DESCRIPTION
An automatic temperature control (ATC) single
zone type heating-A/C system is standard equipment
on this model.
To maintain the performance level of the heating,
ventilation and air conditioning (HVAC) system, the
engine cooling system must be properly maintained.
The use of a bug screen is not recommended. Any
obstructions in front of the radiator or A/C condenser
will reduce the performance of the A/C and engine
cooling systems.
The engine cooling system includes the radiator,
thermostat, radiator hoses and the engine coolant
pump. Refer to 7 - Cooling for more information
before opening or attempting any service to the
engine cooling system.
All vehicles are equipped with a common ventila-
tion housing (Fig. 1) located in the engine compart-
ment which includes:
²Blower motor
²Blower motor resistor block
²Recirculation door and actuator
All vehicles are also equipped with a common
heater housing (Fig. 2) mounted under the instru-
ment panel which includes:
²Heater core
²Evaporator core
²Evaporator temperature sensor
²Expansion valve
²Air outlet temperature sensor
²Mode doors

(4) With the A/C compressor clutch engaged, duct
temperature should not be less than 2É C (35É F) or
more than 12É C (54É F). The compressor clutch may
cycle, depending upon the ambient temperature and
humidity. If the clutch cycles, use the readings
obtained before the clutch disengaged.
(5) If the A/C compressor clutch has not cycled off
and the duct temperature is less than 2É C (35É F),
check the evaporator temperature sensor and circuitby performing the ATC Function Test (Refer to 24 -
HEATING & AIR CONDITIONING - DIAGNOSIS
AND TESTING - ATC FUNCTION TEST).
(6) If the air outlet temperature fails to meet the
specifications, refer to the A/C System Diagnosis
chart.
A/C SYSTEM DIAGNOSIS
Condition Possible Causes Correction
Rapid A/C compressor clutch
cycling (ten or more cycles
per minute).Very low refrigerant system
charge.See Refrigerant System Leaks in this group.
Test the refrigerant system for leaks. Repair,
evacuate and charge the refrigerant system, if
required.
Equal pressures, but the
compressor clutch does not
engage.1. No refrigerant in the refrig-
erant system.1. See Refrigerant System Leaks in this
group. Test the refrigerant system for leaks.
Repair, evacuate and charge the refrigerant
system, if required.
2. Faulty fuse. 2. Check the fuses in the Power distribution
block and junction block. Repair the shorted
circuit or component and replace the fuses, if
required. Refer to Group 8.
3. Faulty A/C compressor
clutch coil.3. See A/C Compressor Clutch Coil in this
group. Test the compressor clutch coil and
replace, if required.
4. Improperly installed or faulty
evaporator temperature sensor.4. See Evaporator Temperature Sensor in this
group. Test the sensor and replace, if re-
quired.
5. Faulty A/C pressure trans-
ducer.5. See A/C Pressure Transducer in this
group. Test the sensor and replace, if re-
quired.
6. Faulty engine Control Mod-
ule (ECM).6. Refer to Group 9 - Engine Electrical Diag-
nostics for testing of the ECM. Test the ECM
and replace, if required.
Normal pressures, but A/C
Performance Test air temper-
atures at center panel outlet
are too high.1. Excessive refrigerant oil in
system.1. See Refrigerant Oil Level in this group.
Recover the refrigerant from the refrigerant
system and inspect the refrigerant oil content.
Restore the refrigerant oil to the proper level,
if required.
2. Blend door cable improperly
installed or faulty.2. See Mode Door Cables in this group. In-
spect the cable for proper operation and re-
place, if required.
3. Blend-air door(s) inoperative
or sealing improperly.3. See HVAC Housing in this group. Inspect
the blend-air door(s) for proper operation and
sealing. Repair if required.

NOTE: While holding the A/C-heater control in the
installation position, verify that the control cables
are not twisted.
(4) Turn the mode control knob on the A/C-heater
control to the nine-o-clock position.
(5) Turn the upper mode door lever counter-clock-
wise until it reaches its stop and install the cable
into the retainer in this position (arrow).
(6) Turn the lower mode door lever clockwise until
it reaches its stop and install the cable into the
retainer in this position (arrow).
(7) Operate the mode control and verify that the
mode door cables are properly adjusted.
(8) Install the A/C-heater control and the two
retaining screws. Tighten the screws to 2 N´m (17 in.
lbs.).
(9) Install the center bezel onto the instrument
panel (Refer to 23 - BODY/INSTRUMENT PANEL/
INSTRUMENT PANEL CENTER BEZEL - INSTAL-
LATION).
(10) Reconnect the negative battery cable.
RECIRCULATION DOOR ACTU-
ATOR
DESCRIPTION
This vehicle uses a two-position vacuum operated
recirculation door actuator to move the recirculation
door (Fig. 23). Vacuum supply to the recirculation
door actuator is controlled by an integral electronic
control solenoid. The recirculation door actuator ismounted on the outboard side of the ventilation
housing above the blower motor in the engine com-
partment.
OPERATION
The recirculation door actuator uses engine vac-
uum, which is controlled by an integral electrical
solenoid. The electrical solenoid is connected to the
A/C-heater control through the vehicle electrical sys-
tem by a dedicated two-wire lead and connector. The
output shaft of the recirculation door actuator is
keyed to a pivot shaft, which is keyed to the recircu-
lation door shaft. The recirculation door actuator can
move the recirculation door in two directions.
The recirculation door actuator is controlled by an
electrical switch that is integral to the A/C-heater
control. When the rotary-type mode control is moved
to the recirculation position, a signal is sent to the
electrical solenoid within the recirculation door
actuator. This signal causes the solenoid to open a
port to engine vacuum which pulls the output shaft
into the actuator, which moves the recirculation-air
door. The actuator is spring loaded so the door moves
to the fresh-air position when no vacuum is supplied
through the electrical solenoid.
The recirculation door actuator can be diagnosed
by performing the ATC Function Test using a
DRBIIItscan tool. Refer to Body Diagnostic Proce-
dures.
The recirculation door actuator cannot be repaired
and, if faulty or damaged, it must be replaced.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
