It restores the original switch feel and function while maintaining the factory-style appearance expected in Chevrolet Trailblazer, GMC Envoy, Cadillac Escalade, and related GM platforms. The switch includes a lever and uses a single black connector with four female terminals for a specific-fit installation.

For drivers searching for a 2002-2009 Chevrolet Trailblazer multi-function switch, a 2003-2007 Cadillac Escalade cruise control and wiper switch, or a 2003-2006 GMC Sierra steering column control replacement, this part number 2330856 provides the listed factory functions in one assembly.
