System Overview
The climate control system provides filtered air to
the cabin from a fully automatic, dual zone,
temperature controlled system. Driver and front
passenger have independent control of the
temperature of the air for their individual
comfort. The system regulates the volume of
airflow from the vents of the instrument panel,
rear seat panel, front and rear floor ducts, front
screen defroster and side windows. It will
automatically select between fresh and
recirculated air to assist rapid cooling of the
interior.
Operation of the heated front screen or heated
wiper park area and rear window heater is
controlled from the climate control panel. Door
mirror heaters are automatically switched on
when the heated rear window is switched on. As
with current vehicles, the outside air temperature
can be displayed in either Celsius or Fahrenheit.
The system can be switched ON by pressing any
button, except OFF.
When ÔAUTOÕ is selected, the driverÕs and front
passengerÕs air temperature, fan speed and air
distribution are automatically controlled to give

JAGUARS-TYPEClimate Control
64Control Panel
The control panel is a combined unit
incorporating the air conditioning control module
(A/CCM).
Heater/Evaporator and Blower
A single blower, heater and evaporator are fitted
to the passenger side of the vehicle behind the
fascia. Air intake is from the passenger side via
leaf screen slots (see page 16). A particle filter is
mounted forward of the bulkhead in a rain/water
collector box. Mounting of the heater/evaporator
unit and blower assembly is by three bulkhead
fixings and one locator pin.
Condensate drainage is integral with the
heater/evaporator unit and therefore has no
separate drain tubes. The heater matrix is a dual
heater unit with three heater pipes, two inlets of
16mm diameter and one outlet of 19mm
diameter.
D.412.217
Underbonnet Components
Both V6 and V8 engine configurations include a
water valve controlled heating (dual) system and
the valve is mounted behind the right-hand side
headlamp. The V8 engine system, as with current
cars, has a water pump to supplement idle water
flow through the heater and this is mounted on
the right-hand side of the cooling pack. The pump
is held in a mounting rubber, which is pushed
over two pillars on the rear of the fan shroud and
held with two screws.
Condenser
The black-painted aluminium condenser is located
to the front of the combi-cooler and mounts to its
end tanks. The condenser end tubes push into two
grommets, which are in turn held in two steel
brackets, screwed to the radiator end tanks. The
bottom of the condenser is screwed directly into
the radiator tanks. A radiator cooling duct clips
onto the condenser end tanks and also pushes
onto the lower radiator channel. The duct ensures
that all available airflow is directed through the
cooling module.

67 Pipework
The suction hose and liquid line are a one-piece
assembly. A single screw connects them to the air
conditioning unit manifold at the bulkhead. A
further screw fixing and push-in clip secures them
at the side of the engine bay. The liquid line fixed
to the cooling module then joins with a block
fitting and the suction hose connects with a quick
connect fitting and routes across the underneath
of the cooling module to the compressor. The
compressor suction and discharge hoses are also a
one piece assembly.
A pressure transducer is fitted to the discharge
hose as it connects to the rear of the condenser.
The high side charge port is situated on the
manifold connecting to the receiver drier whilst
the low side is adjacent to the compressor behind
the LH front wheel.
The compressor is a 9Occ scroll, which is variable
from 100% to 30%. Compressor is standard
specification to all vehicles although package
makes them unique to V6 and V8.
Air Distribution
Air distribution is as follows:
¥ Defrost duct integral with the fascia.
¥ Face vents, plenum, manifold, centre face
duct, side face duct, side window demist duct
are all sub-assembled into the fascia.
¥ Driver and front seat passenger foot ducts are
installed in the fascia after it has been fitted
to the vehicle.
¥ Rear foot ducts are fitted to the underframe.
¥ Rear face duct fitted to transmission tunnel.
¥ Rear face vent fitted to console.
¥ Extractor boxes fitted in rear quarter panels.
All flaps are electric servo controlled and
comprise:
¥ Fresh/recirculation - heater/evaporator unit.
¥ Cold air bypass - heater/evaporator unit.
¥ Foot flap - mounted on plenum.
¥ Defrost flap - mounted on plenum.
¥ Face flap - mounted on plenum.
Sensors, for operation of the system, are:
¥ Ambient temperature sensor - located behind
the lower front grille.
¥ Solar sensor - fitted to the top centre of the
fascia at the defrost grille
¥ In-car sensor - aspirated from the plenum
venturi sensor mounted inboard of the
steering column.¥ Two heater air outlet sensors
¥ One evaporator air outlet sensor
Servicing
Routine servicing consists of particle filter
replacement.
Replaceable items on the climate control system
are:
¥ Servo complete with linkages
¥ Sensors
¥ Evaporator and seals
¥ Heater core and seals
¥ Blower motor
¥ Impeller/blower motor wheel
¥ Hoses
¥ Registers/vents
¥ Ducts, except the defrost
¥ Defrost and side window demist grilles
¥ Control unit
¥ Compressor
¥ Water pump
¥ Water valve
¥ Receiver/drier
¥ Condenser
There are no panel diagnostics but PDU facility is
available with extensive capability, similar to
current XJ and XK Series.
System refrigerant is R134a. Vehicle charge weight
is 800 gms and charging is through the high side
charge port only.
Oil type is WSH-MIC231-B and refill quantity is
180 cc -220 cc.
Special tools are hose clamp pliers and air-
conditioning hoses spring lock de-coupler.
General information
Ensure that the grille at the base of the windshield
is kept clear of leaves, snow or other obstructions.
A solar sensor is mounted on top of the fascia, in
the centre of the defrost grille, and this should not
be covered.
The air conditioning system should be run briefly
at least once each week with a cold setting to
prevent the seals from drying out with subsequent
refrigerant leaks.
When the engine and vehicle interior are cold the
fan speed may be low until the engine has warmed
up, this avoids excessively cold air being blown
into the cabin.

74The SCP communication network will remain
operational even with severing of one of the bus
wires. Communications will also continue if one
of the bus wires is shorted to ground or battery
positive voltage (B+), or if some , but not all,
termination resistors are lost.
Unlike the SCP communication network, the
ISO 9141 communication network will not
function if the wire is shorted to ground or battery
positive voltage (B+). Also, if one of the modules
on the ISO 9141 network loses power or shorts
internally, communication to that module will fail.
Control Modules
The vehicle control module functions are
described briefly below (for further information
refer to the relevant sections throughout the
Guide).
