Rear Wiper

When the delay unit (C303-6) receives a feed from the washer switch (C278-2), it outputs a feed (C303-2) to the wash/wipe switch (C278-4) on a yellow/light green wire. Power flows out through the wash/wipe switch (C278-1) and onto the wiper motor (C030-3), which operates at slow speed. When the washer switch is released, the delay unit will operate the wipers for a further 3 cycles. Once this has been completed, feed to the wash/wipe switch is cut by the delay unit and the park circuit is initiated.

Rear Wiper

The rear wiper switch (C918-1) is supplied by fuse 3 of the passenger compartment fuse box on a green wire. When the switch is in the "on" position (C915-1), power is fed to the rear screen wiper motor (C388-2) on a red/light green wire. The wiper motor (C388-1) is earthed on a black wire.

Park Circuit

Positioning the wiper switch to the "off" position cuts power to the wiper motor on the red/light green wire. The park circuit operates to return the wiper to its park position. The park switch (C079-2), integral to the wiper motor unit, receives a 12 volt supply from fuse 3 of the passenger compartment fuse box (C580-6) on a green wire. The park switch is closed with the wiper in any position except its park position

With the park switch closed, power flows across the park switch (C079-1) to the wiper switch (C916-1) on a brown/light green wire. Power flows through the wiper switch (C915-1) to the wiper motor (C388-2) on a red/light green wire. The wiper motor is earthed (C388-1) on a black wire.

Rear Wash

The rear wash switch (C918-1) is supplied by fuse 3 of the passenger compartment fuse box on a green wire. When the switch is closed (C917-1), power is fed to the rear screen washer pump (C021-2) on a black/light green wire. The washer pump (C021-1) is earthed on a black wire. The rear screen wash does not operate the rear wiper.
