Windscreen washers description (Wipers & washers)

WINDSCREEN WASHERS DESCRIPTION

The windscreen washers are operated from the wash/wipe stalk located on the right hand side of the steering column. Operation of the windscreen washers will also operate the windscreen wipers.

If the wash/wipe stalk is pulled quickly and released, the washers will operate and the wipers will operate at slow speed for one cycle. If the stalk is pulled and held, the washers will operate and the wipers will operate at slow speed for as long as the switch is operated. When the stalk is released, the washers will stop but the wipers will continue for several cycles before stopping.

Two washer jets are located on the top surface of the bonnet. Each jet contains two adjustable jets which can be moved to obtain the correct coverage of the windscreen. The two jets are connected in series to a flexible pipe which is routed in the electrical harness to a washer reservoir. The reservoir is located inside the right hand wheel arch behind the wheel arch liner. A non-return valve is located in the feed pipe to the windscreen washer jets to prevent washer fluid siphoning back to the reservoir.

The reservoir is moulded from plastic and has a capacity of approximately 4.0 litres (7 pints). The reservoir has two ports which allow for the attachment of two washer pumps. The flexible pipe from the windscreen washer jets is connected to the forward of the two electric washer pumps. The reservoir has a filler tube which protrudes into the engine compartment. The tube is sealed by a removable cap. A filter is located in the neck of the filler tube and prevents the ingress of particulate matter when replenishing the reservoir. The filter can be removed for cleaning.

REAR SCREEN WASHER DESCRIPTION

The rear washer is operated from a non-latching push switch located on the fascia to the right of the instrument pack. Operation of the rear washer switch operates the washer and the rear wiper for as long as the switch is depressed. When the switch is released the rear wiper operates for five cycles before stopping.

The rear washer uses the same reservoir as the windscreen washers. A second electric washer pump is fitted to the reservoir and supplies washer fluid, via a pipe located in the wiring harness, to a single washer jet which is fitted in the rear wiper arm. The jet has four jets which direct washer fluid to each side of the wiper blade. A non-return valve is located in the feed pipe to the rear screen washer jet to prevent washer fluid siphoning back to the reservoir.
