DESCRIPTION AND OPERATION Washer The rear washer is operated by pressing the non-latching switch mounted on the RH side of the instrument pack. The washer will operate until the switch is released. The rear wiper will start operating at slow speed as soon as the washer switch is depressed, and will continue to operate at slow speed for approximately 6 seconds after the switch is released.
OPERATION Front General Feed from the positive battery terminal (C0192) is supplied to fusible link 3 of the engine compartment fuse box (C0632) on an R wire. Fusible link 3 (C0571) is connected to the ignition switch (C0028) by an N wire. When the ignition switch is turned to the 'ignition' position, current flows across the switch (C0028) to fuse 8 (C0588) on a G wire, and fuse 3 (C0588) on an NW wire. Both are located in the passenger compartment fuse box. Fuse 8 and fuse 3 (C0593) both provide an ignition feed to the front wiper relay contained within the Central Control Unit (CCU). The CCU (C0593) is earthed via the passenger compartment fuse box (C0587) on a B wire. Intermittent Wipe Fuse 3 of the passenger compartment fuse box (C0580) provides an ignition feed to the wiper switch (C0035) on an LG wire, and the variable wipe potentiometer (C0320) on a GY wire. When the wiper switch is moved to the intermittent wipe position, current flows across the switch (C0035) to the CCU (C0428) on a G wire. The variable wipe potentiometer has 5 pre-set positions. The potentiometer (C0320) is connected to the CCU (C0429) by a WK wire. The voltage supplied to the CCU by the potentiometer is dependent upon its position. The CCU is able to determine the amount of delay to apply to the wipers by measuring the voltage provided on the WK wire. When the CCU receives a feed from the intermittent wipe switch and the potentiometer, it provides an intermittent feed back to the wiper switch (C0035) on a LGK wire. The wiper switch (C0035) is connected to the wiper motor (C0030) by a ULG wire. Current flows across the motor slow speed windings and is earthed (C0030) on a B wire. Slow Wipe Fuse 3 of the passenger compartment fuse box (C0580) provides an ignition feed to the wiper switch (C0035) on a G wire. When the wiper switch is moved to the slow wipe position, current flows across the switch (C0035) to the wiper motor (C0040) on a ULG wire. Current flows across the motor slow speed windings and is earthed (C0030) on a B wire.
