Product Details

This ACI Window Assembly line part is engineered as a motor and regulator unit for restoring front left window operation. The ACI 88800 is listed for 1999-2002 Mercury Villager and 1999-2002 Nissan Quest front left applications, making it a focused replacement for vehicles with power window failure at the driver-side front door. This part cross-references Continental WL44155 for the same application.

Use ACI 88800 when you need a replacement window motor assembly that matches the original power window function and mounting style. The hardened steel gear supports consistent gear transfer, while the new construction helps restore normal window movement in the Mercury Villager and Nissan Quest.

Professional installation is recommended for accurate alignment and operation after replacement.
