2Disconnect the washer hose and withdraw
the nozzle.
Refitting
3To refit, reconnect the washer hose to the
nozzle, and push the nozzle into its locating
hole.
4The nozzles can be adjusted by inserting a
pin into the jet, and swivelling it to the
required position.
1991-on models
5The nozzles on all later models are fitted
with twin jets.
6On some later models, the nozzles are
heated; the circuit is fed through fuse 29 and
is live whenever the ignition is switched on.
Current is regulated by a Positive
Temperature Coefficient (PTC) resistor that
takes outside temperature into account.
38Windscreen wiper motor and
linkage - removal and refitting

Removal
1Disconnect the battery negative lead.
2Remove the wiper arms, as described in
Section 36.
3Remove the windscreen cowl panel, as

1Disconnect the battery negative lead.
Models without headlamp wash
Removal
2Disconnect the wiring from the washer
pump.
3Disconnect the washer fluid hose from the
pump. Be prepared for fluid spillage.

5Refitting is a reversal of removal.
Models with headlamp wash
Removal
6On models with headlamp wash, the
reservoir is in two sections, the upper section,
which can be removed from the engine
compartment, and the lower section, which
must be removed from under the wheel arch.
7Disconnect the wiring from the headlamp
wash non-return valve in the top of the
reservoir.
8Disconnect the washer fluid hoses from the
non-return valve. Be prepared for fluid spillage.
9Remove the screw securing the upper
section of the reservoir to the wing panel.
10Loosen the plastic collar securing the
upper section of the reservoir to the lower
section, then withdraw the upper section of
the reservoir from the engine compartment.
11To remove the lower section of the
reservoir, continue as follows.
12Apply the handbrake, then jack up the
front of the vehicle, and support on axle
stands (see “Jacking and Vehicle Support”)
positioned under the body side members.
13Remove the securing screws, and
withdraw the plastic cover from thebumper/front wing to expose the lower
section of the reservoir.
14Remove the horns, (Section 22).
15Remove the wheel arch liner, (Chapter 11).
16Disconnect the wiring and the fluid hoses
from the washer pump. Be prepared for fluid
spillage.
17Unscrew the bolts securing the

Removal
2Disconnect the wiring and the fluid hose
from the pump. Be prepared for fluid spillage.
3Pull the pump from the reservoir, being
prepared for fluid spillage if the reservoir still
contains fluid.
4Examine the condition of the sealing
grommet, and renew if necessary, and clean the
gauze filter at the end of the pump pick-up tube.
