JUNE 2013 - General Motors (GM) is recalling certain model year 2006 Chevrolet Trailblazer EXT and GMC Envoy XL and 2006-2007 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, SAAB 9-7x, and Isuzu Ascender vehicles. Fluid may enter the driver's door module, causing corrosion that could result in a short in the circuit board. Chevrolet markets award-winning automobiles, including the Trailblazer, and they are often found on the American highway. The quality manufacture and high value that come with a Chevrolet Trailblazer are good reasons for always acquiring OEM and aftermarket parts of equal value; high-quality parts don't have to break the bank.
