GENERAL
INFORMATION

Before starting diagnosis and repair procedures for
a speed control malfunction, verify that the speed
control wire harness is properly connected to all con­ nectors. Refer to Diagnosis Chart.

ROAD
TEST
Road test vehicle to verify reports of speed control
system malfunction. The road test should include at­
tention to the speedometer. Speedometer operation should be smooth and without flutter at all speeds. Flutter in the speedometer indicates a problem
which might cause surging in the speed control sys­
tem. The cause of any speedometer deficiencies should be corrected before proceeding.

INOPERATIVE SYSTEM
If road test verifies a system problem and the
speedometer operates properly, check for:
• loose electrical and vacuum connections at the
servo.

• check for correct installation of the vacuum check
valve in the hose from servo to vacuum source (Gas
Engine Only). The word VAC on the valve must
point toward the vacuum source. • corrosion that should be removed from electrical
terminals and a light coating of Mopar Multi-Pur­
pose Grease, or equivalent, applied. • secure attachment of both ends of speed control ca­

ble.

CHECKING
FOR DIAGNOSTIC TROUBLE CODE
(1) When trying to verify a speed control system
electrical problem, use a DRB II Scan Tool to find
the cause. Refer to Powertrain Diagnostic Procedures manual. If the DRBII is not available, the Diagnostic Trou­
ble Code (DTC) may be determined with the follow­ ing method: (a) With key inserted in ignition switch, cycle
switch to ON position 3 times. On third cycle, leave
switch in ON position. (b) After switch has been cycled 3 times, observe
Malfunction Indicator Lamp (CHECK ENGINE) on instrument cluster. If a DTC is present, the code

Three flashes in rapid succession, a slight
pause, then 4 flashes in rapid succession would in­ dicate DTC 34.
(2) If a DTC 34 is observed, perform the tests in
the sections Electrical Tests at Servo and Electrical
Tests at Powertrain Control Module.
If a DTC 15 is observed, perform the test for a
faulty Vehicle Speed Sensor.
(3) If a fault code 11 is observed (Diesel only), per­
form the test for a faulty engine speed sensor. Refer
to the Powertrain Diagnostics Procedures Manual.
(4) Correct any problems found when performing
these tests and recheck for DTC if changes were made.

VEHICLE SPEED SENSOR TEST
For testing of the Vehicle Speed Sensor and related
components refer to the Powertrain Diagnostic Proce­
dures manual.

VEHICLE SPEED CONTROL SYSTEM ELECTRICAL
TESTS
Vehicle speed control systems may be tested using
two different methods. One involves the use of the DRBII Scan Tool. If this test method is desired,
please refer to the Powertrain Diagnostic Procedures manual. The other test method uses a voltmeter. The volt­
meter method is described in the following tests.
If any information is needed concerning wiring, re­
fer to Group 8W - Wiring Diagrams.

CAUTION:
When test probing
for
voltage
or
conti­nuity
at
electrical
connectors, care must
be
taken
not
to
damage connector, terminals,
or
seals.
If

these components
are
damaged,
intermittent
or
complete system
failure
may
occur.
ELECTRICAL
TESTS
AT
SERVO
(1) Turn ignition switch to ON position.
(2) Push speed control switch to ON position.

GENERAL
INFORMATION
The electrically heated rear window defogger
is

available
on
Ramcharger with sunscreen glass only. The system consists
of a
rear window with
two
ver­
tical
bus
bars
and a
series
of
electrically connected
grid lines baked
on the
inside surface. Circuit protection
for the
heated grid circuit
is
pro­
vided
by a 18
gauge fusible link wire located
in the

engine compartment.
The
relay circuit
is
protected
by
a 20 amp
fuse, located
in the
fuse block. When
the
rear window defogger switch
is
placed
in

the
ON
position, current
is
directed
to
rear window
grid lines.
The
heated grid lines
in
turn heat
the

rear window
to
clear
the
surface
of fog or
snow.

CAUTION;
Grid lines
can be
damaged
or
scraped
off
with
sharp instruments. Care should
be
taken

SYSTEM
DESCRIPTION CONTROL
SWITCH/TIMER
RELAY MODULE
The control switch
and
timer relay
are
integrated
into
a
single panel mounted assembly. Actuating
the
switch energizes
the
electronic timing circuit. This
allows current
to
flow through
the
grid system
for

approximately
10
minutes,
or
until either
the
control
switch
or
ignition
is
turned
off. An
indicating lamp
illuminates
a
lens inlaid
in the
control switch.

