Product Details

The Keystone GM1551120 is an OEM-style replacement rear passenger-side (right) power window regulator with integrated motor, designed as a direct-fit replacement for the Cadillac CTS and CTS-V (2003–2007). This assembly restores proper power window operation to the rear right door, addressing common failure symptoms such as slow or erratic window movement, abnormal noise, vibration, or complete loss of function.

Key Features:

  • Direct OEM-replacement fit — engineered to match original mounting points and electrical connections
  • Includes integrated power window motor — complete assembly, no separate motor purchase required
  • Rear passenger side (right hand) application
  • Restores smooth, reliable up/down window operation
  • Constructed to meet OEM structural and functional specifications
  • Designed for straightforward installation within the door panel

Part Numbers & Cross-References:

  • Partslink Number: GM1551120
  • OEM Reference Number: 15277679

This regulator assembly is the correct replacement when the original unit has worn or failed due to mechanical stress, electrical issues, or normal wear over time. Installation requires removal of the rear door panel to access and swap the assembly.

THMOTORSPORTS responded and shipped my purchases of Auxbeam products very quickly. When received, everything looked to be in great shape. They also had the best prices of several vendors that I looked at. I would strongly recommend anyones next purchase to take a good look at THMOTORSPORTS as they definitely delivered on this purchase.
