HEATER AND A/C OPERATION
HEATERÐXJ
A blend-air heating system is used in XJ vehicles.
The temperature of heated air is controlled by regu-
lating the quantity of air flow through the heater
core. This is accomplished by blending outside air
with heated air from the heater core to obtain the de-
sired discharge temperature. A temperature control
lever on the heater control determines air flow
through the heater core. The lever uses a cable to op-erate the blend-air door. This door controls air flow
through the core. Vacuum motors are used to actuate
and position the remaining door in the system.
On left hand drive (LHD) XJ vehicles a water valve
controls coolant flow to the heater core. The valve is
vacuum operated. When vacuum is applied, the valve
opens and coolant is directed through the heater core
and back to the engine. When the water valve is
closed (no vacuum applied) coolant flow bypasses the
heater core back to the engine.

WARNINGS, CAUTIONS AND SERVICE PRECAUTIONS
WARNINGS
WARNING: THE AIR CONDITIONING SYSTEM CON-
TAINS REFRIGERANT UNDER HIGH PRESSURE.
SEVERE PERSONAL INJURY MAY RESULT FROM
IMPROPER SERVICE PROCEDURES. REPAIRS
SHOULD ONLY BE PERFORMED BY QUALIFIED
SERVICE PERSONNEL.
WARNING: AVOID BREATHING A/C REFRIGERANT
AND LUBRICANT VAPOR OR MIST. EXPOSURE MAY
IRRITATE EYES, NOSE AND/OR THROAT. WEAR
EYE PROTECTION WHEN SERVICING THE AIR
CONDITIONING REFRIGERANT SYSTEM. SERIOUS
EYE INJURY CAN RESULT FROM EYE CONTACT
WITH REFRIGERANT. IF EYE CONTACT IS MADE,
SEEK MEDICAL ATTENTION IMMEDIATELY.
WARNING: DO NOT EXPOSE REFRIGERANT TO
OPEN FLAME. POISONOUS GAS IS CREATED
WHEN REFRIGERANT IS BURNED. AN ELEC-
TRONIC TYPE LEAK DETECTOR IS RECOM-
MENDED.
WARNING: IF ACCIDENTAL SYSTEM DISCHARGE
OCCURS, VENTILATE THE WORK AREA BEFORE
RESUMING SERVICE. LARGE AMOUNTS OF RE-
FRIGERANT RELEASED IN A CLOSED WORK AREA
WILL DISPLACE THE OXYGEN AND CAUSE SUFFO-
CATION.
WARNING: THE EVAPORATION RATE OF (R-134A)
REFRIGERANT AT AVERAGE TEMPERATURE AND
ALTITUDE IS EXTREMELY HIGH. AS A RESULT,
ANYTHING THAT COMES IN CONTACT WITH THE
REFRIGERANT WILL FREEZE. ALWAYS PROTECT
SKIN OR DELICATE OBJECTS FROM DIRECT CON-
TACT WITH REFRIGERANT.
WARNING: R-134A SERVICE EQUIPMENT OR VEHI-
CLE A/C SYSTEM SHOULD NOT BE PRESSURE
TESTED OR LEAK TESTED WITH COMPRESSED
AIR. SOME MIXTURES OF AIR AND R-134A HAVE
BEEN SHOWN TO BE COMBUSTIBLE AT ELEVATED
PRESSURES. THESE MIXTURES ARE POTENTIALLY
DANGEROUS AND MAY RESULT IN FIRE OR EX-
PLOSION CAUSING INJURY OR PROPERTY DAM-
AGE.
CAUTIONS
CAUTION: Liquid refrigerant is corrosive to metal
surfaces. Follow the operating instructions supplied
with equipment being used.
CAUTION: DO NOT use R-12 equipment or parts on
the R-134a system. Damage to the system will re-
sult.
CAUTION: Never add R-12 to a system designed to
use R-134a. Damage to the system will result.
CAUTION: R-12 compressor oil can not be mixed
with the R-134a compressor oil. They ARE NOT
compatible.
CAUTION: Do not over charge refrigerant system.
This will cause excessive compressor head pres-
sure and can cause noise and system failure.
SERVICE PRECAUTIONS
Recover the refrigerant before opening any fitting
or connection. Open fittings with caution even after
the system has been discharged. Never open or
loosen a connection before recovering the refrigerant.
The A/C system must always be evacuated before
charging.
DO NOT open the refrigerant system or uncap a
replacement component until you are ready to service
the system. This will prevent contamination in the
system.
Before disconnecting a component clean the outside
of the fittings thoroughly to prevent contamination
entering the system.
Immediately after disconnecting a component from
the system, seal the open fittings with a cap or plug.
Before connecting an open fitting always install a
new seal/gasket. Coat the fitting and seal with clean
refrigerant oil before connecting.
When installing a refrigerant line avoid sharp
bends. Position the lines away from the exhaust or
any sharp edges which may chafe the line.
Tighten fittings only to the specified torque. The
aluminum fittings used in the A/C system will not
tolerate over tightening.
When disconnecting a fitting use a wrench on both
halves of the fitting. This will prevent twisting of the
refrigerant lines or tubes.
Refrigerant oil absorbs moisture from the atmo-
sphere if left uncapped. DO NOT open a container of

COMPRESSOR SERVICE
DESCRIPTION
The A/C system uses a Sanden SD7H15 compres-
sor. The compressor is a 7 piston design.
The clutch used on the compressor consists of 3 ba-
sic components: the pulley and bearing hub, clutch
plate and field coil (Fig. 1). The pulley and field coil
are attached to the front of the compressor with ta-
pered snap rings. The compressor has a splined shaft
and the clutch plate is retained on the shaft with a
self-locking nut.
