GENERAL INFORMATION
INTRODUCTION
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 (Fig. 1) by a black
wire attached to the left cowl panel. Refer to Group
8W, Wiring Diagrams from circuit information and
component locations.
Fig. 1 Power Window Master Switch
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

DIAGNOSIS AND TESTING
POWER VENT WINDOW MOTOR TEST
If the power vent window motor is receiving proper
current and ground and does not operate proceed
with motor test. Refer to Group 8W, Wiring Diagrams
for circuit information and component locations.
(1) Remove D-pillar trim panel necessary to gain
access to power vent window motor wire connector,
refer to Group 23, Body for proper procedures.
(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.
