POWER LOCK SWITCH
DIAGNOSIS AND TESTING - POWER LOCK
SWITCH
The Light-Emitting Diode (LED) illumination lamp
of the power lock switch receives battery current
through a fuse in the Integrated Power Module (IPM)
on a fused ignition switch output (run) circuit. The
power lock switch on the driver side front door trim
panel is integral to the driver door module. (Refer to
8 - ELECTRICAL/POWER LOCKS/DOOR MODULE
- DIAGNOSIS AND TESTING). If the power lock
switch operates, but the LED is inoperative, check
for battery current at the switch with the ignition
switch in the On position. If OK, replace the faulty
switch. Refer to the appropriate wiring information.
(1) Disconnect and isolate the battery negative
cable. Remove the power lock switch from the door
trim panel. Disconnect the door wire harness connec-
tor for the power lock switch from the switch connec-
tor receptacle.
(2) Test the power lock switch resistance. See the
Power Lock Switch Test chart to determine if the
resistance is correct for the switch in each switch
position (Fig. 1). If not OK, replace the faulty power
lock switch as required.

DOOR LOCK MOTOR
DESCRIPTION
The lock mechanisms are actuated by a reversible
electric motor mounted within each door. The power
lock motors are integral to the door latch units.
The power lock motors cannot be adjusted or
repaired and, if faulty or damaged, the door latch
unit must be replaced.
OPERATION
The door lock motors are controlled by the instru-
ment cluster. A positive and negative battery connec-
tion to the two motor terminals will cause the motor
to move in one direction. Reversing the current will
cause the motor to move in the opposite direction.
DIAGNOSIS AND TESTING - DOOR LOCK
MOTOR
The most reliable, efficient, and accurate means to
diagnose the power lock system requires the use of a
DRBIIItscan tool and the proper Diagnostic Proce-
dures manual.
Refer to the appropriate wiring information.

DRIVER DOOR MODULE
DESCRIPTION
A Driver Door Module (DDM) is used on all models
equipped with power locks, power windows, and
power mirrors. The DDM houses the following
switches:
²Power Lock Switch- The DDM includes a
two-way, momentary, resistor multiplexed switch to
control the power lock system.
²Power Mirror Selector Switch- A three-posi-
tion rocker switch in the DDM selects the right or
left power mirror for adjustment, or turns the power
mirror system Off.
²Power Mirror Adjustment Switches- Four
momentary, arrowhead shaped, directional switches
allow the driver to adjust the selected power mirror
in the Up, Down, Right, or Left directions.
²Power Window Lockout Switch- A two-way,
latching, push-button switch in the DDM allows the
vehicle operator to lock out the power window
switches on each passenger door so that the passen-
ger door power windows may be operated only from
the master switches in the DDM.
²Power Window Switches- The DDM houses a
two-way, momentary power window switch for the
driver side front door. This switch also has a second
detent in the Down direction and internal circuitry to
provide an Auto-Down feature for the driver side
front door power window. In addition to the power
window switch for its own door, the DDM houses
individual master switches for each passenger door
power window.
The DDM also incorporates several green Light-
Emitting Diodes (LEDs) that illuminate the power
lock and power window switch paddles, and the
power mirror switch directional buttons to improve
switch visibility in dark ambient lighting conditions.
The DDM cannot be adjusted or repaired and, if
faulty or damaged, the entire DDM unit must be
replaced.
OPERATION
The Driver Door Module (DDM) combines a power
lock switch, a driver power window switch with an
Auto-down feature, master switches for each passen-
ger door power window, a power window lockout
switch, a power mirror selector switch, and four
power mirror adjustment switches in a single unit.
The switches in the DDM can be diagnosed using
conventional diagnostic tools and methods.
Power Lock Switch
The DDM power lock switch circuitry is connected
in series between ground and the driver door switch
mux input of the instrument cluster. Each power lockswitch position (Lock, Unlock, and Neutral) provides
a different resistance value to the instrument cluster
input, which allows the instrument cluster to sense
the switch position. Based upon the power lock
switch input, the instrument cluster controls the bat-
tery and ground feed outputs to the individual power
lock motors to lock or unlock the door latches. The
Light-Emitting Diode (LED) in the DDM power lock
switch is connected to battery current through the
power window circuit breaker in the Integrated
Power Module (IPM) on a fused ignition switch out-
put (run-acc) circuit so that the switch will be illumi-
nated whenever the ignition switch is in the On or
Accessory positions.
Power Window Switches
The DDM power window switch circuitry is con-
nected to battery current through a circuit breaker in
the Integrated Power Module (IPM) on a fused igni-
tion switch output (run-acc) circuit so that the power
windows will operate whenever the ignition switch is
in the On or Accessory positions. Each two-way,
momentary master passenger power window switch
in the DDM provides battery current and ground to
the individual power window switches on each pas-
senger door so that the power window switch controls
the battery current and ground feeds to its respective
power window motor. The DDM switch for the driver
side front door power window is labeled ªAutoº and
includes an auto-down feature. When this switch is
depressed to a second momentary detent position and
released, the driver door power window is automati-
cally operated through an internal circuit and relay
to its fully lowered position. The Auto-down event is
cancelled if the switch paddle is depressed a second
time in either the Up or Down direction. When the
two position window lockout switch in the DDM is
depressed and latched in the lockout position, the
battery current feed to each of the individual passen-
ger power window switches is interrupted so that the
passenger door power windows can only be operated
from the master switches in the DDM. The window
lockout switch also controls the battery current feed
for the LED in each passenger power window switch
so that the switch will not be illuminated when it is
locked out.
Power Mirror Switches
The DDM power mirror switch circuitry is con-
nected to battery current through a fuse in the IPM
on a fused B(+) circuit so that the power mirrors
remain operational regardless of the ignition switch
position. A rocker type selector switch has three posi-
tions, one to select the right mirror, one to select the
left mirror, and a neutral Off position. After the right
or left mirror is selected, one of four directional but-
DRPOWER LOCKS 8N - 5

