This regulator replaces the mechanical lift mechanism inside the door that moves the window glass up and down. It is compatible with the power window system and integrates with the existing motor, switch, and wiring. Installation requires removal of the interior door panel and use of a rivet gun to secure the assembly. Disconnect the vehicle battery before beginning installation to prevent accidental airbag deployment.
