Keystone AC1350123 Front Left Power Window Regulator Without Motor

The Keystone AC1350123 is an OEM-replacement front left (driver side) power window regulator designed for the 2019–2023 Acura RDX. This regulator is sold without the motor, allowing technicians to reuse the original window motor or source it separately — an ideal solution for collision repair and door restoration work where only the regulator mechanism has failed.

The window regulator is the mechanical assembly mounted inside the door that raises and lowers the window glass in response to motor input. Common signs of a failed regulator include a window that won't move, moves slowly or unevenly, makes clicking or grinding noises, or drops inside the door panel.

Key Features:

• Direct OEM-style replacement for the front left door window regulator
• Power-operated design; motor not included
• Engineered to OEM specifications for precise fit and reliable operation
• Designed for installation behind the interior door trim panel
• Compatible with the cable-type regulator design used on the 2019–2023 Acura RDX

Part Numbers & Cross-References:

• Keystone Part Number: AC1350123
• OEM Reference: 72250-TJB-A01 / 72250TJBA01

Installation requires removal of the interior door trim panel and vapor barrier to access the regulator mount points within the door shell. The existing power window motor is transferred to this replacement regulator during reassembly.
