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 door
trim panel allows the driver to raise or lower either
front window. 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 door window lift motors are of the perma-

nent magnet type. A battery positive and negative
connection 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.

Each individual motor is grounded through the

master switch.

WINDOW DROP RELAY ASSEMBLY

DESCRIPTION

The Window Drop Relay Assembly allows the win-

dows to be automatically lowered when the convert-
ible top is raised or lowered.

It is mounted inside the drivers side door, behind

the door trim panel.

OPERATION

The window timer module will lower the windows

for 280 to 380 milliseconds when the top switch is
pressed up or down. This will lower the windows
approximately 1 to 3 inches so that the windows are
clear of the top while raising or lowering.

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 DROP RELAY ASSEMBLY
CONDITIONS

When testing for a voltage signal, use a digital

voltmeter, because the signal will last only 280 to
380 milliseconds. Place the ignition switch in the run
position with out engine running. Refer to Group 8W,
Wiring Diagrams circuit and pin locations (Fig. 2).

When pressing the top switch all windows do not
lower

(1) Check for battery voltage at Pin 1 and 2 of the

window timer module wire connector. If OK, go to
Step 2. If not OK, check circuit breaker top switch.
Repair as necessary.

(2) Using a ohmmeter, check Pin 9 of the window

timer module wire connector for ground. If OK, go to
Step 3. If not OK, repair as necessary.

(3) Using a digital voltmeter, check Pin 7 of the

window timer module wire connector for voltage sig-
nal for 280 to 380 milliseconds while pressing the top
switch. If not OK, replace the window timer module.
If OK, check power window circuit connections.

When pressing the top switch the front window(s)
do not lower

(1) Using a digital voltmeter, check Pin 4 of both

window motor relay wire connectors for voltage sig-
nal while pressing the top switch. If there is a
momentary voltage, go to Step 2. If not OK, window
timer relay.

(2) Using a ohmmeter, check Pin 6 of the both win-

dow motor relays wire connector for ground. If OK,
go to Step 3. If not OK, repair ground as necessary.

(3) Using a ohmmeter, check Pin 85 to Pin 86 of

window motor relay with connector disconnected for
open circuit. If OK, check power window circuit con-
nections. If open circuit replace window motor relay.

When pressing the top switch the rear window(s)
do not lower

(1) Using a digital voltmeter, check Pin 4 and Pin

6 of the window timer module wire connector for bat-
tery voltage while pressing the top switch. If no volt-
age replace the window timer module. If voltage,
check power window circuit connections.

WINDOW MOTOR

(1) Remove door trim panel, refer to Group 23

Body for removal 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.

(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-
