This is a window regulator with the motor for the front, left window on many different GM vehicles from 1999-2014. 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 2002-2008 Cadillac Escalade, 2002-2013 Chevy Avalanche, 1999-2014 Chevy Silverado, 2000-2014 Chevy Suburban, 2000-2014 Chevy Tahoe, 1999-2014 GMC Sierra, and 2000-2014 GMC Yukon trucks. 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.
