15.6.1
The single windscreen wiper blade is controlled by a windscreen wiper/washer switch located on the right-hand side
of the steering column switchgear (see Fig.
1).
POWER WASH & SCREEN WASH/ WlPE
Windscreen Washers & Wipers, General Description
The windscreen wiper motor, part of the wiper motor
assembly operates at slow or fast speeds and drives the
lever assembly, a single arm and blade via a crank.
On
V12 engined vehicles the wiper motor assembly is
mounted to the front of the bulkhead with the motor
protruding into the plenum chamber, whilst on AJ16 engined vehicles the wiper motor assembly is mounted into
the same position, but with the motor protruding into the
engine compartment.
For wipe and wash operation
a mixture of water and special
'Jaguar Windscreen Fluid' is drawn from the PVC reservoir
assembly by
two electrically controlled pumps and is then
distributed via flexible feeder hoses interconnected using
'TEE' pieces to the screen wash jets and to heated power
wash jets (where fitted). The ends of power wash hoses are
fitted with 'quick
fit' fluid connectors.
The
two pumps, one for screen wash and one for headlamp
power wash are externally fitted to the reservoir located at
the front right
-hand side of the engine compartment.
Contained within the reservoirs pull-up neckis a serviceable
filter.
The screen wash jets with independently adjustable
eyeballs are mounted on the plenum chamber finisher and
the temperature of the fluid passing through the jets is
controlled from an ambient temperature sensor fitted near
the inlet of the right
-hand side air duct. Fig.
1
The
fluid temperature for each of the headlamp wipe wash operation is controlled by self regulating, heated power
wash jets mounted on to either side of the bumper.
Each powerwash jet is protected by
a cover supplied with an integral cover-to-bumperseal. The cover snap fixes into
the bumper.
15.6.2
This switch only operates with the ignition switch in position '11' and has the following functions:
windscreen Wiper and Washer Switch
Position 0 The wind screen wiper is switched 'OFF' and parked.
Position 1: Normal speed wiper operation is obtained by pushing the switch lever up one position.
Position 2: High speed wiper operation is obtained by pushing the switch lever fully up.
Position D: To obtain intermittent wiper operation the switch lever is pushed down and released.
The delay period will vary with vehicle speed. To cancel the function repeat the procedure.
15.6.2.1 Single Wipe Operation
To obtain a single sweep of the wiper blade, the lever is pulled towards the steering wheel and released.
W The intermittenmick wipe operations are both at slow speed and they are controlled by a Central Control
Module (CCM), which also controls the headlamp power wash operation.
Issue 1 August 1994 X300 VSM

15.6.2.2 Programmed Wash / Wipe Operation
The end of the switch lever must be pressed inwards for the windscreen wash and wipe operation. Wash / wipe con- tinues for as long as the lever is pressed.
When released, the windscreen wiper stops immediately and the wiper blades sweep for
a further three wipes.
On pressing the end of the switch lever inward and then releasing
it, the windscreen washers operate for approximately
two seconds before stopping, whilst the wiper blade continues for a further three wipes.
N&: If the end of the switch lever is pressed while the washer fluid warning light is illuminated, the windscreen
washers, but not the wiper blade continues to operate.
0
15.6.2.3 Headlamp Power Wash Operation (where fitfed)
The headlamp power wash operates only when the programmed washer/ wipe function is selected and the side lights
are 'ON'
The headlamp power wash does not operate if the windscreen washer reservoir fluid lever is low. This is indicated
by the washer fluid level warning light illuminating.
&&: The headlamp power wash only operates on the 1st and every 6th succeeding cycle of the programme wash /wipe switch, after the ignition switch has been turned to position '11'.

WARNING: FUME EXTRACTION EQUIPMENT MUST BE IN OPERATION WHEN SOLVENTS ARE USED E.G.
TRICHLOROETHANE, WHITE SPIRIT, SBPB, METHYLENE CHLORIDE, PERCHLORETHYLENE.
DO NOT SMOKE IN THE VICINITY OF VOLATILE DEGREASING AGENTS.
Adhere strictly to handling and safety instructions given on containers and labels. Keep oils and solvents away from
naked flames and other sources of ignition. Do not apply heat in an attempt to free seized nuts or fittings; as well as
causing damage to protective coatings, there is
a risk of damage from stray heat to electronic equipment and brake
lines. Do not leave tools, equipment, spilt oil etc. around or on work
area. Wear protective overalls and use barrier
cream when necessary.
0 A3.1.1 Used Engine Oils
Prolonged and repeated contact with mineral oil will result in the removal of natural oils from the skin, leading to dry- ness, irritation and dermatitis. In addition, used engine oil contains potentially harmful contaminants which may cause
skin cancer. Washing facilities and adequate means of skin protection should be provided.
A3.1.2 Health Protection Precautions
0 Avoid prolonged and repeated contact with oil; particularly used engine oils.
o Wear protective clothing, including impervious gloves where practicable
0 Do not put oily rags in pockets.
0 Avoid contaminating clothes, particularly underwear, with oil.
0 Overalls must be cleaned regularly. Discard unwashable clothing and footwear which is oil impregnated.
o First Aid treatment should be obtained immediately for open cuts or wounds.
0 Use barrier creams, applying before each work period, to enable easier removal of dirty oil / grease from the
skin.
0 Wash with soap and water to ensure that all oil is removed (skin cleaner and a nail brush will help). The use of
preparations containing lanolin will help to replace the natural skin oils which have been removed.
o Do not use petrol, kerosene, gas oil, thinners or solvents for washing skin.
0 If skin disorders develop, obtain medical advice immediately.
0 Where practicable, degrease components prior to handling.
0 Where there is a risk of fluids coming into contact with the eyes, eye protection should be worn, for example,
goggles or a face shield. An eye wash facility should be provided.
A3.1.3 Environmental Protection Precautions
A3.1 SAFETY PRECAUTIONS
Whenever possible, use a ramp or pit whilst working beneath a car, in preference to jacking. Position chocks at the
wheels as well as applying the handbrake. Never rely on a jack alone to support a car. Use axle stands, or blocks care- fully placed at the jacking points, to provide a rigid location. Checkthat any lifting equipment used has adequate capac- ity and is fully serviceable. Ensure that a suitable form of fire extinguisher is conveniently located.
When using
electrical tools and equipment, inspect the power lead for damage and check that it is properly earthed. Disconnect
the earth (grounded) terminal of the car battery. Do not disconnect any pipes of the air conditioning refrigeration sys-
tem unless you are trained and instructed to do so. A refrigerant is used which can cause blindness if allowed to come
into contact with the eyes. Ensure that adequate ventilation is provided when volatile degreasing agents are being
It is illegal to pour used oil on to the ground, down sewers or drains, or into water courses. The burning of used engine
oil in small space heaters or boilers is not recommended unless emission control equipment is fitted. Dispose of used
oil through authorized waste disposal contractors, to licensed waste disposal sites or to the waste oil reclamation trade.
If in doubt, contact the Local Authority for advice on disposal facilities.
