DESCRIPTION AND OPERATION
INTRODUCTION
For proper operation of the Rear Window Defogger
system refer to the Owner's Manual.
The system consists of a rear glass with two verti-
cal bus bars and a series of electrically connected
grid lines fired on the inside surface. A control switch
and a timer relay combined into a single assembly is
used on all models (Fig. 1).
Circuit protection is provided by a maxi fuse,
located in the Power Distribution Center, for the
heated grid circuit and by a fuse for the relay control
circuit.
When the switch is turned to the ON position, cur-
rent is directed to the rear defogger grid lines. The
heated grid lines heat the rear glass to clear the sur-
face of fog or frost.
CAUTION: Grid lines can be damaged or scraped
off with sharp instruments, care should be taken in
cleaning glass or removing foreign materials,
decals or stickers. Normal glass cleaning solvents
or hot water used with rags or toweling is recom-
mended.
REAR WINDOW DEFOGGER SWITCH
The rear window defogger switch is a control
switch and timer relay integrated into a single panel
mounted assembly. Actuating the switch energizes
the circuit which allows current to flow through the
grid lines. Upon initial actuation for approximately
eight to ten minutes, or until either the switch or
ignition is turned off. An indicating lamp illuminates
a lens inlaid in the control switch.
DIAGNOSIS AND TESTING
DEFOGGER SYSTEM
Electrically heated rear window defogger operation
can be checked in vehicle in the following manner:
(1) Turn ignition switch to the ON position.
(2) Connect an ammeter in series with the battery.
Push the defogger control switch to the ON position.
A distinct increase in amperage draw should be
noted.
(3) The rear window defogger operation can be
checked by feeling the glass. A distinct difference in
temperature between the grid lines and adjacent
clear glass can be detected in three to four minutes
of operation.
(4) Using a DC voltmeter, connect negative lead to
Point B, and the positive lead to Point A (Fig. 2). The
voltmeter should read 10-14 volts.
(5) Step 2, Step 3 or Step 4 above will confirm
system operation. Indicator light illumination means
that there is power available at the output of the
relay only, and does not necessarily verify system
operation.
Fig. 1 Rear Window Defogger
PLELECTRICALLY HEATED SYSTEMS 8N - 1

(6) If turning the switch ON produced no distinct
current draw on the ammeter the problem should be
isolated in the following manner:
(a) Confirm the ignition switch is ON.
(b) Ensure that the heated rear glass feed wire
is connected to the terminal or pigtail and that the
ground wire is in fact grounded.
(c) Ensure that the maxi-fuse and control circuit
fuse are OK and all electrical connections are
secure.
(7) When the above steps have been completed and
the system is still inoperative, one or more of the fol-
lowing is defective:
(a) Control switch/timer relay module.
(b) All rear window grid lines would have to be
broken or one of the feed wires are not connected
for the system to be inoperative.
(8) If turning the switch ON produces severe volt-
meter deflection, the circuit should be closely checked
for a shorting condition.
(9) If the system operation has been verified but
indicator lamp does not light, replace the switch.
(10) For detailed wiring information, refer to group
8W, Wiring Diagrams.
GRID LINES
The horizontal grid lines and vertical bus bar lines
printed and fired on inside surface of rear window
glass (Fig. 2) comprise an electrical parallel circuit.
The electrically conductive lines are composed of a
silver-ceramic material which when fired on glass
becomes bonded to the glass and is highly resistant
to abrasion. It is possible, however, that a break may
occur in an individual grid line resulting in no cur-
rent flow through the line. To detect breaks in grid
lines the following procedure is required:
(1) Turn ignition ON and turn control switch to
ON. The indicator light should come on.(2) Using a DC voltmeter with 0-15 volt range,
contact terminal B with negative lead of voltmeter.
With positive lead of voltmeter, contact terminal A
(Fig. 2). The voltmeter should read 10-14 volts. A
lower voltage reading indicates a poor connection in
the feed or the ground circuit.
(3) With negative lead of voltmeter, contact a good
body ground point. The voltage reading should not
change.
(4) Connect negative lead of voltmeter to terminal
B and touch each grid line at Mid-Point with Positive
lead. A reading of:
²Approximately 6 volts indicates the line is OK
²0 volts indicates a break in line between Mid-
Point C and terminal A
²10-14 volts indicates a break between Mid-Point
C and terminal B
Move the lead toward the break and voltage will
change as soon as break is crossed. Refer to (Fig. 2)
and (Fig. 3).
REAR WINDOW DEFOGGER SWITCH
The rear window defogger switch may be tested in-
vehicle or bench tested. In vehicle testing is accom-
plished in the following manner:
(1) Remove the switch from the instrument panel
but leave the switch connected, refer to Group 8E,

GENERAL INFORMATION
INTRODUCTION
The window lift motors are of the permanent mag-
net 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.
DIAGNOSIS AND TESTING
WIRING TEST
The following wiring test determines whether or
not voltage is continuous through the body harness
to switch.
Remove switch for testing. Connect a voltmeter
positive lead to Pin 4 and negative lead to Pin 3 of
the switch connector (Fig. 1). Turn ignition switch to
the ON position. Voltmeter should read battery volt-
age. If OK, go to Window Switch Test. If not OK,
check the 30 amp circuit breaker behind the fuse
block or for a broken wire. For wiring, specific con-
nector type and location, refer to Group 8W, Wiring
Diagrams.
WINDOW SWITCH TEST
Remove the switch from its mounting, refer to the
Window Switch Removal and Installation proce-
dures.. Using an ohmmeter, refer to the test proce-
dures below, Driver Side or Passenger Side Window
Switch Continuity Test to determine if continuity is
correct (Fig. 2) and (Fig. 3). If the results are not
obtained, replace the switch.
WINDOW MOTOR TEST
(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 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, disconnect the
regulator from the glass lift plate. Remove the two
attaching nuts, and slide the window up and down by
hand. This check can not be made on a four door
vehicle.
