Built for Electrical Switching Performance

Standard Ignition CBS-1477 is engineered as a direct replacement door window switch for the Chevrolet Trailblazer and Chevrolet Trailblazer EXT. The switch uses copper alloy conductors to support strong electrical conductivity with low resistance, and each unit is tested for mechanical and electrical switching performance before release. This part number, CBS-1477, is intended for front left applications with black finish and without heated seats.

This part cross-references Monroe Shocks & Struts (e.g., 901-650R, 10379424) for the same application.

Common Problems This Switch Can Address

• Inoperative driver-side power window control
• Intermittent window switch response
• Broken or worn electrical contacts inside the switch
• Loss of proper switch function at the front left door
• Electrical mismatch from a damaged original unit

Installation Notes and Tips

Verify the vehicle is a 2006-2009 Chevrolet Trailblazer or 2006 Chevrolet Trailblazer EXT with the front left, black-finish, w/o heated seats configuration before installation. Confirm connector style, terminal count, and terminal type against the original switch. Because CBS-1477 may require programming, complete any vehicle-specific setup after the switch is installed.

Quality Assurance

Standard Ignition builds this switch with durable materials and validates both the electrical and mechanical operation of the unit through testing. The design reflects long-term development focused on service-professional requirements and consistent replacement performance.
