Wiper Motor
The rear wiper and washers operation is controlled by the CJB, via the rear wiper relay, which is located in the LH rear 'D'
post.
The rear wiper motor is located in the upper tail gate, behind a trim panel. The assembly is secured to the body of the
upper tail gate with three M6 nuts. Bushes isolate the motor assembly from the body, which help reduce the transmission
of motor operating noise to the tail gate.
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 feed hose, for the separate rear washer jet, is located at the rear of the motor spindle. The hose is connected to a 90
degrees connector allowing the washer fluid to flow through the centre of the motor spindle. A Non-Return Valve (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.
