Dorman 973-510 HVAC Blower Motor Resistor Kit

Dorman HVAC Blower Motor Resistor Kit

Dorman 973-510 is an HVAC blower motor resistor kit that replaces a failed original resistor and the related harness pigtail on select vehicles. It is built for repairs where heat damage, corrosion, or connector wear has affected blower motor speed control in the cabin HVAC system.

Compatible with select 2006-2010 Hummer H3, 2009-2010 Hummer H3T, 2007-2010 Saturn Sky, 2006-2009 Pontiac Solstice, 2006 Chevrolet Equinox, and 2006 Pontiac Torrent applications.

• Direct replacement blower motor resistor kit for HVAC fan speed control repairs
• Includes a replacement wire harness pigtail for damaged or overheated connector repair
• Female connector with male blade terminals for the specified application
• 5-wire design with 2 mounting holes and a 6-inch wiring harness length
• Built for vehicles where the original resistor or connector has corroded or heat-damaged terminals

Detailed Product Information

This Dorman blower motor resistor kit, part number 973-510, addresses common HVAC electrical failures by replacing the resistor and the harness connection at the same time. It is a practical repair for blower systems that lose one or more fan speeds, operate intermittently, or stop responding because the original resistor assembly has overheated. This part cross-references Standard Ignition RU1060 for the same application.

Use 973-510 when servicing blower motor resistor circuits on Hummer H3 and H3T, Saturn Sky, Pontiac Solstice, Chevrolet Equinox, and Pontiac Torrent models listed in the fitment data. The kit is designed around the original connector style and terminal layout to support a cleaner electrical repair at the HVAC housing.

Common Repair Symptoms

• Blower motor only works on certain speed settings
• HVAC fan stops working after connector heat damage
• Corroded or burned resistor terminals
• Intermittent cabin airflow from the blower motor circuit
• Failed resistor causing loss of low or medium fan speeds

Installation Notes

Inspect the blower motor connector, resistor mounting area, and surrounding wiring before installation. Replace any heat-damaged terminals or melted insulation in the circuit, and verify the harness routing matches the original layout. This part uses blade terminals, a female connector, and two mounting holes; confirm the vehicle’s connector style and mounting pattern before service.

Quality Assurance

Dorman manufactures replacement electrical and HVAC service parts for OE-style repairs. Part number 973-510 is intended to restore proper blower motor resistor function on the listed applications using the included resistor and harness pigtail.