TEST PROCEDURES

SYSTEM
TEST
Electrically heated rear window defogger operation
can
be
checked in-vehicle
in the
following manner: (1) Turn
the
ignition
ON.

(2) Turn rear window defogger control switch
ON.

(3) Monitor vehicle voltmeter. With
the
control
switch
ON, a
distinct needle deflection 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 3 to 4
minutes
of
oper­ation. (5) Contact negative lead
of a DC
voltmeter
(Fig.

1),
to
terminal
"B"
(passenger side). Contact positive
lead
to
terminal
"A"
(driver side).
The
voltmeter
should read
10-14
volts. Only steps
(3) and (4) or (5)
above will confirm sys­
tem operation. Indicator light illumination means
that there
is
power available
at the
output
of the re­
lay only,
and
does
not
verify system operation.
If rear window defogger does
not
operate,
the
prob­
lem should
be
isolated
in the
following manner:
(1) Confirm that ignition switch
is ON.

Test (2) Ensure that heated rear window feed wire
is

connected
to
terminal
or
pigtail
and
that ground wire
is
in
fact grounded.
(3) Ensure that fuse
is
operational
and all
electri­
cal connections
are
secure.
When above steps have been completed
and the

system
is
still inoperative,
one or
more
of the
follow­
ing
is
defective:
(a) Control switch/timer relay module.

REAR WINDOW DEFOGGER

• (b) Rear window grid lines (all grid lines would
have to be broken) or one of the feed wires are not
connected for the system to be inoperative.
The following paragraphs outline component check­
out procedures.
If turning the switch ON produces severe voltmeter
deflection, the circuit should be closely checked for a shorting condition. If system operation has been verified but indicator
bulb does not light, check and replace bulb.
For detailed wiring information, refer to Group 8W
- Wiring Diagrams.

REAR
WINDOW GRID LINES TEST
Horizontal grid lines and vertical bus bar lines
printed and baked on inside surface of rear window glass (Fig. 1) comprise an electrical parallel circuit.
The electrically conductive lines are made of a silver- ceramic material. When baked onto glass they be­
come bonded to the glass and are highly resistant to abrasion. It is possible, however, that a break may
exist or occur in an individual grid line resulting in
no current flow through the line. To detect breaks in
grid lines, the following procedure is required: (1) Turn ignition on and push control switch to
ON. Indicator light should come on. (2) Contact negative lead of a DC voltmeter, to
vertical bus bar connecting grid lines on passenger side of vehicle (point A of Fig. 1). Contact positive
lead of voltmeter, to vertical bus bar on driver side of
vehicle (point B of Fig. 1). Voltmeter should read 10-14 volts. (3) With negative lead of voltmeter, contact a good
body ground point. Voltage reading should not change. A different reading indicates a poor ground connection. (4) Connect negative lead of voltmeter to Point A
on passenger side bus bar and touch each grid line at
Mid-Point with positive lead. A reading of approxi­ mately 6 volts indicates a line is good. A reading of 0
volts indicates a break in line between Mid-Point C and Point B. A reading of 10-14 volts indicates a
break between Mid-Point C and ground Point A. Move toward break and voltage will change as soon as break is crossed.

CONTROL SWITCH/TIMER 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 switch from instrument panel (refer to
Control Switch Replacement) and leave switch con­
nector plugged in. (2) Turn ignition ON.
(3) Using a DC voltmeter, check voltage at termi­ nals B, I and L (Figs. 2 and 3). Terminals B and I
should confirm a voltage of 10 to 14 volts to ground.
Terminal L should confirm 0 volts to ground. When terminals B and I show no voltage, trace circuit up­
stream of switch/relay module for cause:
• wiring cut
• fusible link faulty
• circuit breaker inoperative
• bulkhead connection bad, etc. If terminal L indicates voltage, place switch in
OFF position. If voltage at L is still indicated or in­
dicator lamp remains on, switch/relay module should
be replaced.

(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.
Bench checking of the relay may be accomplished
in the following manner. By following the in-vehicle
procedure except Step 2: With a DC power supply, apply 12 volts to terminal B and I and ground termi­
nal G.
