Dorman 973-515 HVAC Blower Motor Resistor Kit

Dorman 973-515 is an HVAC blower motor resistor kit that replaces an overheated or corroded original resistor and restores blower speed control on select vehicles. It includes the resistor and harness pigtail needed for a proper electrical repair in the HVAC system.

  • HVAC blower motor resistor kit for blower speed control repair
  • Includes a replacement resistor and wire harness pigtail
  • 4-wire, 4-terminal design with blade terminals
  • Female connector with male terminals for the repair connection
  • 6-inch wiring harness length for service replacement use
  • 2 mounting holes; mounting hardware not included

Vehicle Fitment

  • Fits 2001-2005 Pontiac Montana, N/A — HVAC Blower Motor Resistor Kit - Fits most auxiliary HVAC units
  • Fits 2001-2004 Oldsmobile Silhouette, N/A — HVAC Blower Motor Resistor Kit - Fits most auxiliary HVAC units

This Dorman blower motor resistor kit is built for select auxiliary HVAC units in the Pontiac Montana and Oldsmobile Silhouette. Part number 973-515 addresses common electrical failure points at the resistor connection by replacing the damaged resistor and the harness pigtail together, helping restore consistent fan-speed operation. This part cross-references Dorman OE Solutions (e.g., 3A1285, RU375) for the same application.

Common Repair Symptoms

  • Blower motor works on only certain fan speeds
  • No airflow from the HVAC vents at some settings
  • Intermittent blower operation caused by heat-damaged terminals
  • Corrosion at the resistor connector
  • Electrical resistance issues in the auxiliary HVAC blower circuit

Installation Notes

Inspect the connector, terminals, and surrounding wiring before installation. Replace any heat-damaged or corroded wiring at the same time, and verify the resistor mounting points match the vehicle’s HVAC housing. Confirm the connector style, terminal count, and harness length before final assembly. Part number 973-515 uses a 1-connector, 4-wire layout with blade terminals and a female connector interface.

Quality Assurance

Dorman replacement electrical components are engineered to address common OE failure points in service applications. This kit is intended as a direct repair solution for the listed Pontiac Montana and Oldsmobile Silhouette fitments.
