GENERAL DESCRIPTION
AND SYSTEM OPERATION
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.
CHILDPROOF REAR DOOR LOCK
The childproof rear door locks help prevent passengers,
especially children, from opening the rear doors of the ve-
hicle from the inside.
To activate the locks, move the levers of both rear doors
to the lock position. Then, close both doors. Rear passen-
gers will be unable to open the doors from inside of the ve-
hicle.
To deactivate the childproof rear door lock, unlock the door
from the inside of the vehicle and open the door from the
outside. Move the lever to the unlock position. The rear
door will now work normally.
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 cylin-
der on the driver
'
s side door only. When the driver
'
s side
door is locked or unlocked by the actuator or the lock cylin-
der, all the 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 down on the switch and are raised by
pulling up on the switch. The window will stop movement
when the switch is released or when the window is com-
pletely open or closed.
The driver
'
s side window operates automatically. By
pressing and releasing the switch, the driver
'
s side win-
dow will lower. It 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 button that,
when pressed, will prevent the operation of the windows
in the front passenger door or the rear door.

CAUTION : Disconnect the negative battery cable before removing or installing any electrical unit or when a tool
or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable will help
prevent personal injury and damage to the vehicle. The ignition must also be in LOCK unless otherwise noted.
