Detailed Description

ACI 380182 is a power window regulator designed for the rear left side of the 1998-2004 Acura RL. It is built as a new replacement part with a hardened steel gear to support consistent window travel and reliable engagement in the door assembly. If you are servicing a rear left Acura RL window that has stopped moving, binds, or drops out of position, this regulator provides the correct fitment for the application.

This part cross-references Acura OE numbers 72250SZ3G01 and 72750SZ3A03 for the same application. ACI 380182 is also referenced by aftermarket number D380182.

What It Helps Fix

  • Rear left window that will not raise or lower
  • Grinding or slipping from a worn regulator gear
  • Window movement that is slow, uneven, or intermittent
  • Window glass that no longer stays aligned in the door
  • Failure caused by regulator wear in the power window system

Installation Notes and Tips

Fits 1998-2004 Acura RL, rear left. Confirm the rear left door application before ordering and compare the original regulator layout to the replacement part. Because the motor is not included, reuse the existing motor only if it tests properly and matches the original assembly. Inspect the window tracks, guides, and fasteners during service to help ensure smooth operation after installation.

Quality Assurance

This ACI window regulator is a new part built to meet or exceed OEM specifications for the listed Acura RL application. The hardened steel gear supports dependable operation in a power window system, and the direct-fit design is intended for proper fit and function in the rear left door.
