The stalk unit
H5
is supplied at
pin 3 of connector D from the ignition-operated line (INT/A) of
the relay
R1
protected by the fuse
F14
: both are
contained in the junction unit
B1
.
The rear wiper is activated by stalk switch
H5
via
a signal sent by pin 1 of connector D to rear wiper motor
N16
.
When operated, the windscreen washer switch
on the steering column switch unit
H5
sends two signals from
pin 8 and pin 9 of connector A, which reach the pump for operating
the windscreen washer
N22
directly. The motor is operated
upon a command from stalk switch
H5
in the opposite manner
to that described for the washer function (when the motor is operated
in reverse, it sends fluid to the back instead of to the front).
One of the two signals (pin 2 of connector
D of
H5
) is sent to electronic device inside rear wiper motor
N16
that controls the operation of the rear wiper in conjunction
with the rear washer.
The rear wiper motor
N16
is then
connected to earth. It consists of the actual geared motor, the
end of travel contacts and the electronic adjustment and control
device.
