The master power window switch in your vehicle is the part that controls all your windows. In some 2006-2007 Buick Rainier, Chevrolet Trailblazer, and GMC Envoy models, water can seep into the switch and cause a problem with the electrical circuit.
Risk if Unfixed
If the circuit board shorts due to corrosion, your window switches could stop working, even if you're not driving. In the worst-case scenario, a fire could start, even if the vehicle is parked and unattended.
Free Fix
Your dealer will replace the faulty switch module with a new one, at no cost to you. You'll receive a notification, and it's essential to schedule the repair as soon as possible.

Original — What Happened
General Motors LLC (GM) is recalling certain model year 2006-2007 Buick Rainier, Chevrolet Trailblazer and GMC Envoy vehicles, and 2006 GMC Envoy XL and Chevrolet Trailblazer EXT vehicles. Fluid may enter into the driver's door master power window switch module, causing corrosion that could result in a short in the circuit board, causing window switches to become inoperative. Previously, the affected vehicles may have had their master power window switch module treated with a protective coating, instead of having it replaced.
Original — Risk if Unfixed
The protective coating may not eliminate the risk that the circuit board could short and result in a fire, even while the vehicle is unattended.
