications listed in the fitment data. Part number 973-407 addresses common resistor and connector wear by replacing the resistor and the harness pigtail together, which is important when the original connector has heat damage or corrosion. This part cross-references DR780 and RU1274 for the same application.
What It Helps Fix
- Blower motor speeds that stop working or only operate on certain settings
- Heat-damaged or corroded resistor connectors
- Intermittent HVAC fan operation
- Loss of cabin airflow control from the front HVAC system
- Electrical connection issues at the blower motor resistor
Installation Notes and Tips
Verify the vehicle year, make, model, and front HVAC configuration before installation. Inspect the connector and surrounding wiring for heat damage, corrosion, or brittle terminals, and replace any damaged wiring as needed. The kit uses blade terminals and includes a harness pigtail, so proper terminal seating and secure electrical connections are important for reliable blower operation. Confirm the mounting points match the original resistor location on the vehicle.
Quality Assurance
Dorman supplies this HVAC blower motor resistor kit as a service replacement for select Chevrolet Express and GMC Savana vehicles. The part is engineered to replace an overheated or corroded original equipment resistor assembly with the needed connector repair components for the listed applications.
This part fits 150 vehicles
