DESCRIPTION AND OPERATION
POWER WINDOW SYSTEMS
DESCRIPTION
The power window system allows each of the door
windows to be raised and lowered electrically by
actuating a switch on the trim panel of each respec-
tive door. A master switch on the driver side front
door trim panel 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 circuit breaker in the junction block,
only when the ignition switch is in the On position.
The power window system includes the power win-
dow switches on each door trim panel, the circuit
breaker in the junction block, and the power window
motors inside each door. For service of mechanical
components, such as the regulator, lift plate, window
tracks, or glass refer to Group 23 - Body.
OPERATION
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 1 and Step 2
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.
