16 W wiper motor--
Parking switch adjustment
The parking switch of this motor is provided with
an adjustment to allow for different angles of park.
When replacing a drive gear assembly it may be
necessary to re-adjust the parking switch to suit
the new assembly. Failure to do this may result in
one of the following faults:
1.
With the wiper switch in the intermittent
position and the blades parked on the screen, moving
the switch to the off position does not cause the
blades to move to the off screen position.
2.
When moving the wiper switch from off to
intermittent, there is an
8 to 10 second delay before
the wiper motor operates.
If a new gear assembly has been fitted and the
wiper motor exhibits one of the above faults the
relevant following procedure should be adopted.

clamp from the wiper motor. Care must be taken to
ensure that the tube is not completely disconnected
otherwise the drive rack may become bent.
2.

accessible
(see Fig. 12177). Tighten the rack tube
nut. This will allow the motor to be operated and

switch securing screws and move the parking switch
fully inwards towards the gearwheel. Select
intermittent wipe, and once the blades have moved,
select off. The motor will not reverse and park.
4.
Carefully move the limit switch outwards to a
position where the motor will reverse and move the
blades to the correct parking position. Scribe a line
