What's wrong?
The driver's door master power window switch module is the switch panel in the driver door. On these 2005-2007 Rainier, 9-7X, Ascender, Trailblazer, Envoy, Envoy Xl, and Trailblazer Ext vehicles, it controls the power windows and power door locks from the driver's seat. It also carries electrical current through a circuit board inside the door.
Fluid can enter that switch module and start corrosion on the circuit board. Corrosion changes the electrical path and creates a short. When that happens, the window and door lock switches can work intermittently or stop working. The same short can overheat the module, melt door-module components, and produce odor, smoke, or a fire.
There is no warning sign before failure. If the switches cut in and out, stop working, or you smell odor or see smoke from the driver door area, treat the switch module as already failing.
Who's affected?
Spans seven SUV nameplates across the 2005-2007 model years, all tied to the same power window devices and controls.

What's the safety risk?
A short in the door module circuit board creates a fire risk and increases the risk of personal injury, even when the vehicle is parked and not in use. Park outside until the dealer remedy is complete. Repair will be free at any franchised Buick dealer once available.
What should I do?
- Check your VIN to confirm your 2005-2007 Buick Rainier, 9-7X, Ascender, Trailblazer, Envoy, Envoy Xl, or Trailblazer Ext is included in this recall.
- Park outside and away from structures until the door-module repair is complete.
- Review any Buick owner letter about parts availability before scheduling the final repair.
- Contact a franchised Buick dealer and reference recall number 14V404 when you ask about the free driver-door module inspection and replacement.
- Watch for odor, smoke, inoperative window switches, or door-lock problems, and stop using the vehicle if those signs appear.
What happens at the repair
At the dealer, a Buick technician inspects the part number on the driver's door master power window switch module. If the vehicle still has the affected module, the technician installs a new door module. Parts and labor are covered under the recall, but the campaign filing says parts were not available when the remedy was announced. The final dealer repair will be free once available. Until then, follow the interim owner letter and contact a Buick dealer if the power window or door lock switches stop working, or if you notice odor or smoke from the door switch area.
