WIPERS AND WASHERS

DESCRIPTION AND OPERATION

84-15

The rear wiper motor and control module assembly is located in the upper tail door, behind a trim panel. The assembly 
is secured to a bracket on the upper tail door with three, Torx head screws. Rubber bushes isolate the motor assembly 
from the bracket, which help reduce the transmission of motor operating noise to the tail door.

The assembly comprises the motor, mounting bracket and control module. The motor is located on a worm drive 
gearbox mechanism which converts the rotary motion of the motor output spindle into the required arc for the rear 
wiper blade. The control module is integral with the motor and has two plug sockets which accept two multiplugs from 
the harness. One multiplug has 2.5 mm diameter wires. Two of the wires supply permanent battery feed and ground 
connections for the motor and control module. The third wire in this plug supplies a power supply to the rear washer 
pump. The second multiplug has 0.35 mm diameter wires and carries signal data from the wash/wipe control stalk 
switch and the LCM and also a power input from the passenger compartment fusebox.

The rear washer feed hose is located at the rear of the motor spindle. The hose is connected to a 90

°

 connector 

allowing the washer fluid to flow through the centre of the motor spindle. An NRV is located in the hose, near the 
motor, and prevents fluid returning to the reservoir.

The motor spindle is a conventional design with a taper spline location for the wiper arm and a threaded shank to 
secure the arm to the spindle.

Wiper Arm
The wiper arm is similar in design to the front wiper arms. The arm attachment hole has tapered splines which mate 
with the splines on the wiper spindle. The arm is secured to the wiper motor spindle with a spring washer and nut. The 
wiper arm has a pivot point, close to the spindle attachment. A tension spring is connected to the wiper arm on each 
side of the pivot point and applies pressure to maintain the wiper blade in contact with the windscreen.

The wiper blade is attached to the wiper arm with a clip that allows the blade to pivot. The blade comprises a number 
of levers and yokes to which the rubber wiper blade is attached. The levers and yokes ensure that the pressure 
applied by the arm tension spring is distributed evenly along the full length of the blade and also allow the blade to 
adjust to the curvature and contour of the windscreen.

A plastic cap located on the arm pivot point, covers the spindle attachment nut. The cap also contains two, adjustable 
ball jets, which direct washer fluid onto the tail door window. The cap, when installed, connects with the hollow motor 
spindle, through which the washer fluid flows to the jets.
