Detailed Product Information

The Universal Air SW11391C blower motor resistor is used in the HVAC control circuit to regulate blower fan speeds in automatic climate control systems. When the resistor fails, the blower may work only on certain speeds or stop responding altogether. This part number SW11391C is listed for 2002 Chevrolet Silverado, Suburban, Tahoe, Sierra, Yukon, and related Cadillac Escalade applications, plus 2000 Chevrolet Tahoe.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Symptoms

• Blower fan works on only one speed
• HVAC fan speeds are intermittent
• Cabin airflow drops out during normal operation
• Automatic A/C blower control no longer responds correctly
• Front HVAC blower circuit shows resistor-related failure

Installation Notes

Verify the vehicle’s HVAC system type before ordering, since fitment varies by automatic A/C and automatic temperature control configurations. Confirm the connector style and mounting location against the original part before installation. For best results, inspect the blower motor and related wiring for heat damage or corrosion when replacing the resistor.

Quality Assurance

Universal Air offers the Blower Resistor line for HVAC repair applications, and SW11391C is cataloged for specific GM truck and SUV fitments to help ensure correct application matching.
