Key Features

• HVAC blower motor resistor for manual blower speed control
• Direct fit application for Chevrolet Sonic, Chevrolet Trax, and Chevrolet Spark
• Addresses loss of one or more fan speeds caused by resistor failure
• Part number SW11618C for catalog and fitment lookup
• Universal Air Blower Resistor product line

Detailed Description

The Universal Air Blower Resistor line focuses on replacement HVAC electrical components for cabin air control systems. SW11618C is the blower resistor used in select Chevrolet compact vehicles to regulate blower motor speed through the HVAC control circuit. If your Chevrolet Sonic, Trax, or Spark has inconsistent fan output, this part number SW11618C is the correct replacement to restore normal blower operation.

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

Common Problems This Part Can Solve

• Blower motor works on only one speed
• Fan speeds 1, 2, or 3 do not operate
• Cabin air flow is stuck at high speed
• HVAC fan stops responding at the control switch
• Intermittent blower operation in the dash HVAC system

Installation Notes and Tips

Verify the original resistor connector and HVAC control style before installation. Inspect the blower motor and wiring for heat damage or corrosion, since a failing motor or damaged connector can shorten the life of the replacement resistor. Confirm vehicle application by year and model before ordering: Fits 2012-2020 Chevrolet Sonic, N/A; Fits 2015-2020 Chevrolet Trax, N/A; Fits 2013-2015 Chevrolet Spark, N/A.
