Installation Notes

Verify the front left door application, power window setup, and connector or mounting style before installation. Transfer or source any required mounting hardware separately, since hardware is not included. Because the motor is not included, confirm whether the existing motor is reusable or whether the full assembly needs to be serviced during repair.

Quality Assurance

This ACI window regulator is a new replacement part built to meet or exceed OEM standards for the listed Lexus applications. Confirm fitment by year, model, and front left position before installation.
