General Motors is recalling certain models because fluid may enter into the driver’s master power window switch module, causing corrosion which could cause the switches to cease working.
The models involved include 2006-2007 Buick Rainer, Chevrolet Trailblazer and GMC Envoy vehicles, as well as 2006 GMC Envoy XL and Chevrolet Trailblazer EXT models.
A short in the circuit board of the driver door module may cause the power door locks and power window switches to function intermittently or stop working, according to GM.
“A short may also cause the windows to raise or lower themselves without user input. In addition the short may cause overheating, which could melt the components of the door module, producing odor, smoke or fire,” according to the document GM provided the National Highway Traffic Safety Administrator (NHTSA). “These conditions may occur even with the vehicle parked and the key removed.”
The automaker noted that these models had previously been recalled for the same issue. GM later discovered that the protective coating remedy did not work effectively and issued another recall. This second recall left out these models because of a technical glitch. The automaker said that according to recall labor codes, they had already received the replacement module.
