Detailed Product Description

The Dorman 973-515 blower motor resistor kit is engineered to restore proper blower motor function in HVAC systems of Oldsmobile Montana and Pontiac Silhouette models. The included wiring harness, measuring 6 inches in length, provides a direct and secure connection with its female connector and blade-type terminals. The resistor itself is designed to regulate the blower motor speed by controlling electrical current flow, ensuring consistent airflow through the vehicle’s heating and cooling system. With 2 mounting holes, the resistor can be firmly attached to the HVAC housing, although mounting hardware is not included and should be sourced separately.

Common HVAC Issues Addressed by This Resistor Kit

  • Blower motor only works on certain speed settings or not at all
  • Intermittent blower motor operation or inconsistent airflow
  • Overheating or burning smell from the HVAC system
  • Complete loss of blower motor function in Oldsmobile Montana or Pontiac Silhouette
  • Electrical connection failures due to worn or damaged wiring harness

Installation Notes and Tips

  • Ensure vehicle ignition is off and battery disconnected before installation
  • Verify compatibility with Oldsmobile Montana or Pontiac Silhouette models prior to purchase
  • Use appropriate tools to remove the old resistor and wiring harness carefully
  • Secure the resistor using the 2 mounting holes; mounting hardware is not included
