Door Lock Striker

The front and the rear door lock strikers each consist of a striker with two screws threaded into a floating cage plate in the B-pillars and the C-pillars. The door is secured in the closed position when the door lock fork snaps over and engages the striker.

Power Door Locks

The power door locks use a solenoid that is contained in each door lock assembly. The door locks are activated by the actuator on the inside door handle or by the lock cylinder on the driver’s side door only. When the driver’s side door is locked or unlocked by the actuator or the lock cylinder, all doors are locked or unlocked accordingly.

Power Windows

The power windows are controlled by electrical switches on the door panels and are operated by a motor at each window regulator. Each door has a switch to control its window, and the driver’s side door has four switches to control all door windows on the vehicle. The windows are lowered by pressing the switch and raised by pulling up on the switch. The window will stop movement when the switch is released or when the window is completely open or closed.

The driver’s side window opens automatically. By pressing and releasing the switch, the driver’s side window will lower and will stop only when the switch is activated again, or when the window is completely open.

The driver’s side door control also contains a window lock button that will prevent the operation of the front passenger door or the rear door windows when pressed.
