This is a window regulator with the motor for the rear, left window on many different GM vehicles from 2007-2014. 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 2007-2014 Cadillac Escalade, 2007-2013 Chevy Avalanche, 2007-2014 Chevy Silverado, 2007-2014 Chevy Suburban, 2007-2014 GMC Sierra, and 2007-2014 GMC Yukon trucks. This is for Crew Cab trucks with 4 doors. 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.
