Keystone GM1551103 Rear Right Power Window Regulator Without Motor

The Keystone GM1551103 is an OEM-style replacement rear right (passenger side) power window regulator designed for the Buick Century (1997–2005) and Buick Regal (1997–2004). This regulator-only unit does not include a window motor, making it the ideal solution when your existing motor is still functional but the regulator mechanism itself has failed. It corresponds to OEM part number 10334398-PFM.

The window regulator is the mechanical assembly inside the door that converts motor output into smooth, controlled up-and-down glass movement. When cables fray, plastic guides crack, or the regulator track binds, the window may drop into the door, move erratically, or stop responding altogether — all signs that the regulator needs replacement.

Key Features:

• Direct-fit OEM replacement — engineered to match original equipment specifications for fit and function
• Regulator only (without motor) — retains your factory motor for a cost-effective repair
• Power window configuration — compatible with factory power window systems
• Rear, right (passenger) side position
• Partslink Number: GM1551103
• OEM Cross-Reference: 10334398-PFM
