What's wrong?
The driver door master power window switch module is the control unit inside the driver's door for the power windows. On affected 2006-2007 Rainier, Trailblazer, Trailblazer Ext, Envoy Xl, and Envoy vehicles, that module contains a printed circuit board that routes power when you use the window switches. It also sits where fluid from the door area can reach it.
The problem starts when fluid gets into the driver's door module and corrodes the printed circuit board. Corrosion can create a short between power and ground, which can make the window switches stop working. Some vehicles had the board treated with a protective coating during an earlier recall, but that coating did not sufficiently stop corrosion. The replacement module moves the power trace away from the board edge, reducing the chance that moisture creates a short.
Owners can see the windows raise or lower without anyone touching the switch. The power door locks and power window switches can also work off and on, or stop working, even when the vehicle is parked and the key is removed.
Who's affected?
Spans Rainier, Trailblazer, Trailblazer Ext, Envoy Xl, and Envoy SUVs across the 2006 and 2007 model years, all tied to the same power window controls.
