2006 Chevrolet Trailblazer recalls (5)
- VISIBILITY:POWER WINDOW DEVICES AND CONTROLS
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.
Risk: 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.
Remedy: GM will notify owners, and dealers will install a new driver's door switch module, free of charge. The recall began on November 2, 2015. Owners may contact Buick customer service at 1-800-521-7300, Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is 15700.
- EXTERIOR LIGHTING:HEADLIGHTS
General Motors LLC (GM) is recalling certain model year 2007 Pontiac Grand Prix, 2006-2009 Buick LaCrosse, 2006-2007 Buick Rainier, Chevrolet Trailblazer, GMC Envoy, 2006 Chevrolet Trailblazer EXT, GMC Envoy XL, 2006-2008 Isuzu Ascender, and Saab 9-7x vehicles. In the affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.
Risk: Headlamps that do not illuminate reduce the driver's ability to see the roadway and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will replace the HDM, free of charge. The recall began on May 17, 2016. Owners may contact Buick customer service at 1-800-521-7300 or Pontiac customer service at 1-800-762-2737. GM's number for this recall is 14291.

A short may cause the power door lock and power window switches to function intermittently or become inoperative.

Risk: A short in the circuit board could lead to a fire, increasing the risk of personal injury. A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made.
Remedy: GM will notify owners, and dealers will inspect the part number on the door module, and install a new door module if necessary, free of charge.

The headlamps have quit working when driving at night but will come back on later. This has happened several times. I found GM recall number 14291 that is supposed to include 2006 Chevy Trailblazers and pertains to this problem. The local dealership told us that our vehicle has a vin number that is not covered. It would seem that all model 2006 Chevy Trailblazers would use the same HDM modules in them when they were built. Is ours covered?
