Before performing the following tests, perform the
ATC Function Test using the DRBIIItand refer toCooling for the procedures to check the radiator cool-
ant level, serpentine drive belt tension, radiator air
flow and the radiator fan operation.
MAXIMUM HEATER OUTPUT
Engine coolant is provided to the heater core
through a heater valve and heater hose. With the
engine idling at normal operating temperature, set
the heater-A/C controls as follows:
²Temperature control in the full hot position
²Mode control in the floor heat position
²Blower motor control in the highest speed posi-
tion
Using a test thermometer, check the temperature
of the air being discharged at the floor outlets. Com-
pare the test thermometer reading to the Tempera-
ture Reference chart.

If the floor outlet air temperature is insufficient,
check for a faulty heater valve (perform ATC Func-
tion Test) and verify that the cooling system is oper-
ating to specifications (Refer to 7 - COOLING/
ENGINE/COOLANT - DIAGNOSIS AND TESTING).
Both of the heater hoses should be HOT to the touch
(the coolant return heater hose should be slightly
cooler than the supply hose. If the coolant return
hose is much cooler than the supply hose, locate and
repair the engine coolant flow obstruction in the
heater system.
POSSIBLE LOCATIONS OR CAUSE OF
OBSTRUCTED COOLANT FLOW
²Pinched or kinked heater hoses.
²Improper heater hose routing.
²Plugged heater hoses or supply and return ports
at the cooling system connections.
²Inoperative or stuck heater water valve.
²Plugged heater core.If proper coolant flow is verified, and heater floor
outlet air temperature is insufficient, a mechanical
problem may exist.
POSSIBLE LOCATIONS OR CAUSE OF
INSUFFICIENT HEAT
²An obstructed cowl air intake.
²Obstructed heater system outlets.
²Heater water valve not functioning properly.
TEMPERATURE CONTROL
If outlet air temperature cannot be adjusted with
the A/C-heater temperature control, one of the follow-
ing could require service:
²Faulty A/C-heater control switch.

STANDARD PROCEDURE
STANDARD PROCEDURE - COMPRESSOR
CLUTCH AIR GAP
If a new clutch plate and/or clutch pulley are being
used, the air gap between the clutch plate and clutch
pulley must be checked using the following proce-
dure:
(1) Using feeler gauges, measure the air gap
between the clutch plate and the clutch pulley fric-
tion surfaces.
(2) If the air gap is not between 0.5 and 0.9 mm
(0.020 and 0.035 in.), add or subtract shims until the
desired air gap is obtained.
NOTE: The shims may compress after tightening
the compressor shaft bolt. Check the air gap in four
or more places on the clutch plate to verify that theair gap is still correct. Spin the clutch pulley before
making the final air gap check.
STANDARD PROCEDURE - COMPRESSOR
CLUTCH BREAK-IN
After a new compressor clutch has been installed,
cycle the compressor clutch approximately twenty
times (five seconds on, then five seconds off). During
this procedure, set the heater-A/C control in the
Recirculation Mode, the A/C button in the on posi-
tion, the blower motor switch in the highest speed
position, and the engine speed at 1500 to 2000 rpm.
This procedure (burnishing) will seat the opposing
friction surfaces and provide a higher compressor
clutch torque capability.
REMOVAL
The refrigerant system can remain fully-charged
during compressor clutch, pulley, or coil replacement.
The compressor clutch can be serviced in the vehicle.
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the serpentine drive belt (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
REMOVAL).
(3) Disconnect the engine wire harness connector
for the compressor clutch coil from the clutch coil
wire harness connector on the top of the compressor.
(4) Disengage the retainer on the engine wire har-
ness compressor clutch coil lead from the bracket on
the top of the compressor.
(5) Remove the bolt that secures the compressor
clutch to the compressor shaft (Fig. 2). If necessary, a
band-type oil filter wrench or strap wrench can be
placed around the clutch plate to aid in bolt removal.

