Installation Notes and Tips

Verify the rear left door application before ordering and compare the original regulator to confirm fitment. This part is for power window systems and does not include the motor, so reuse or replace the motor as needed based on the vehicle’s condition. Because mounting hardware is not included, inspect existing fasteners and related door components before installation. For best results, check the window tracks, guides, and glass alignment during service.
