Fully functional used master power window switch assembly engineered specifically for 2006 through 2009 Chevrolet Trailblazer models, positioned as the primary left-side driver door control.

Restored to operational condition, this OE window control board manages all four window up and down commands while integrating the standard lockout function that disables passenger window overrides during solo driving. The unit carries the E1 terminal configuration, ensuring exact pin alignment and tactile feedback matches factory specifications for seamless plug-and-door-panel installation.

Direct Fit & Component Layout

This assembly drops directly into the original door cavity without wiring modifications, splice repairs, or adhesive replacements. Before reinstalling, clean the contact pins on your factory harness to prevent intermittent resistance. The control face houses individual toggle switches for the front left, front right, rear left, and rear right windows, alongside a separate master lock override button.

Fits Chevrolet Trailblazer production years 2006, 2007, 2008, and 2009

Installation Procedure

Remove the four Phillips fasteners securing the interior door armrest, release the plastic retention clip behind the handle bezel, and disconnect the multi-pin harness from the rear of the switch housing. Reversing these steps secures the unit in roughly fifteen minutes using standard hand tools. Confirm all four window directions activate smoothly and verify the master lock engagement rating before remounting interior trim panels.
