Rear Wiper

When the front wiper relay (C39-6) receives a feed from the wash/wipe switch (C278-2), it outputs a feed (C39-2) back to the wash/wipe switch (C278-4) on a yellow/light green wire. Power flows across the wash/wipe switch (C278-1) and onto the wiper motor (C30-3), which operates at slow speed. When the washer switch is released, the relay will operate the wipers for a further 3 cycles. Once this has been completed, feed to the wash/wipe switch is cut by the relay and the park circuit is initiated.

Rear Wiper

The rear wiper switch (C1197-1) is supplied a feed by fuse 17 of the passenger compartment fuse box (C581-14) on a green wire. When the switch is in the ’on’ position (C1194-1), power is fed to the rear screen wiper motor (C388-2) on a red/light green then brown/light green wire. The wiper motor is earthed (C388-1) on a black wire.

Rear Park Circuit

Positioning the wiper switch to the ’off’ position cuts power to the rear wiper motor on the red/light green then brown/light green wire. The park circuit operates to return the wiper to its park position. The park switch (C1105-2) is integral to the wiper motor. It receives a feed from fuse 17 (C581-14) of the passenger compartment fuse box 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 switch (C1105-1) to the wiper switch (C1195-1) on a brown/light green wire. Power flows across the wiper switch (C1194-1) back to the wiper motor (C388-2) on a red/light green then brown/light green wire. The wiper motor is earthed (C388-1) on a black wire.

Rear Wash

The rear washer switch (C1197-1) is supplied a feed by fuse 17 of the passenger compartment fuse box (C581-14) on a green wire. When the switch is depressed power is fed (C1196-1) to the rear screen washer pump (C21-2) on a black/light green wire. The washer pump is earthed (C21-1) on a black wire. The rear screen wash does not operate the rear wiper.
