Windscreen washer and wiper operation (Wipers & washers)

WINDSCREEN WASHER AND WIPER OPERATION

Operation of the windscreen wipers and washers is controlled by the wash/wipe switch mounted on the stalk on the RH side of the steering column. The wiper switch may be rotated from the OFF position to selected positions; Intermittent, Normal or Fast wipe speeds. Single wipe is obtained by a downward movement of the stalk from the OFF position. The windscreen washer will operate when the stalk is pulled towards the steering wheel.

When any wiper function is selected, a 2 speed wiper motor (1) provides drive through a rotary link (2) to 2 wiper mechanisms (3) which convert the lateral motion of the links into the sweeping motion of the wiper arm (4) and blade (5).

The fast, normal and intermittent speeds, when selected, are controlled by the multi-function unit.

When the windscreen washer is operated, washer fluid is drawn by an electric pump (6), from the reservoir (7) located behind the front bumper on the RH side and is sprayed against the windscreen by jets (8). The wipers will continue to operate for a period of 6 seconds after the washer switch has been released.

Certain model derivatives are fitted with heated washer jets. The integral heaters are activated simultaneously with vehicle ignition, rising rapidly to a self-regulated temperature.

NOTE: It is still necessary to add a mixture of screenwash and water to the washer reservoir to prevent freezing in cold weather.
