REMOVAL
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belttensioner, or instrument panel component diagno-
sis or service. Disconnect and isolate the battery
negative (ground) cable, then wait two minutes for
the system capacitor to discharge before perform-
ing further diagnosis or service. This is the only
sure way to disable the supplemental restraint sys-
tem. Failure to take the proper precautions could
result in accidental airbag deployment.
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the cluster bezel from the instrument
panel (Fig. 29). (Refer to 23 - BODY/INSTRUMENT
PANEL/CLUSTER BEZEL - REMOVAL).
(3) From the back of the cluster bezel, squeeze the
two latches on the headlamp leveling switch body
and push the switch out through the face of the bezel
(Fig. 30).

DESCRIPTION
The power operated outside rear view mirrors
allow the driver to adjust both outside mirrors elec-
trically from the driver side front seat position by
operating a switch on the driver side front door trim
panel. The power mirrors receive a non-switched bat-
tery feed through a fuse so that the system will
remain operational, regardless of the ignition switch
position.

POWER WINDOWS
DESCRIPTION
The power window system allows each of the door
windows to be raised and lowered electrically by
actuating a switch on each door panel. A master
switch on the drivers door allows the driver to raise
or lower each door window. The power window sys-
tem operates only when the ignition switch is in the
RUN or ACCESSORY position.
OPERATION
WINDOW SWITCH
The power window switches control the battery
and ground feeds to the power window motors. The
passenger door power window switches receive their
battery and ground feeds through the circuitry of the
drivers window switch.
WINDOW MOTOR
Window motors use permanent type magnets. The
B+ and ground applied at the motor terminal pins
will cause the motor to rotate in one direction.
Reversing current through the motor terminals will
cause the motor to rotate in the opposite direction.
Refer to the appropriate wiring information. The
wiring information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.
WINDOW MOTOR
REMOVAL
The window motor is serviced with the window
regulator.
POWER WINDOW SWITCH
DIAGNOSIS AND TESTING - POWER WINDOW
SWITCH
Test the power window switch continuity. Refer to
the Power Window Switch Continuity chart to deter-
mine if the continuity is correct in the Off, Up and
Down switch positions (Fig. 1).

VEHICLE THEFT SECURITY
DESCRIPTION
A vehicle theft alarm with a battery powered siren
is available as an option and includes interior moni-
toring, anti-tow away protection and rear window
monitoring based on the heater wires. The alarm is
automatically activated when the central locking sys-
tem is operated.
The alarm will sound when any of the following
occur:
²A door is opened
²A door is unlocked from inside the vehicle
²The hood is opened
²The vehicle is raised at the front or rear
²The trailer wire harness is disconnected
²Movements inside the vehicle
²The central locking is unlocked by a key at any
other door than the driver's door
The alarm is functional about 30 seconds after the
vehicle is locked using the RKE transmitter or the
key in the driver's door. Activation is indicated by the
indicator lights flashing three times and the warning
lamp flashing in the switch. If persons or animals
remain in the locked vehicle, the operator should
switch off the interior monitor to avoid a false alarm.
OPERATION
The anti-theft alarm is activated/deactivated by
locking/unlocking the vehicle with the remote trans-
mitter or with the key at the driver's door. The key
must be held in the locking position for more than
two seconds. Activation is indicated by the turn sig-
nal lights flashing once. Unlocking the vehicle at one
of the other doors will trigger an alarm.
The interior monitoring system included in the
anti-theft alarm is based on ultrasonics and triggersan alarm if an object intrudes the interior of the
vehicle or if any movement is detected inside the
vehicle. For proper and effective protection, all win-
dows and the sunroof must be closed.
To switch off the interior monitoring system and /
or the anti-tow away protection, a switch with LED
indicator light is provided in the switch panel. An
alarm button enables the operator to trigger an
alarm manually and to lock all doors if they are
closed. Triggering an alarm makes the horn sound
and the turn signals flash until the alarm is switched
off.
The anti-theft alarm control unit includes a gradi-
ent indicator as anti-tow away protection. The gradi-
ent indicator triggers an audible and visual alarm if
the vehicle is lifted (to tow away or to remove the
wheels). The alarm remains effective even if the bat-
tery is disconnected as the horn is powered by its
own battery. The interior monitoring system should
be switched off if people and/or animals are left in
the vehicle.
DIAGNOSIS AND TESTING - VEHICLE THEFT
SECURITY
Any diagnosis of the Vehicle Theft Security
system should begin with the use of a diagnos-
tic scan tool. Refer to the appropriate diagnos-
tic information.
INTRUSION SENSOR
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Insert the tip of a small flat-bladed screwdriver
into the notch on one edge of the dome lamp/intru-
sion sensor unit housing to depress the retainer clip
