GENERAL INFORMATION
INTRODUCTION
Front and rear door window lift motors are of the
permanent magnet type. A battery positive and neg-
ative connection to either of the two motor terminals
will cause the motor to rotate in one direction.
Reversing current through these same two connec-
tions will cause the motor to rotate in the opposite
direction.
Each individual motor is grounded through the
master switch.
DIAGNOSIS AND TESTING
VOLTAGE
The following circuit test sequence determines
whether or not voltage is continuous through the
body harness to switch.
(1) Remove the driver door trim panel. Refer to
Group 23, Body for proper procedures.
(2) Carefully separate wiring harness connector
from switch body. Refer to Group 8W, Wiring Dia-
grams.
(3) Using a voltmeter, connect the ground lead to
the Pin 10 of the wiring harness connector.
(4) Using the positive lead, check Pin 1 of the har-
ness connector for battery voltage. If OK, go to Win-
dow Switch Test below. If not OK, check 20 amp
circuit breaker in the Junction Block, if the circuit
breaker is OK, repair wire as necessary. For wiring,
specific connector type and location, refer to Group
8W, Wiring Diagrams.
WINDOW MOTOR
(1) Remove door trim panel, refer to Group 23,
Body for Removal and Installation procedures.
(2) Connect positive (+) lead from a test battery to
either of the two motor terminals.
(3) Connect negative (-) lead from test battery to
remaining motor terminal.
(4) The motor should now rotate in one direction to
either move window up or down.
(a) If window happens to already be in full UP
position and motor is connected so as to move it in
UP direction no movement will be observed.
(b) Likewise, motor connected to move window
in DOWN direction no movement will be observed
if window is already in full DOWN position.
(c)
Reverse battery leads in Step 2 and Step 3
and window should now move. If window does not
move, remove motor. See below for motor removal
from vehicle.
(5) If window moved completely up or down, the
test leads should be reversed one more time to com-
plete a full window travel inspection.
(6) If window does not move, check to make sure
that it is free.
(7) It is necessary that the window be free to slide
up and down in the glass channels. If the window is
not free to move up and down, the window lift motor
will not be able to move the glass.
(8) To determine if the glass is free is to disconnect
the regulator from the glass lift plate. Remove the
two attaching screws, and slide the window up and
down by hand.

WINDOW SWITCH
For switch testing, remove the switch from its
mounting, refer to Switch Removal. Using an ohm-
meter, refer to Window Switch Continuity Charts to
determine if continuity is correct (Fig. 1) and (Fig. 2).
If the results are not obtained, replace the switch.
The master window switch has an Auto-Down fea-
ture. Actuation of the master switch to the second
down detent position will move the drivers side win-
dow completely down. The electronic switch will
automatically disconnect the motor approximately 1
second after the window bottoms out. Failure of the
electronic switch to detect stall current, will cause
the switch to disconnect after approximately 15 sec-
onds of operation. The auto down function can be
canceled by any movement of the switch.
REMOVAL AND INSTALLATION
WINDOW MOTOR
WARNING: DO NOT HAVE ANY HANDS OR FIN-
GERS IN SECTOR GEAR AREA WHERE THEY CAN
BE PINCHED BY SMALL MOVEMENTS OF REGULA-
TOR LINKAGE.
REMOVAL
(1) Open hood and disconnect the negative battery
cable remote terminal from the remote battery post
(Fig. 4).
(2) Move the window to the full-up position, if pos-
sible.
(3) Remove door trim panel and window regulator,
refer to Group 23, Body for Removal and Installation
procedures.
WARNING:
FAILURE TO CLAMP THE SECTOR
GEAR TO THE MOUNTING PLATE WHEN REMOV-
ING THE MOTOR CAN RESULT IN INJURY.
(4) Disconnect wiring connector from motor.
(5) Secure the sector gear and mounting plate with
a C clamp or similar clamping tool. This will prevent
a sudden and forceful movement of the regulator
when the motor is removed.
(6) Remove three mounting screws that hold motor
gearbox to regulator (Fig. 3).
(7) Remove motor from regulator.
INSTALLATION
(1) Install new motor on regulator by positioning
motor gearbox so that it engages regulator sector
teeth.

DIAGNOSIS AND TESTING (Continued)
(2) A slight rotational or rocking movement may
be necessary to bring three motor gearbox screw
holes into proper position.
(3) Install three gearbox screws and one tie down
bracket screw, if applicable. Tighten to 5.6 to 8 N·m
(50 to 70 in. lbs.) torque.
(4) Install regulator, using the switch, test opera-
tion of motor.
WINDOW SWITCH
MASTER SWITCH
REMOVAL
(1) Open hood and disconnect the negative battery
cable remote terminal from the remote battery post
(Fig. 4).

dures.
(3) Remove three mounting screws.
(4) Remove switch and disconnect wire connector.
INSTALLATION
For installation, reverse the above procedures.
PASSENGER SWITCH
REMOVAL
(1) Open hood and disconnect the negative battery
cable remote terminal from the remote battery post
(Fig. 4).
(2) Remove passenger door trim panel. Refer to
Group 23, Body for Removal and Installation proce-
dures.
(3) Disconnect switch wire connector.
(4) Remove switch from bezel.
INSTALLATION
For installation, reverse the above procedures.
REAR DOOR SWITCHES
REMOVAL
(1) Open hood and disconnect the negative battery
cable remote terminal from the remote battery post
(Fig. 4).
(2) Open rear door.
(3) Using a trim stick (special tool #C-4755), gently
pry up on rear edge of switch pushing forward as you
pry up on switch bezel.
(4) Pull switch up and out of rear door trim panel.
(5) Using a trim stick, gently pry out on retaining
tabs on side of switch connector and pull connector
from switch.
(6) Remove switch from vehicle.