tons is depressed to move the selected mirror Up,
Down, Right or Left. The DDM power mirror switch
circuitry controls the battery current and ground
feeds to each of the four (two in each mirror head)
power mirror motors. The Light-Emitting Diode
(LED) in the DDM power mirror switch is connected
to battery current through the power window circuit
breaker in the IPM on a fused ignition switch output
(run-acc) circuit so that the switch directional but-
tons will be illuminated whenever the ignition switch
is in the On or Accessory positions.
DIAGNOSIS AND TESTING - DRIVER DOOR
MODULE
The Light-Emitting Diode (LED) illumination
lamps for all of the Driver Door Module (DDM)
power window, power lock, and power mirror
switches receive battery current through the power
window circuit breaker in the Integrated Power Mod-
ule (IPM). If all of the LEDs are inoperative in the
DDM, be certain to diagnose the power window sys-
tem before replacing the switch unit. (Refer to 8 -
ELECTRICAL/POWER WINDOWS - DIAGNOSIS
AND TESTING). If only one LED in the DDM is
inoperative, replace the faulty DDM. If the driver
side front door power window operates in a normal
manner, but the Auto-Down feature is inoperative,
replace the faulty DDM. Refer to the appropriate wir-
ing information.
(1) Disconnect and isolate the battery negative
cable. Remove the DDM from the door trim panel.
Disconnect the door wire harness connectors for the
DDM from the DDM connector receptacles.
(2) Test the DDM switch continuity. See the Driver
Door Module Switch Tests chart to determine if the
continuity is correct for the suspect switches in each
switch position (Fig. 2) and/or (Fig. 3). If not OK,
replace the faulty DDM as required.

POWER MIRRORS
DESCRIPTION
AUTOMATIC DAY/NIGHT MIRROR
The automatic day/night mirror system is able to
automatically change the reflectance of the inside
rear view mirror in order to reduce the glare of head-
lamps approaching the vehicle from the rear. The
automatic day/night rear view mirror receives bat-
tery current through a fuse in the Integrated Power
Module (IPM) only when the ignition switch is in the
On position.
OUTSIDE REAR VIEW MIRROR
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 in the Integrated Power
Module (IPM) so that the system will remain opera-
tional, regardless of the ignition switch position.
OPERATION
AUTOMATIC DAY/NIGHT MIRROR
A switch located on the bottom of the automatic
day/night mirror housing allows the vehicle operator
to select whether the automatic dimming feature is
operational. When the automatic day/night mirror is
turned on, the mirror switch is lighted by an integral
Light-Emitting Diode (LED). The mirror will auto-
matically disable its self-dimming feature whenever
the vehicle is being driven in reverse.
OUTSIDE REAR VIEW MIRROR
The heated mirrors include an electric heating grid
behind the mirror glass in each outside mirror, which
can clear the mirror glass of ice, snow, or fog. (Refer
to 8 - ELECTRICAL/HEATED MIRRORS -
DESCRIPTION) for more information.

AUTOMATIC DAY / NIGHT
MIRROR
DESCRIPTION
The automatic day/night mirror uses a thin layer
of electrochromic material between two pieces of con-
ductive glass to make up the face of the mirror.
When the mirror switch is in the On position, two
photocell sensors are used by the mirror circuitry to
monitor external light levels and adjust the reflec-
tance of the mirror.
OPERATION
The ambient photocell sensor is located on the for-
ward-facing (windshield side) of the rear view mirror
housing, and detects the ambient light levels outside
of the vehicle. The headlamp photocell sensor is
located inside the rear view mirror housing behind
the mirror glass and faces rearward, to detect the
level of the light being received at the rear window
side of the mirror. When the circuitry of the auto-
matic day/night mirror detects that the difference
between the two light levels is too great (the light
level received at the rear of the mirror is much
higher than that at the front of the mirror), it begins
to darken the mirror.
The automatic day/night mirror circuitry also mon-
itors the transmission using an input from the
backup lamp circuit. The mirror circuitry is pro-
grammed to automatically disable its self-dimming
feature whenever it senses that the transmission
backup lamp circuit is energized.
The automatic day/night mirror is a completely
self-contained unit and cannot be repaired. If faulty
or damaged, the entire mirror assembly must be
replaced.
DIAGNOSIS AND TESTING - AUTOMATIC DAY /
NIGHT MIRROR
For complete circuit diagrams, refer to the appro-
priate wiring information.

ambient photocell sensor to keep out any ambient
light.NOTE: The ambient photocell sensor must be cov-
ered completely, so that no light reaches the sen-
sor. Use a finger pressed tightly against the sensor,
or cover the sensor completely with electrical tape.
(7) Shine a light into the rearward facing head-
lamp photocell sensor. The mirror glass should
darken. If OK, go to Step 8. If not OK, replace the
faulty automatic day/night mirror unit.

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 of the passenger door windows and to
lock out the individual switches on the passenger
doors from operation. The power window system
receives battery feed through a fuse in the Integrated
Power Module (IPM) and a circuit breaker located in
the instrument panel wiring harness near the park
brake pedal, 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. When the power window lock-
out switch is in the Lock position, the battery feed
for the passenger door window switches is inter-
rupted.
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.
