Wipers And Washers

Windscreen Wiper/Washer Switch Fig. 1:

The single windscreen wiper blade is controlled by a windscreen wiper/washer switch located on the right-hand side of the steering column switch gear (see Fig. 1).

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 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 neck is a serviceable filter.

The screen wash jets with independently adjustable nozzles 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.

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 power wash jet is protected by a cover supplied with an integral cover-to-bumper seal. The cover snap fixes into the bumper.
