The purpose of this manual is to show
electrical schematics in a manner that
makes electrical troubleshooting easier.
Electrical components which work
together are shown together on one
schematic. The Wiper-Washer schematic,
for example, shows all of the electrical
components in one diagram. At the top of
the page is the fuse (positive) that powers
the circuit. The flow of current is shown
through all wires, connectors, switches,
and motors to ground (negative) at the
bottom of the page.
Within the schematic, all switches and
sensors are shown “at rest,” as though the
Ignition Switch were off. For identification,
component names are underlined and
placed next to or above each component.
Notes are included. describing how
switches and other components work.
The power distribution schematic shows
the current feed through all the
connections from the Battery and
Alternator to each fuse and the Ignition
and Light Switches. If the Power
Distribution schematic is combined with
any other circuit schematic, a complete
picture is made of how that circuit works.
The Ground Distribution schematics show
how several circuits are connected to
common grounds.
All wiring between components is
shown exactly as it exists in the vehicle;
however, the wiring is not drawn to scale.
To aid in understanding electrical
operation, wiring inside complicated
components has been simplified. The
“Solid State” label designates electronic
components.

6 SYSTEMATIC TROUBLESHOOTING
TROUBLESHOOTING PROCEDURE
1. Verify the Problem
Operate the problem circuit to check
the accuracy of the complaint. Note the
symptoms of the inoperative circuit.
2. Analyze the Problem
Refer to the schematic of the problem
circuit in the ETM. Determine how the
circuit is supposed to work by tracing
the current path(s) from the power feed
through the circuit components to
ground. Then based on the symptoms
you noted in step 1 and your under-
standing of circuit operation, identify
one or more possible causes of the
problem.
3. Isolate the Problem
Make circuit tests to prove or
disprove the preliminary diagnosis
made in step 2. Keep in mind that a
logical simple procedure is the key to
efficient troubleshooting. Test for the
most likely cause of failure first. Try to
make tests at points which are easily
accessible.
4. Repair the Problem
Once the specific problem is
identified, make the repair using the
proper tools and safe procedures.
5. Check the Problem
Operate the circuit to check for
satisfactory circuit operation. Good
repair practice calls for rechecking all
circuits you have worked on.
TROUBLESHOOTING TOOLS
Isolating the problem (Step 3 of
TROUBLESHOOTING PROCEDURES)
requires the use of a voltmeter and/or
ohmmeter. A voltmeter measures voltage
at selected points in a circuit. An ohm-
meter measures a circuit's resistance to
current flow. It has an internal battery that
provides current to the circuit under test.
Disconnect the car battery when using an
ohmmeter because the battery voltage will
cause theohmmeterto give false readings.
Also, do not use an ohmmeter on solid-
state components. The voltage that the
ohmmeter applies to the circuit could
damage these components.
TROUBLESHOOTING TESTS
Voltage Test
Thistestmeasures voltage in acircuit. By
taking measurements at several points
(terminals or connectors) along the circuit,
you can isolate the problem.
To take a voltage measurement, connect
the negative lead of the voltmeter to the
battery's negative terminal or other known
good ground. Then connect the positive
lead of the voltmeter to the point you want
to test. The voltmeter will measure the
voltage present at that point in the circuit.

SYSTEMATIC TROUBLESHOOTING /
Voltage Drop Test
Wires, connectors, and switches are
designed to conduct current with a
minimum loss of voltage. A voltage drop of
more than one volt indicates a problem.
To test for voltage drop, connect the
voltmeter leads to connectors at either end
of the circuit's suspected problem area.
The positive lead should be connected to
the connector closest to the power source.
The voltmeter will show the voltage drop
between these two points.

Continuity Test
To perform a continuity test, first
disconnect the car battery. Then adjust the
ohmmeter to read zero while holding the
leads together. Connect the ohmmeter
leads to connector or terminals at either
end of the circuit's suspected problem
area. The ohmmeter will show the
resistance across that part of the circuit.

Continuity Test
Short Test Using Voltmeter
Remove the blown fuse and disconnect
the load. Connect the voltmeter leads to
the fuse terminals. The positive lead
should be connected to the terminal
closest to the power source.
Starting near the POWER DISTRIBUTION
BOX, move thewire harness back and forth
and watch the voltmeter reading. If the
voltmeter registers a reading, there is a
short to ground in the wiring. Somewhere
in the area of the harness being moved, the
wire insulation isworn away and the circuit
is grounding.

Short Test Using Ohmmeter
Disconnect the battery. Adjust the
ohmmeter to read zero while holding the
leads together. Remove the blown fuse
and disconnect the load. Connect one lead
of the ohmmeter to the fuse terminal thatis
closest to the load. Connect the other lead
to a known good ground.
Starting near the POWER DISTRIBUTION
BOX, move thewire harness back and forth
and watch the ohmmeter reading. Low or
no resistance indicates a short to ground
in the wiring. Infinitely high resistance
indicates no short.

