Rear window wiper (5D)

Rear window wiper (5D)


When the ON/OFF button is moved from OFF to TIP (towards the steering wheel), the rear window wiper will start in intermittent mode and make one stroke every 8 seconds. This period is controlled by DICE and is not adjustable.

If the button on the end of the wiper stalk switch is depressed, the rear window washer will start and the wiper will operate continuously as long as the button is kept depressed. The rear window wiper performs 3 strokes after the rear window washer button has been released and then once more 8 seconds after the last stroke.

If the windscreen wipers are operating either intermittently or continuously and reverse gear is engaged, the rear window wiper will start in intermittent mode. The rear wiper is active until reverse gear is disengaged.

When the switch (61a) is made, +54 voltage will be applied to the intermittent wiper relay (83a) and the switch (61a) via fuse 4. Pin 19 on DICE (628) is supplied with voltage from switch pin 4. DICE pin 12 grounds the relay (83a) and the motor (62R) is supplied with power from pin 2.

There is a built-in mechanically controlled connector (31B) in the wiper motor that receives power, regardless of the switch's (61) position. As a result, the intermittent function only requires a start pulse from DICE to become active.

If the rear window wiper button is pressed, voltage will be applied to DICE pin 42 and the washer pump from pin 2 on the switch (61a). Voltage is applied to DICE pin 68 from pin 5 on the switch (61a). Pin 12 on DICE grounds pin 5 on the relay (83a), which closes. Voltage is fed from relay (83a) to the wiper motor (62R) pin 2. The relay (83a) is grounded for 5 seconds after the switch (61a) has been pressed. This is the equivalent of 3 strokes of the rear window wiper.
