DESCRIPTION
The door track and rack assembly provides a mat-
ing rack gear (Fig. 22) for the lower drive unit to
engage. The track also accepts the lower hinge roll-
ers, which helps support the weight of the sliding
door as well as providing a smooth surface for the
hinge rollers to move upon. The lower door track is a
replaceable component.
OPERATION
With the start of a power sliding door open cycle,
the door motor drives the flex drive assembly. The
flex drive assembly drives the lower drive unit. A
metal drive gear which is part of the lower drive
unit, meshes with the door track rack teeth and
moves the sliding door into the full open position.
The same operation repeats itself, during a power
close cycle only the system rotates in the opposite
direction.

POWER WINDOWS
DESCRIPTION
The Power Window System is activated through
switches mounted on the driver and passenger door
panels.
OPERATION
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.
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 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.
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 withmotor test. Refer to the appropriate wiring informa-
tion.
(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.
RSPOWER WINDOWS8N-61
(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.
²If the test light illuminates, the wiring circuit
between the battery and switch is OK.
²If 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.
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.
(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/

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.
