Detailed Description

This Universal Air blower resistor is built for vehicles that use a resistor-based HVAC fan circuit to control blower motor speeds. The SW11450C is listed for 1991-1996 Buick Roadmaster, 1991-1995 Chevrolet Caprice, 1995-1996 Chevrolet Impala, and 1991-1992 Oldsmobile Custom Cruiser, making it a direct-fit option for common GM full-size platform applications. If your Chevrolet Caprice, Impala, or Buick Roadmaster has lost one or more fan speeds, SW11450C is the replacement part to check first.

What It Helps Fix

• Blower motor works only on high speed
• One or more HVAC fan speeds do not operate
• Intermittent cabin airflow control
• No response from the blower switch at lower settings
• Resistor-related HVAC fan speed failure

Installation Notes and Tips

Confirm the original resistor connector and mounting style before installation. Inspect the blower motor, wiring connector, and related HVAC controls for heat damage or corrosion, since a failed blower motor can overload the resistor and shorten service life. Verify vehicle year and model match the listed fitment before ordering.

Quality Assurance

Universal Air SW11450C is cataloged as a blower resistor replacement for the listed GM applications and cross-references OE number 52455732 for the 1996 Chevrolet Caprice application.