CIRCUIT DESCRIPTION
The Central Locking System is controlled
by the Central Locking Control Unit. This
unit senses when a lock switch is moved by a
key, and sends the appropriate signal to
drive the Motors. The Central Locking Con-
trol Unit controls the Door Locks, Gas Filler
Lock and Trunk Lock. The unit also has an
Inertia Switch which closes on impact
greater than 5g. If in RUN or START the
locks are then unlocked.
Lock
When the Key is inserted into a lock and
turned clockwise, the Lock switch moves to
LOCK and grounds terminal 7 of the Central
Locking Control Unit. The unit then acti-
vates the Lock Relay and applies voltage
from Fuse 27 to the Lock Motor, which is
grounded through the Central Locking Con-
trol Unit terminal 2. The Lock Motor then
pulls the lock down. The door locks also con-
trol the Trunk Lock and Gas Filler Lock.
CENTRAL LOCKING 5126A-3
Unlock
When the key is turned counterclockwise,
terminal 6 of the Central Locking Control
Unit is grounded through the Lock Switch.
The Central Locking Control Unit then acti-
vates the Unlock Relay and applies voltage
from Fuse 27, through terminal 2 to the Lock
Motor. The motor is grounded through the
Cental Locking Control Unit terminal 1. The
polarity is reversed and the motor pushes the
lock up.
Unlock Inhibit
When the key is inserted into the Driver's
Lock and turned clockwise past the LOCK
position, the Unlock Inhibit mechanism is
engaged. This mechanically inserts a bar into
the driver's lock and prevents unlocking
through use of the Safety Catch Button.
When in the Unlock Inhibit position, ground
is applied to the Unlock Inhibit motors in the
other lock units. The Central Locking Con-
trol Unit is grounded at terminal 10 and then
activates the Lock Relay. Voltage is applied
to the Unlock Inhibit motors through termi-
nal 1. They are now activated and engage the
other Unlock Inhibit mechanisms. The direc-
tion of the motors is reversed when the doors
are unlocked (see Unlock).
Trunk Lock
The Trunk Lock operates in a manner similar
to the Door Locks.

CIRCUIT OPERATION
The Water Shut-Off Solenoid controls the
flow of engine coolant through the heater core.
When the solenoid is energized, coolant flow is
shut off to allow maximum cooling from the air
conditioning system. The Water Shut-Off Sole-
noid is controlled by the Hot Water Cut-Off
Switch, which is part of the A/C Control Panel
TEMP Control.
Battery voltage is applied through Fuse 20 to
the Hot Water Cut-Off Switch when the Igni-
tion Switch is in RUN. The Hot Water Cut-Off
Switch is closed when the TEMP Control is
rotated fully counterclockwise (coldest posi-
tion), and opens when the control is rotated
more than 20 degrees in a clockwise direction.
When the switch is closed, battery voltage is
applied through the A/C In-Line Fuse to the
Water Shut-Off Solenoid. The solenoid is ener-
gized and shuts off the coolant flow through the
heater core.
The Water Shut-Off Solenoid and A/C In-Line
Diode are protected by the A/C In-Line Fuse. If
any failures occur in the solenoid, the Fuse will
isolate them to prevent the failures from affect-
ing other parts of the heating and air condition-
ing circuits.

CIRCUIT OPERATION
With the Ignition Switch in RUN, battery
voltage is applied to the Control Switches and
the Blower Speed Control through the GN/BR
wires. If either the A/C Select Switch or the
Fresh/Recirculating Air Switch are ON or the
Blower Speed Control is in position 1, battery
voltage is applied through the YL wire to the
Blower Resistors and the Blower Motor.
The Blower Motor is a variable speed motor
which runs at a speed proportional to the volt-
age applied to it. With all of the Blower
Resistors in the circuit, the voltage applied to
the motor is reduced so the motor runs at a low
speed.
As the Blower Speed Control is moved
through positions 2 and 3, some of the resistors
are bypassed, allowing more voltage to be
applied to the Blower Motor, which then runs at
a higher speed. When the Blower Speed Control
is moved to position 4, battery voltage is
applied directly to the Blower Motor, which
then runs at maximum speed.
The Blower Resistors dissipate heat because
of the current flowing through them. They are
cooled by the air flow from the blower. If there
is insufficient air flow to cool the resistors, the
safety switch will open, shutting the Blower
Motor off until the resistors have cooled.
TROUBLESHOOTING HINTS
¢ Try the following checks before doing the Sys-
tem Diagnosis.
1. Check Fuse 20 by visual inspection.
2. If Blower will run in high only, check the
Blower Resistors’ Safety Switch for an open.