(2) Examine the friction surfaces of the clutch pul-
ley and the clutch plate for oil contamination. If the
friction surfaces are oily, the clutch pulley and clutch
plate should be replaced. Also inspect the shaft and
nose area of the compressor for oil. Remove the felt
packing from around the compressor shaft in the
compressor front cover. If the felt is saturated with
oil, the compressor front shaft seal is leaking and the
compressor will also have to be replaced.
(3) Check the clutch pulley bearing for roughness
or excessive leakage of grease. Replace the clutch
pulley and clutch plate if the bearing is faulty.
INSTALLATION
(1) Align the dowel pin on the back of the clutch
field coil with the hole in the compressor front cover,
and position the clutch coil onto the compressor. Be
certain that the cluch coil wire harness leads are
properly oriented and routed so that they are not
pinched between the compressor front cover and the
clutch coil.
NOTE: A new snap ring must be used to secure the
clutch coil to the compressor. The bevel side of the
snap ring must face outward.
(2) Using snap ring pliers (Special Tool C-4574 or
equivalent), install the external snap ring that
secures the clutch coil to the front cover of the com-
pressor. The bevel side of the snap ring must be fac-
ing outward and both snap ring eyelets must be
oriented to the right or left of the clutch coil dowel
pin on the compressor. Be certain that the snap ring
is fully and properly seated in the groove.
CAUTION: If the snap ring is not fully seated in the
groove it will vibrate out, resulting in a clutch fail-
ure and severe damage to the compressor front
cover.
(3) Install and tighten the screw that secures the
clutch coil wire harness connector bracket and
ground clip to the top of the compressor housing.
(4) Install the pulley onto the front of the compres-
sor. If necessary, place a block of wood on the friction
surface and tap gently with a hammer (Fig. 6).
CAUTION: Do not mar the friction surfaces of the
pulley.
(5) Using snap ring pliers (Special Tool C-4574 or
equivalent), install the external snap ring (bevel side
facing outward) that secures the clutch pulley to the
front cover of the compressor. Be certain that the
snap ring is properly fully and properly seated in the
groove.(6) If the original clutch plate and clutch pulley
are to be reused, reinstall the original shim(s) on the
compressor shaft against the shoulder. If a new
clutch plate and/or clutch pulley are being used,
install a trial stack of shims 1.0 mm (0.040 in.) thick
on the compressor shaft against the shoulder.
(7) Install the clutch plate onto the compressor
shaft.
(8) Install and tighten the compressor shaft bolt. If
necessary, a band-type oil filter wrench or a strap
wrench can be placed around the clutch plate to aid
in bolt tightening. Tighten the bolt to 17.5 N´m (155
in. lbs.).
NOTE: The shims may compress after tightening
the shaft bolt. Check the air gap in four or more
places to verify the air gap is still correct. Spin the
pulley before performing a final check of the air
gap.
(9) If a new clutch plate and/or clutch pulley are
being installed, the air gap between the clutch plate
and clutch pulley must be checked (Refer to 24 -
HEATING & AIR CONDITIONING/CONTROLS/A/C
COMPRESSOR CLUTCH - STANDARD PROCE-
DURE).
(10) Engage the retainer on the engine wire har-
ness compressor clutch coil take out with the bracket

BLOWER MOTOR RESISTOR
BLOCK
DESCRIPTION
This temperature control system uses a blower
motor resistor. The blower motor resistor is mounted
to the top of ventilation housing located in the engine
compartment. The blower motor resistor can be
accessed for service without removing any other com-
ponents.
OPERATION
The blower motor resistor block has multiple resis-
tor wires. Each resistor wire changes the resistance
in the blower motor current path to change the
blower motor speed. The blower motor switch directs
the current through the correct resistor wire to
obtain the selected speed.With the blower motor switch in the lowest speed
position, voltage for the motor is applied through all
of the resistor wires. Each higher speed selected with
the blower motor switch applies the blower motor
current path through fewer of the resistor wires,
increasing the blower motor speed. When the blower
motor switch is in the highest speed position, the
blower motor resistor is bypassed and the blower
motor circuit receives a direct path to battery volt-
age.
The blower motor resistor block cannot be repaired
and, if faulty or damaged, it must be replaced.

INJURY.
(1) Disconnect and isolate the battery negative
cable.
(2) Unplug the wire harness connector from the
blower motor resistor block.
(3) Check for continuity between each of the
blower motor switch input terminals of the resistor
and the resistor output terminal. In each case there
should be continuity. If OK, repair the wire harness
circuits between the blower motor switch and the
blower motor resistor or blower motor as required. If
not OK, replace the faulty blower motor resistor.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Depress resistor block locking tab and remove

Fig. 11 Ambient Temperature Sensor
1 - AMBIENT TEMPERATURE SENSOR
2 - FRONT FASCIA
24 - 16 CONTROLS - FRONTVA
AMBIENT TEMPERATURE SENSOR (Continued)

