DESCRIPTION AND OPERATION REAR WIPER - FROM 02MY
1.Rear wiper relay
The rear wiper system is unchanged except for the addition of a wiper motor relay into the electrical circuit.
The new rear wiper relay is located in the tail door, below the wiper motor. The relay coil is energised by a feed
supplied from the rear wiper switch. When the relay contacts close, a feed is supplied via the ignition switch
(position II) and a fuse in the passenger compartment fuse box, through the relay contacts to the wiper motor.
