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.

68Heated wiper park or (where optionally fitted)
heated front screen.
With the engine running, due to the high current
draw, press to switch on the heated wiper park to
defrost the wiper park area, or where fitted, press
to switch on the heated front screen for rapid
defrost/demist.
Heated wiper park automatically operates in cold
weather, and may stay on continuously. It is
automatically switched on when ÔDEFROSTÕ is
selected. If manually selected, the heated wiper
park will automatically switch off after 10
minutes.
Heated front screen is automatically switched on
when ÔDEFROSTÕ is selected. It will automatically
switch off after 4 minutes. The heaters will switch
off, or not operate, if low battery voltage is
detected.
Heated Rear Screen
With the engine running due to the high current
draw, press to switch on the heated rear screen
for rapid defrost/demist. The rear screen heater
will be automatically switched off after 10
minutes.
In cold conditions, the heated rear screen
operates automatically. Selecting ÔDEFROSTÕ will
also turn the heated rear screen ON. The heaters
will switch off, or not operate, if low battery
voltage is detected.
Air Distribution
Air distribution is automatically controlled when
ÔAUTOÕ is selected. Manual control can be
achieved using the air distribution buttons.
Heat at Rest Feature (V8 engine vehicles
only)
Interior heating may be continued after the
engine has been switched off by turning the
ignition to position ÔIIÕ. The climate control system
will continue to provide heat to the vehicle
interior until the engine cools down. Excessive use
will cause a low battery voltage, which may
prevent the vehicle from being started.
Voice Activated Control
Some functions of the climate control system can
be operated with the Voice Activation System
(when fitted).
A full operating description is given in the Voice
Activation Handbook included with the vehicle
literature pack.

the clean power fuse to the front fusebox is
routed on the LH side of the vehicle and along
part of the main body wiring harness.
Harnesses
The vehicle harnesses plug directly into
components or component flying leads using
locking connectors. The main harness layout is

Fuses and Relays
Fuses
Fuse failure is identified by an inoperative circuit.
Two types of fuses are fitted in the fuseboxes, a
mini-type and a cartridge-type.
A special tool for removing and replacing the
mini-fuse is provided in the passenger
compartment fusebox, together with spare fuses.
If a spare fuse is used, replace it with a Jaguar
approved fuse of the same amperage rating.
Checking and Renewing a Blown Fuse
Make sure the new fuse is the correct rating
(amperage). Fuses are colour coded according to
the amperage and the rating is also marked on
each fuse.
WARNING:
Do not fit a fuse of a different amperage from
that removed. The electrical circuits may
become overloaded with the subsequent
possibility of a fire.
No attempt should be made to repair a fuse
that has blown. This may cause a fire hazard
or serious damage elsewhere in the
electrical circuit.
Fuse Boxes
There are three separate fuse boxes fitted to the
vehicle, each one containing fuses protecting a
different group of circuits.
They are located in:
¥ The engine compartment
(front power distribution box/fusebox)
¥ The passenger compartment
(primary junction box/fusebox)
¥ The luggage compartment
(rear power distribution box/fusebox)
Engine Compartment Fusebox
The fusebox is located in the engine compartment
on the RH side adjacent to the windshield wash
reservoir.
Caution:
When a fusebox lid is removed, take care to
protect the box from moisture, and refit the lid at
the earliest opportunity.
Remove the fusebox lid by pressing the retaining
lugs and lifting.
When refitting, press the fusebox lid in the area of
the retaining lugs until the lid engages.
