POWER WINDOWS
DESCRIPTION
The power window system allows each of the door
windows to be raised and lowered electrically by
actuating a switch on the instrument panel (front
windows) or center console (rear windows). The front
window switch allows the front occupants to lock out
the individual rear switches from operation. The
power window system receives battery feed through a
circuit breaker in the fuse block, only when the igni-
tion switch is in the ON position.
The power window system includes the power win-
dow switches on the instrument panel (front win-
dows) and center console (rear windows), the circuit
breaker in the fuse block, and the power window
motors inside each door. For service of the mechani-
cal components, such as the regulator, window
tracks, or glass, refer to Body Group.
OPERATION
The front and rear door window lift motors are of
the permanent magnet type. A battery positive and
negative connection to either of the two motor termi-
nals 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 their
respective switch.

INSTALLATION
(2) Disconnect wire connector from back of power
window switch.
(3) Switch ignition to the ON position.
(4) Connect the clip end of a 12 volt test light to
Pin 4 of the window switch harness connector. Touch
the test light probe to Pin 3.
• If the test light illuminates, the wiring circuit
between the battery and switch is OK.
• If the lamp does not illuminate, first check 30
amp circuit breaker in the fuse block. If circuit
breaker is 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.
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 as necessary to
gain access to power window motor wire connector.
(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