The rear evaporator temperature sensor consists of
a probe and a switch unit. The probe, which is a Neg-
ative Temperature Coefficient (NTC) thermistor in a
capillary tube, is inserted between the rear evapora-
tor coil fins to monitor evaporator temperature. The
switch unit contains internal control logic that mon-
itors the input from the probe in order to switch an
internal transistor that controls the output signal to
the rear A/C control module.
OPERATION
When the rear evaporator temperature sensor sees
a temperature input below about 1.6É C (35É F), it
signals the rear A/C control module to cycle the rear
A/C solenoid valve closed. When the temperature
input reaches above about 3.9É C (39É F), the switch
signals the control module to cycle the valve open.
The rear evaporator temperature sensor can be
accessed for service by removing the air inlet grate
from the rear evaporator housing. The rear evapora-
tor temperature sensor cannot be adjusted or
repaired. If faulty or damaged, the sensor must be
replaced.
DIAGNOSIS AND TESTING
Before testing the rear evaporator temperature
sensor, verify that the front A/C system is operating
correctly by performing the ATC Function Test using
the DRBIIItscan tool. Use a volt/ohmmeter to test
the sensor. For circuit descriptions and diagrams,
refer to the appropriate wiring information. The wir-
ing information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.
(1) Turn the ignition switch and the front A/C
switch to the On position. Place the rear blower
motor switch in either low or high speed position.
Check for voltage to the rear evaporator relay from
the rear evaporator temperature sensor. If OK, go to
Step 2. If not OK, repair the open or shorted evapo-
rator temperature sensor circuit as required.
(2) With the ambient temperature between 20 to
30É C (68 to 90É F), start the engine and run the rear
air conditioning system. The rear A/C solenoid valve
should cycle open and closed. Use a voltmeter con-
nected to the output side of the sensor for this check.
If the A/C solenoid valve fails to cycle in these tem-
peratures, replace the faulty rear evaporator temper-
ature sensor.
NOTE: If the ambient temperature is above 32É C
(90É F) the rear A/C solenoid valve may not cycle
due to the high heat load. This condition is normal.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the air inlet grate from the rear evap-
orator housing (Fig. 6).
(3) Disconnect the two wire harness connectors
from the rear evaporator temperature sensor.
(4) Remove the sensor probe from the rear evapo-
rator.
(5) Remove the two sensor retaining screws and
remove the sensor from the vehicle.
INSTALLATION
(1) Install the rear evaporator temperature sensor
and the two sensor retaining screws. Tighten the
screws to 2 N´m (17 in. lbs.).
(2) Install the sensor probe into the rear evapora-
tor.
(3) Connect the two wire harness connectors to the
rear evaporator temperature sensor.
(4) Install the air inlet grate onto the rear evapo-
rator housing.

SOLENOID VALVE
DESCRIPTION
The rear A/C solenoid valve is a two-position elec-
trically operated shut-off valve, which is used to con-
trol refrigerant flow to the rear A/C evaporator from
the A/C compressor. The solenoid valve is located in
the rear A/C evaporator housing and is attached by a
bracket.
OPERATION
The solenoid valve is used by the rear A/C control
module to control rear A/C output temperature and
to prevent evaporator freezing. Evaporator tempera-
ture is controlled by cycling the solenoid valve open
and closed, thereby controlling refrigerant flow to the
rear evaporator. The normally closed valve only
allows refrigerant to flow through it when power is
supplied to the solenoid by the rear A/C control mod-
ule.
DIAGNOSIS AND TESTING
For circuit descriptions and diagrams, refer to Air
Conditioning/Heater in Group 8W - Wiring Diagrams.
NOTE: Prior to performing the following checks,
verify that the front A/C system is operating prop-
erly.
(1) With the engine running, the front A/C switch
in the On position and the rear A/C blower switch in
the Off position, check that the rear evaporator is not
colder than the ambient temperature. If the evapora-
tor temperature is colder than the ambient tempera-
ture, the solenoid is allowing refrigerant to flow
through the rear evaporator when in the closed posi-
tion. If OK, go to Step 2. If not OK, replace the rear
A/C solenoid valve (Refer to 24 - HEATING & AIR
CONDITIONING/CONTROLS/SOLENOID - REMOV-
AL).
(2) With the ignition switch in the Off position and
the rear A/C solenoid valve wire harness discon-
nected, check for continuity between the two solenoid
valve terminals. If OK, go to Step 3. If not OK,
replace the solenoid valve (Refer to 24 - HEATING &
AIR CONDITIONING/CONTROLS/SOLENOID -
REMOVAL).
(3) With the ignition switch in the Off position and
the rear A/C solenoid valve wire harness discon-
nected, check the solenoid valve ground circuits for a
good ground at all times. If OK, go to Step 4. If not
OK, repair the open circuit to ground as required.(4) With the ignition switch and the front A/C
switch in the On position and the rear A/C solenoid
valve wire harness disconnected, check the harness
for battery power at terminal 2. If OK, replace the
solenoid valve (Refer to 24 - HEATING & AIR CON-
DITIONING/CONTROLS/SOLENOID - REMOVAL).
If not OK, test the A/C control module as required
(Refer to 24 - HEATING & AIR CONDITIONING/
CONTROLS/POWER MODULE - DIAGNOSIS AND
