POWER SEATS
DESCRIPTION
Individually controlled, electrically powered front
seats are available as factory-installed equipment on
this model. Vehicles with this option can be visually
identified by the two separate power seat switches,
mounted on each of the front seat cushion side
shields (Fig. 1). The power seat system option allows
the front seating positions to be electrically adjustedfor optimum vehicle control and comfort. The power
seat cushion can be adjusted forward, rearward, front
up, front down, rear up, or rear down. The power
seat system for this vehicle includes the following
major components, which are described in further
detail later in this section:
²Power Seat Switches- Two power seat
switches are used per vehicle, one for the driver and
one for the front seat passenger. Refer to the left and
right power seat switch information later in this sec-
tion.
²Power Seat Tracks- Two power seat tracks
are used per vehicle, one for the driver and one for
the front seat passenger seats. Refer to the power
seat track information later in this section.
²Circuit Breaker- An automatic resetting cir-
cuit breaker (# 1) is located in the Junction Block
and is used to protect the power seat system from
current overload.
Hard wired circuitry connects the power seat sys-
tem components to each other through the electrical
system of the vehicle. These hard wired circuits are
integral to several wire harnesses, which are routed
throughout the vehicle and retained by many differ-
ent methods. These circuits may be connected to each
other, to the vehicle electrical system and to the
power seat system components through the use of a
combination of soldered splices, splice block connec-
tors and many different types of wire harness termi-
nal connectors and insulators. Refer to theWiring
section of this manual for more information. The wir-
ing information includes wiring diagrams, proper
wire and connector repair procedures, further details
on wire harness routing and retention, as well as
pin-out and location views for the various wire har-
ness connectors, splices and grounds.

DIAGNOSIS AND TESTING - SEAT TRACK
(1) Remove the power seat switch from the seat
(Refer to 8 - ELECTRICAL/POWER SEATS/DRIVER
SEAT SWITCH - REMOVAL).
(2) Checking the body harness side of the power
seat switch electrical connector (Fig. 3), check Pin 1
for ground and Pin 5 for battery voltage. If either of
these two are not present repair the body harness as
required.
(3) To test the seat motors and verify proper seat
responses, refer to the Seat Motor Test table below.
Using two jumper wires, connect one to a battery
supply and the second to a ground. Connect the other
ends to the seat wire harness connector as described
in the Seat Motor Test table.

LEFT POWER SEAT SWITCH
DESCRIPTION
Vehicles equipped with the power seat option uti-
lize a six-way power seat switch. This six-way power
seat switch features one seat cushion shaped knob,
visible on the outboard seat cushion side shield (Fig.
4).
The switch is secured to the back of the seat cush-
ion side shield with two screws. However, the control
knob must be removed before the seat switch can be
removed from the side shield.

POWER WINDOWS
DESCRIPTION
The power window system allows each of the door
windows to be raised and lowered electrically by
actuating a switch on the center console. A master
switch on the front of the center console allows the
driver to raise or lower each of the passenger door
windows and to lock out the individual switches on
the rear of the center console from operation. The
power window system receives battery feed through
fuse 13 in the Power Distribution Center (PDC), only
when the ignition switch is in the RUN or ACCES-
SORY position.
OPERATION
WINDOW SWITCH
The power window switches control the battery
and ground feeds to the power window motors. Both
of the rear door power window switches receive their
battery and ground feeds through the circuitry of the
front window switch. When the power window lock-
out switch is in the Lock position, the battery feed
for the rear door window switches is interrupted.
WINDOW MOTOR
Front door window lift 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 ter-
minals 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.
DIAGNOSIS AND TESTING - POWER
WINDOWS
WIRING VOLTAGE TEST
The following wiring test determines whether or
not voltage is continuous through the body harness
to the front switch.
(1) Remove the power window switch and bezel
(Refer to 8 - ELECTRICAL/POWER WINDOWS/
POWER WINDOW SWITCH - REMOVAL).
(2) Disconnect wire connector from back of power
window switch.
(3) Switch ignition to the ON position.
(4) Connect the clip end of a 12 volt test light to
Pin 14 of the window switch harness connector.
Touch the test light probe to Pin 10.
²If the test light illuminates, the wiring circuit
between the battery and switch is OK.
²If the lamp does not illuminate, first check fuse
13 in the Power Distribution Center (PDC). If fuse 13
is OK, then check for a broken wire.
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.
POWER WINDOW MOTOR TEST
If the power window motor is receiving proper cur-
rent and ground and does not operate, proceed with
motor test. Refer to the appropriate wiring informa-
tion. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
details of wire harness routing and retention, connec-
tor pin-out information and location views for the
various wire harness connectors, splices and grounds.
(1) Remove front door trim panel as necessary to
gain access to power window motor wire connector
KJPOWER WINDOWS 8N - 21

(Refer to 23 - BODY/DOOR - FRONT/TRIM PANEL -
REMOVAL).
(2) Disconnect power window motor wire connector
from door harness.
(3) Using two jumper wires, connect one to a bat-
tery (+) source and the other to a good ground (-).
(4) Connect the Negative (-) jumper probe to one of
the motor connector terminals.
(5) Momentarily touch the Positive (+) jumper
probe to the other motor connector terminal.
When positive probe is connected the motor should
rotate in one direction to either move window up or
down. If window is all the way up or down the motor
will grunt and the inner door panel will flex when
actuated in that one direction.
(6) Reverse jumper probes at the motor connector
terminals and window should now move in opposite
direction. If window does not move or grunt, replace
the motor.
If window moved completely up or down, reverse
the jumper probes and cycle window to the opposite
position to verify full operation.
If motor grunts and does not move, verify that reg-
ulator is not binding.
WINDOW MOTOR
REMOVAL
The window motor is incorporated into the window
regulator assembly. If the window motor requires
replacement, the window regulator must be replaced.
(Refer to 23 - BODY/DOOR - FRONT/WINDOW
REGULATOR - REMOVAL) or (Refer to 23 - BODY/
DOORS - REAR/WINDOW REGULATOR - REMOV-
AL).
WINDOW SWITCH
DIAGNOSIS AND TESTING - WINDOW SWITCH
(1) Remove the switch to be tested (Refer to 8 -

DOW SWITCH - REMOVAL).
(2) Using an ohmmeter, Test front switch for con-
tinuity (Fig. 1).

The power window master switch has a Auto-Down
feature on both front windows. The switch is
equipped with two detent positions when actuating
the power window OPEN. The first detent position
allows the window to roll down and stop when the
switch is released. The second detent position actu-
ates an integral express roll down relay that rolls the
window down after the switch is released. When the
express down circuit senses stall current (window
has reached end of down travel), the switch will turn
current off to the motor. The AUTO feature can be
cancelled by actuating the switch UP or DOWN while
window is in motion. If the electronic circuit in the
switch fails to detect a stall current, the auto down
circuit will time out within 9 to 14 seconds.
