13.2.1 Doors, Description
Doors are of welded, mild steel frames welded to the door panels; sponge rubber primary and secondary seals are
mounted on the doors. Internal insulation is provided by a foam water shedder attached to the door by press fitting and doublesided adhesive tape.
Front and rear door armrests are attached to supports riveted to each door frame; the attaching screws are fitted
with access covers. Upper and lower trim pads and a door pocket are attached to each of the doors by clips and screws. multi-plug connectors are used to provide a means of connecting the guard lamps, window lift switches and loud- speakers, external mirror and regulator (front doors only), which are housed within the doors.
Central locking is provided subject to market variations: Dead Locking for UK
/ Europe and Driver only unlock for N America. Door locks are eight disc, bayonet fixing, barrels with integral lock / unlock switches. Keys include ‘in-key’
transponders which are programmed to the vehicle via the Jaguar Diagnostic System also operate the engine immobi
- lisation system.
CAUTION: When removing the door panel water shedder, a foam membrane attached to each door panel by a com- bination of pressfitting (upper area) and bydouble-sided tape (bottom area), it is important that the shed- der is refitted correctly to maintain the water seal.
It is advisable not to disturb the bottom (taped) portion of the water shedder unless absolutely necessary
- it is possible to unclip the top of the shedder and bend it over to gain access to the inner panel.
If
it is necessary to disturb the bottom attachment, eg to remove the water shedder from the door panel,
the existing water shedder must be discarded and a new one fitted to ensure that the seal is maintained.
On refitting, the new water shedder should be pressed onto the door panel at the top and then the adhes- ive tape backing strip peeled off to enable the shedder to be pressed home at the bottom.

13.8 SEATING AND SEAT BELTS
13.8.1 Seating, Description
The front seats are available in a range of materials consisting of sculptured fabric / leather, leather, sports cloth / leather, embossed leather / leather and autolux. Both seats are available as 'manual', ie manually adjustable with elec- tric rise and fall, manual height adjustment headrests, 'power', ie 12-way electric adjustment, 'power with memory', ie memory controlled, 12-way electric adjustment of seat, steering column and exterior rear view mirrors and 'heated',
ie with integral heating.
Front seats are based on a non
-handed, one-piece frame which includes cushion and squab frames and seat adjuster
mechanisms. The seat switchpacks (powerseats) are fitted to the outboard side of driver and passenger seats; on 'man- ual'seats, the seat height adjustment switch is similarly located. Seat control modules SCMs are contained within the
seat assemblies. The seats are secured through four mounting points to the vehicle floor.
Rear seats are of the bench type with
full width removable cushion and individual seat squabs.
Electrical components installed on the heel board below the rear passenger seat are protected
by two covers secured
by two locating brackets on the floor and by two latches on the cover. The latches are released by pushing down on
the two recesses in the top edge of the cover.

8. AUTO selection display.
9. EXTERIOR temperature selection button. There are two modes:
a) Press and immediate release; provides timed display of four (4) seconds.
b) Press and hold for two (2) seconds; 'latches' the mode until operator over-ride.
10. A/C push-on / push-off button will either engage or disengage (as indicated by the state lamp) the refrigeration
system compressor. The state lamp is also used as a compressor speed fault indicator,see System protection, this
section.
11. AUTO push-on button and state lamp. When selected and the state lamp lit, the A/C mode is selected and control
of demand temperature, fans speed, and air distribution is automatic. AUTO is cancelled by selection of any 'dis- tribution' button, A/C off, or manual FANS SPEED.
12. DEFROST push
-on / push-off button and state lamp. When engaged, air is distributed to the screen at maximum
fans speed and the heated front screen elements (where fitted) are ener ized. The heated front screen is automati- cally timed for a six (6) minute cycle but may be cancelled by pressing tfe HEATED FRONT SCREEN button. Auto- matic temperature control is retained and the fans speed may be manually reduced. Deselection will return the
system to the previous state and selection of AUTO will resume automatic system control.
13. The push
-on / push-off (F) button with state lamp manually controls the HEATED FRONT SCREEN (where fitted).
This facility allows rapid screen de-icing using laminated electrical heating elements to supplement the hot air
defrost.
14. The push-on / push-off (R) button with state lamp manually controls the HEATED REAR SCREEN and door mirror
glass heating elements for a timed cycle of; screen twenty (20) minutes and mirrors eleven (1 1) minutes.
m: The state lamp will remain lit after the mirror timer has gone through its 11 minute cycle and will not go out
until either completion of the 20 minute screen cycle or manual override.
15. TEMPERATURE decrease button
in IoC or I0F steps.
16. TEMPERATURE increase button in
IoC or I0F steps.
w: Automatic temperature control operates over the range 17OC to 31OC (61OF to 90OF). Extreme limits selected
by items 15 and 16 ('Lo' and 'Hi') provide maximum cooling or heating at maximum fans speed.
17. FACE level manual distribution over
-ride push-on / push-off button and state lamp.
0 18. Bi LEVEL (foot and face) manual distribution over-ride push-on / push-off button and state lamp.
19. FOOT level manual distribution over
-ride push-on / push-off button and state lamp.
20. DEMIST (screen and foot) level manual distribution over
-ride push-on / push-off button and state lamp.
!Y&Q: Selection of AUTO will over-ride any manual setting and deselection of any manual distribution will revertthe
system to AUTO distribution.

14.10 FAULT DIAGNOSIS
14.10.1 Introduction
It is very important to positively identifythe area of concern before starting a rectification procedure. A little time spent
with your customer to identify the conditions under which a problem occurs will be beneficial. Relevant criteria are:
Weather conditions, ambient temperature, intermittent or continuous fault, airflow fault, temperature control fault, dis
- tribution fault and air inlet problem.
14.10.2 Functional Check
This simple 'first line check' will allow you to ascertain whether the system is operating within its design parameters,
without recourse to (JDE). Please carry out the following, in order.
0 Start engine and attain normal running temperature.
0 Presss AUTO to display selected temperature and illuminate AUTO & AJC state lamps.
0 Rotate FAN to increase or decrease lower speed, verify bar graph representation.
0 Operate AJC to toggle on or off. Because the compressor can be inhibited by the engine management system,
ensure that the engine temperature is normal and that the ambient is above 5O C.
0 Operate RECIRC, state lamp should be lit and the flap behind the blower grille open.
0 Operate distribution buttons in turn, verify correct air distribution and relevant state lamp.
0 Operate DEFROST, check max fans and air to front screen.
0 Cycle TEMPERATURE to 'Hi' and 'Lo' to verify demanded variations and display operation. Note that extremes
will provide max heat or cold independent of in-car temperature.
0 Operate EX to toggle between ambient and control temperatures.
0 Operate HFS and HRW to note timer and mirror operation.
0 Initiate System Self Test to check for, and extract, stored faults should any of the above not perform as stated.
14.10.3 System symptoms
There are five basic symptoms associated with air conditioning fault diagnosis. The following conditions are not in order of priority.
No Cooling
0 Is the electrical circuit to the compressor clutch functional?
0 Is the electrical circuit to the blower motor(s) functional?
0 Slack or broken compressor drive belt.
0 Compressor partially or completely seized.
0 Compressor shaft seal leak.
0 Compressor valve or piston damage (may be indicated by small variation between HIGH &LOW side pressures
relative to engine speed).
0 Broken refrigerant pipe (causing total loss of refrigerant).
0 Leak in system (causing total loss of refrigerant) - possible code 23.
0 Blocked filter in the receiver drier.
0 Evaporator sensor disconnected - possible code 13.
0 Pressure switch faulty - possible code 23.
