Detailed Description

Universal Air Blower Resistor SW9956C is built for HVAC systems that use a resistor to control blower motor speeds. It serves select GM vehicles including Chevrolet Impala, Chevrolet Monte Carlo, Buick Century, Buick Regal, Pontiac Grand Prix, Oldsmobile Intrigue, Oldsmobile Silhouette, Pontiac Montana, Pontiac Trans Sport, and Chevrolet Corvette across the listed model years. This part number SW9956C is a practical replacement when the blower motor works on some speeds but not others, or when the cabin fan output is inconsistent.

Common Symptoms It Can Address

  • Blower motor operates only on high speed
  • One or more fan speeds do not work
  • Cabin airflow is intermittent
  • HVAC fan output is stuck at a single setting
  • Loss of normal blower speed control in manual HVAC systems

Installation Notes

Verify the vehicle uses a manual blower speed control system before ordering. This resistor is not compatible with Automatic Temperature Control systems on the listed Buick, Pontiac, Oldsmobile, and Chevrolet applications where noted. Confirm the connector style and vehicle fitment against the application list for Chevrolet Impala, Chevrolet Monte Carlo, and Pontiac Grand Prix before installation.

Quality Assurance

Universal Air identifies this component as part of its Blower Resistor line for HVAC service applications. Confirm fitment by year, make, model, and HVAC control type before installation.
