WIPERS AND WASHERS 3 DESCRIPTION AND OPERATION Although windscreen wiper functionality remains the same, the mechanical architecture has undergone significant changes. The body structure has undergone some minor changes to house the revised wiper linkage. A modified wiper motor is introduced which is balanced to reduce operation noise. The brush plate is fitted with capacitors to reduce radio interference and a thermal cut-out is introduced to prevent motor burnout. The motor also contains a new park switch which also reduces operation noise. A common motor is now used on both LHD and RHD variants. The motor is repositioned on the bulkhead which allows a straighter drive cable run. The straighter run reduces load on the cable allowing a stiffer cable to be used. The stiffer cable and the incorporation of a reduced friction material reduces torsion wind-up of the cable and results in smoother wiper operation and a reduction of blade over travel. New, larger wheel boxes are fitted in an inverted position from the previous installation. The bulkhead mounting holes are larger with flats for positive location of the wheel box spindle. The wheel boxes now feature a 40 tooth gear ratio in lieu of a 32 tooth gear. This reduces backlash and load and further reduces blade over travel. The wheel box casings are secured with locknuts. The wheel box spindles now have a splined DIN taper fitting for the new wiper arms which are secured on the spindle with an M8 nut. The taper improves arm retention. A new grease is introduced which improves wiper operation at very low temperatures.
84WIPERS AND WASHERS 4 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.
