magnets. The B+ and ground applied at the motor ter-
minal pins will cause the motor to rotate in one direc-
tion. Reversing current through the motor terminals
will cause the motor to rotate in the opposite direction.

The power window motors ground through the

master switch in the driver door by a black wire
attached to the left cowl panel. Refer to the appropri-
ate

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 connec-
tors, splices and grounds.

The power rear vent windows, if equipped, are

operated by switches mounted in the driver door
switch bezel. A separate switch is used for each win-
dow. Permanent magnet type motors connected to a
crank system are used to open and close the rear
vent windows. A battery positive and negative con-
nection to either of the two motor terminals will
cause the motor to rotate in one direction. Reversing
current through these same two connections will
cause the motor to rotate in the opposite direction.
Refer to the appropriate wiring information. The wir-
ing 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

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 and sound pad as

necessary to gain access to power window motor wire
connector, (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.

WIRING VOLTAGE TEST

The following wiring test determines whether or

not voltage is continuous through the body harness
to switch.

(1) Remove the power window switch and bezel

assembly from the driver door. (Refer to 8 - ELEC-
TRICAL/POWER

WINDOWS/POWER

WINDOW

SWITCH - REMOVAL).

(2) Disconnect wire connector from back of power

window switch.

(3) Switch ignition ON position.
(4) Connect the clip end of a 12 volt test light to

Pin 13 in door harness connector at the window
switch. Touch the test light probe to Pin 9 and then
to Pin 11.

• If the test light illuminates, the wiring circuit

between the battery and switch is OK.

• If the lamp does not illuminate, first check the

25 amp circuit breaker attached to the electrical dis-
tribution wiring bracket. If the circuit breaker is OK,
then check the 40 amp fuse (#28) in the Integrated
Power Module (IPM). If both components are 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.

VENT WINDOW MOTOR

DIAGNOSIS AND TESTING - VENT WINDOW
MOTOR

If the power vent window motor is receiving proper

current and ground and does not operate proceed
with motor test. Refer to the appropriate wiring
information. The wiring information includes wiring
diagrams, proper wire and connector repair proce-
dures, details of wire harness routing and retention,
connector pin-out information and location views for
the various wire harness connectors, splices and
grounds.

(1) Remove D-pillar trim panel necessary to gain

access to power vent window motor wire connector,
(Refer to 23 - BODY/INTERIOR/LEFT D-PILLAR
TRIM PANEL - REMOVAL) or (Refer to 23 - BODY/
INTERIOR/RIGHT

D-PILLAR

TRIM

PANEL

REMOVAL).

(2) Disconnect power vent window motor wire con-

nector from body 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 open or
closed. If window is all the way open or closed the
motor will grunt and the crank system will flex when
actuated in that one direction.

Reverse jumper probes at the motor connector ter-

minals and window should now move in opposite
direction. If window does not move or grunt, replace
the motor.

If window moved completely open or closed, reverse

the jumper probes and cycle window to the opposite
position to verify full operation.

If motor grunts and does not move, verify that

crank system is not binding.

REMOVAL

(1) Disconnect and isolate the battery negative

cable.

(2) Remove D-pillar trim panel. (Refer to 23 -

BODY/INTERIOR/LEFT D-PILLAR TRIM PANEL -
REMOVAL) or (Refer to 23 - BODY/INTERIOR/
RIGHT D-PILLAR TRIM PANEL - REMOVAL).

(3) Disconnect wire connector from power vent

motor.

(4) Using a flat bladed tool, carefully lift the circu-

lar actuator link tab. Remove link from window ball
socket.

(5) Remove bolts holding power vent motor to

D-pillar (Fig. 1).

(6) Remove power vent motor.

The power window master switch has a Auto-Down

feature. The switch is equipped with two detent posi-
tions 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 actuates 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 actuat-
ing 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 13 seconds.