voltage is applied to terminal 7 of the Control
Switches, the normally open contacts of the LH
Fresh/Recirculating Air Relay, and the nor-
mally closed contacts of the RH Fresh/Recir-
culating Air Relay. If the Fresh/Recirculating
Air Switch is not depressed (open), battery volt-
age is applied through the normally closed con-
tacts of the RH Fresh/Recirculating Air Relay
to both Fresh/Recirculating Air Flap Door
Motors and then to ground through the nor-
mally closed contacts of the LH Fresh/Recir-
culating Air Relay. Both motors operate and
move the Fresh/Recirculating Air Flap Doors
to position A, allowing fresh air to enter the
blower.
When the Fresh/Recirculating Air Switch is
depressed (closed), battery voltage is applied
through the switch to both the LH and RH
Fresh/Recirculating Air Relay coils. Both
relays are energized. Battery voltage is then
applied through the closed contacts of the LH
Fresh/Recirculating Air Relay to the Flap Door
Motors, and to ground through the closed con-
tacts of the RH Fresh/Recirculating Air Relay.
Since the voltage is now applied to the Flap
Door Motors in the opposite direction, the
motors reverse direction and move the Fresh/
Recirculating Air Flap Doors to position B,
allowing only recirculating air to enter the
blower. Both of the Air Flap Door Motors
remain energized continuously. When the doors
reach the end of their travel, the motors stall
and hold the doors in position.

CIRCUIT OPERATION
When the Ignition Switch isin RUN, battery
voltage is applied through Fuse 20 to the Com-
pressor Enable Switch. This switch is located in
the A/C Control Panel and is closed when either
the center or lower slide levers are moved about
Ys of the distance away from the left position,
This ensures that the A/C Compressor does not
run unless there is enough air flow to prevent
freezing of the evaporator.
When the A/C Select Switch is pressed and
the Compressor Enable Switch is closed, volt-
age is applied to terminal 3 of the Evaporator
Temperature Regulator. The Evaporator Tem-
paerature Regulator applies voltage from ter-
minal 5 to the Compressor Clutch through the
High Pressure Cut-Out Switch, the Low Pres-
sure Cut-Out Switch, and the Temperature
Switch (M3 engine).
The High Pressure Cut-Out Switch opens if
refrigerant pressure rises to a value which is too
high for normal operation. The Evaporator
Temperature Regulator also monitors the cur-
rent through the High Pressure Cut-Out
Switch. If terminal 2 of the Evaporator Tem-
perature Regulator does not receive voltage
when the clutch is engaged, the Evaporator
Temperature Regulator will remove ground
from the relay. The relay’s contacts will open,
removing battery voltage to the Compressor
Clutch. The Compressor Clutch will disengage.
The Evaporator Temperature Regulator will
again provide ground for the relay (after a short
time delay) and the Compressor Clutch will turn
on again. This on-off cycling of the Compressor
Clutch will continue if termianl 2 does not
receive an input.
COMPRESSOR CONTROLS
The Temperature Switch (M3 Engine) opens
to remove the compressor load from the engine
if the engine coolant temperature rises above
226°F (108°C). The Evaporator Temperature
Sensor signals the Evaporator Temperature
Regulator to de-energize the Compressor
Clutch when evaporator temperature is low
enough for freezing to result.
Clutch Diode
Whenever the Compressor Clutch is de-ener-
gized, the collapsing magnetic field induces a
voltage in the winding. The Clutch Diode pro-
vides a path for the resulting current.
TROUBLESHOOTING HINTS

CIRCUIT OPERATION
With the Ignition Switch in ACCY, RUN or
START, Fuse 12 provides voltage to turn on
the three components in the system. When the
Radio Switch is on, voltage is applied to the
Radio, the Power Antenna Raise/Lower Input,
and the Amplifier. This voltage is used to con-
trol the individual unit's main power supply.
When the Raise/Lower Input of the Power
Antenna receives voltage, power is supplied
from Fuse 28 to run the motor and raise the
Antenna. When voltage is no longer present at
the Raise/Lower Input, the Antennais lowered.
Fuse 21 constantly supplies voltage to the
Memory Power Input of the Radio. This allows
the Radio to maintain the present settings
while it is turned off.
The Amplifier receives constant power at ter-
minal 11 from Fuse 27. When the Radio is on,
voltage is applied to terminal 13 to enable the
Amplifier.
The actual Radio signal originates at the
Antenna. It is supplied to the Radio, processed,
and output from the Left Channel and Right
Channel Outputs to the Fader Control. The
Fader Control alters the front to rear volume by
decreasing the resistance to the desired higher
volume outputs. The signal is then input to the
Left Front, Left Rear, Right Front, and Right
Rear Inputs to the Amplifier. After amplifica-
tion, the signal is output to the corresponding
speakers.
TROUBLESHOOTING HINTS
* Try the following checks before doing the Sys-
tem Check.
1. Check power input to the Radio by observ-
ing if Instrument Cluster Indicators light.
2. Check power input to Antenna by observ-
ing the Cigar Lighter.
3. Check memory power to Radio by checking
operation of the Glove Box Light.
4. Check power input to the Amplifier.
If Fader Control has no effect, but sound is
heard from all speakers, replace the Fader
Control.
6. Check that the Antenna is properly con-
nected.
7. Before troubleshooting a suspect Speaker,
check all connections to that Speaker.
8. If display shows “CODE” and Radio will
not operate, the individual Anti-Theft Code
must be entered. Refer to “Anti-Theft”
instruction booklet.
9. Check Radio Fuse located on back of Radio.
10. Check Amplifier Fuse located on back of
Amplifier.
