Rearscreen wash/wipe

REARSCREEN WASH/WIPE

The rear window wiper and pump are controlled by the right lever on the stalk unit, which comprises two additional switches: one is a ring switch for controlling the rear window and and the other switch controls the pump. The rear window wiper motor (56) comprises a relay and a switch, constituting the control/reset circuit for the window wiper arm.

When the ring switch (I) located on the lever on the stalk unit (4) is turned, a terminal of the control relay is connected directly to earth by the C cable, providing a continuous supply to the motor.

WINDSCREEN WIPER

The windscreen wiper system is of the two-speed type plus intermittent function.

The right lever on the stalk unit (M) operates the windscreen washer pump and at the same time activates an automatic wiping cycle.

The system comprises:

Windscreen wiper motor (18)

A container is mounted on the motor body, which holds the switching circuit. This consists of a relay and a switch for the automatic return of the arms to the rest position.

Right lever on stalk unit (4)

The right lever on the stalk unit controls the windscreen wiper in intermittent or continuous mode and the windscreen washer pump, in accordance with the following logic:

• When the right lever is moved downwards one click, it activates the switch (M), which switches on the intermittent operation of the windscreen wiper at approximately 15 wipes per minute.
• When the switch (M) is turned two clicks (position 35), intermittent operation at about 35 wipes per minute is selected.

Its operation remains the same as that described above, except that the pause time between wipes becomes slightly over 2 seconds.

• When the switch (M) is turned three clicks (position 45), intermittent operation at 45 wipes per minute is selected.

If from the STOP position, the lever is pushed upwards and held in this position, continuous operation of the windscreen wiper is still selected, but with the lever in an unstable position.

In other words, the windscreen wiper operates for as long as the lever is held in this position, and it stops as soon as the lever is released.
