DOOR LOCK STRIKER ADJUSTMENT
(Front Door Shown, Rear Door Similar)
The door lock striker consists of a striker with two screws
that are threaded into a tapped, floating cage plate located
in the appropriate body pillar. This floating cage plate al-
lows the striker to be easily adjusted in and out or up and
down.
The door is secured in the closed position when the door
lock fork snaps over and engages the striker.
Notice : The door lock striker is an important attaching
part that can affect the performance of vital components
and systems. It can cause major repair expenses. If re-
placement becomes necessary, the door lock striker must
be replaced by one with the same part number or with an
equivalent. Do not use a replacement part of lesser quality
or of a substitute design. The specified torque values must
be used during reassembly to ensure the proper retention
of the part.
Up/Down or In/Out Adjustment
An adjustment of the striker in the up and down or in and
out directions may be necessary for a number of reasons:
S Vehicle frame damage as the result of a collision.
S Installation of new door weatherstripping.
S Customer complaints of excessive windnoise.
S Difficulty in opening or closing the door.
To adjust the door striker in an up and down or in and out
direction, perform the following procedure:
1. The door must be properly aligned.
2. Loosen the striker screws.
3. The floating cage plate can be moved slightly using
the ends of the striker screws. Move the floating
cage plate to the desired position.
4. If proper adjustment requires that the floating cage
plate be moved more than is possible, use an elec-
tric hand drill and a 3/8–inch rotary file bit with a flat
head to enlarge the body opening in the direction
required.
Notice : It is important to use a flat–tipped drill bit to pre-
vent damage to the tapped floating cage plate. The striker
screws and the tapped floating cage plate are important
attaching parts that could affect the performance of vital
components and systems.
5. Tighten the door lock striker screws to the correct
position.
Tighten
Tighten the door lock striker screws to 24 NSm (18 lb–
ft).

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. The rear pas-
sengers will be unable to open the doors from inside of the
vehicle.
To deactivate the locks, 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 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 low-
er 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 passen-
ger door or the rear door windows when pressed.

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.
