This is a window regulator with the motor for the front, left window on many different GM vehicles from 2002-2009. This is a used regulator with the motor in good working condition with normal wear and tear. This is guaranteed to work perfectly. This is for 2004-2007 Buick Rainier, 2002-2009 Chevrolet Trailblazer, 2002-2009 GMC Envoy, and 2002-2004 Oldsmobile Bravada vehicles. This is a factory OEM, genuine GM regulator, not a cheap aftermarket part.

A failed window regulator can cause your power window to get stuck, make a grinding noise, or make your window appear to be off track. Replace your regulator and make your window work like new again.
