Dorman 973-509 HVAC Blower Motor Resistor Kit

Dorman 973-509 is an HVAC blower motor resistor kit for vehicles with manual air conditioning controls. It replaces an overheated or corroded original resistor and includes the resistor plus a harness pigtail for a cleaner electrical repair.

  • Direct replacement blower motor resistor kit for manual A/C systems
  • Includes a 6-inch wiring harness with 4-wire, blade-terminal construction
  • Female connector with male terminals for proper electrical interface
  • 2 mounting holes and 1 connector for straightforward installation
  • Built for repair of heat-damaged or corrosion-affected HVAC resistor circuits

Fitment and application details

Compatible with 2004-2012 Chevrolet Malibu, manual air conditioning controls; 2005-2010 Pontiac G6, manual air conditioning controls; and 2007-2009 Saturn Aura, manual air conditioning controls. This part number, 973-509, is also a cross-reference for OE-style replacement needs in the same application.

Use this HVAC blower motor resistor kit when the blower fan only works on certain speeds, stops working on lower settings, or shows signs of heat damage at the connector. It is a practical repair for Chevrolet Malibu, Pontiac G6, and Saturn Aura models that use manual climate control.

What this part helps correct

  • Blower motor speeds that no longer operate normally
  • Intermittent HVAC fan operation caused by a worn resistor circuit
  • Connector damage from overheating at the resistor harness
  • Corrosion at the original electrical connection
  • Loss of cabin airflow on manual air conditioning systems

Installation notes and tips

Inspect the blower motor connector, resistor mounting area, and surrounding wiring before installation. If the original connector shows heat discoloration or corrosion, replace the damaged pigtail during the repair. Confirm the vehicle uses manual air conditioning controls before ordering or installing Dorman 973-509.

Quality assurance

Dorman supplies this resistor kit as a service replacement for the original HVAC electrical connection. The included harness pigtail supports a more complete repair when the factory connector has been damaged by heat or corrosion.
