CONTROL SWITCH/TIMER RELAY MODULE . . 1
GENERAL INFORMATION .................. 1REPAIR GRID LINES, TERMINALS AND PIGTAILS.3
SERVICE PROCEDURES ................... 1
GENERAL INFORMATION
For proper operation of the Rear Window Defogger
system refer to the Owner's Manual. Vehicles equipped with an electrically heated rear
window defogger also have a 40/90 amp generator. 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 as-
sembly is used on all models (Fig.1).
Circuit protection is provided by a fusible link, lo-
cated in the charging circuit, for the heated grid cir-
cuit 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, de-
cals or stickers. Normal glass cleaning solvents or
hot water used with rags or toweling is recom-
mended.
CONTROL SWITCH/TIMER RELAY MODULE
The control switch and timer relay are integrated
into a single panel or console mounted assembly. Ac-
tuating the switch energizes the circuit which allows
current to flow through the grid lines. Upon initial
actuation for approximately ten minutes, or until ei-
ther the switch or ignition is turned off. An indicat-
ing lamp illuminates a lens inlaid in the control
switch.
SERVICE PROCEDURES
Electrically heated rear window defogger operation
can be checked in vehicle in the following manner: (1) Turn ignition ON.
(2) Turn rear window defogger control switch ON.
(3) Using a ammeter on the battery. Turn the De-
fogger control switch ON, a distinct increase in am-
perage draw should be noted. (4) 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. (5) Using a DC voltmeter (Fig. 2) contact terminal
B with the negative lead, and terminal A with the
positive lead. The voltmeter should read 10-14 volts.

Fig. 2 Rear Glass Grid Line TestÐTypical
Ä REAR WINDOW DEFOGGER 8N - 1

(6) Steps (3, 4 or 5) above will confirm system op-
eration. Indicator light illumination means that
there is power available at the output of the relay
only, and does not necessarily verify system opera-
tion. (7) 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 fusible link and control cir-
cuit fuse is operational and all electrical connec-
tions are secure.
(8) 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.
(9) If turning the switch ON produces severe volt-
meter deflection, the circuit should be closely
checked for a shorting condition. (10) If the system operation has been verified but
indicator lamp does not light, replace the switch. (11) For detailed wiring information, refer to group
8W, Wiring Diagrams.
GRID TEST
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 be-
comes 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 ground con-
nection. (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 Posi-
tive lead. A reading of approximately 6 volts indi-
cates a line is good. A reading of 0 volts indicates a
break in line between Mid-Point C and terminal A.
A reading of 10-14 volts indicates a break between Mid-Point C and terminal B. Move toward break and
voltage will change as soon as break is crossed (Figs.
2 and 3).
CONTROL SWITCH/TIMER RELAY MODULE TEST
Control switch/timer relay module may be tested
in-vehicle or bench tested. In vehicle testing is ac-
complished in the following manner: (1) Remove the switch, relay assembly from the in-
strument panel or console, see Group 8E, Instrument
Panel and leave the switch connector plugged in. (2) Turn ignition ON.
(3) Using a DC voltmeter, with 0-15 range, check
voltage at terminals B, I and L. (Figs. 3 and 4). Ter-
minals B and I should confirm a voltage of 10 to 14
volts to ground when the ON switch is pressed. Ter-
minal L should confirm voltage to ground. When ter-
minals B and I show no voltage, trace circuit
upstream of switch/relay module for problem (wiring
cut, fusible link or circuit breaker inoperative, bulk-
head connector not operative, etc.) If terminal L in-
dicates voltage, place switch in Off position. If
voltage at L is still indicated or indicator lamp re-
mains on, the switch/relay module should be re-
placed. (4) If the relay checks out to this point, momen-
tarily operate switch to ON position. The indicator
lamp should come on and remain on for approxi-
mately 10 minutes. Terminal L should confirm volt-
age. If the indicator lamp fails to light or voltage at
terminal L is not confirmed the switch/relay module
should be replaced.

when either of two conditions occur: (1) The key is in the ignition switch and any of the
doors are open. The ignition switch does not have to
be ON. (2) The key is in the ignition switch and the head-
lamp are on.
AC, AG, AJ AND AY BODIES
With the ignition switch in the ON or OFF position
and the driver's door open the Body Controller will
ignore the command to lock the power door locks.
Once the key is removed, or the driver's door is
closed, the Body Controller will allow the power door
locks to lock. Refer to Body Diagnostic Procedure
Manual for further testing procedures.
8P - 6 POWER LOCKS Ä

(3) Activate the power door locks in both the
LOCK and UNLOCK directions. The horn will sound
after each activation. (4) Rotate the key in each of the door lock cylin-
ders to the unlock position. The horn will sound as
the switch closes, and again when it opens. There
must b e a 1 second delay between changing switch
states, or the horn will not sound.
² Press the LOCK button,horn will sound.
² Press the UNLOCK button, horn will sound.
(5) Cycle the key to the ignition RUN position. A
single horn pulse will indicate proper operation of
the ignition input. This will also take the module out
of the diagnostics mode. For any of these tests, if the
switch does not remain open or closed for at least 1
second, the horn will only sound once. The lack of a horn pulse, during any operation, in-
dicates a switch failure. Check for continuity at the
switch, if this is good, check for an open or shorted
wire between the switch and alarm module. Also,
check if a new powertrain control module has been
installed recently. Vehicle Theft Security System will
not function until 20 engine cranks. Whenever a Vehicle Theft Security System mal-
function occurs, first verify that the wire harness is
properly connected to all connectors before starting
normal diagnosis and repair procedures. Refer to Ve-
hicle Theft Security System Diagnosis Chart (Fig. 3).VEHICLE THEFT SECURITY SYSTEM MODULE
