Dorman 973-536 HVAC Blower Motor Resistor Kit

Dorman 973-536 HVAC Blower Motor Resistor Kit

This Dorman HVAC blower motor resistor kit restores blower speed control on select Buick, Pontiac, and Oldsmobile vehicles. It includes the resistor and a wire harness pigtail to replace an overheated or corroded original connector, helping address common HVAC electrical failures.

• Direct replacement blower motor resistor kit for select HVAC systems
• Includes a replacement resistor and harness pigtail
• Blade-style terminals with a male connector and male terminals
• 9-wire harness with a 6-inch wiring harness length
• 3 mounting holes and 9 terminals for the specified application
• Compatible With 2002-2005 Buick Rendezvous, 2001-2005 Pontiac Aztek, 2001-2005 Pontiac Montana, and 2001-2004 Oldsmobile Silhouette

Detailed Product Information

Dorman 973-536 is built for vehicles where the original blower motor resistor has been damaged by heat or where the connector has become corroded. The kit addresses the electrical connection at the HVAC blower circuit by replacing both the resistor and the harness pigtail, which is important when the original plug shows signs of overheating, melting, or terminal wear. This part cross-references Monroe Shocks & Struts (e.g., DR759, RU909) for the same application.

Use Dorman 973-536 when servicing HVAC blower speed issues on a 2002-2005 Buick Rendezvous, 2001-2005 Pontiac Aztek, 2001-2005 Pontiac Montana, or 2001-2004 Oldsmobile Silhouette. The part number 973-536 is also a useful reference when verifying the correct resistor kit for these vehicles.

Common Problems This Part Can Address

• Blower motor works only on certain fan speeds
• No cabin airflow from the HVAC blower on some settings
• Heat-damaged or corroded resistor connector
• Intermittent HVAC fan operation caused by poor electrical contact
• Failed blower resistor circuit in the HVAC control system

Installation Notes and Tips

Inspect the connector, terminals, and surrounding wiring before installation. If the original harness shows heat damage or corrosion, replace the affected connection rather than reusing compromised terminals. Confirm the vehicle application and connector style before installation, and verify proper blower operation after the repair.

Quality Assurance

Dorman supplies this resistor kit as a replacement solution for the specified HVAC electrical repair. The included resistor and harness pigtail are intended to restore the connection point commonly affected by heat and corrosion in the blower motor circuit.
