Removal
1Using a length of strong thin cord or fishing
line, break the adhesive bond between the
base of the mirror and the glass. Have an
assistant support and remove the mirror as it
is released.
2If the original mirror is to be refitted,
thoroughly clean its base with methylated
spirit and a lint-free cloth. Allow a period of
one minute for the spirit to evaporate. Clean
the windscreen black patch in a similar
manner.
Refitting
3During the installation of the mirror, it is
important that the mirror base, windscreen
black patch and the adhesive patch are not
touched or contaminated in any way,
otherwise poor adhesion will result.
4Prior to fitting the mirror, the vehicle should
have been at an ambient temperature of at
least 20ºC.
5With the contact surfaces thoroughly
cleaned, remove the protective tape from one
side of the adhesive patch, and press it firmly
into contact with the mirror base.
6If fitting the mirror to a new windscreen, the
protective tape must also be removed from
the windscreen black patch.
7Using a hairdryer or a hot air gun, warm themirror base and the adhesive patch for about
30 seconds to a temperature of 50 to 70ºC.
Peel back the protective tape from the other
side of the adhesive patch on the mirror base.
Align the mirror base and the windscreen
patch, and press the mirror firmly into
position. Hold the base of the mirror firmly
against the windscreen for a minimum period
of two minutes, to ensure full adhesion.
8Wait at least thirty minutes before adjusting
the mirror position.

3Where fitted, remove the trim from inside
the boot lid.
4Disconnect the wiring at the connectors
visible through the boot lid inner skin aperture.
5Attach a length of strong cord to the end of
the wires in the aperture, to act as an aid to
guiding the wiring through the lid when it is
refitted.
6Release the cable guide rubber grommet,
and withdraw the wiring loom through it. Untie
the cord, and leave it in the boot lid.
7Mark the position of the hinge arms with a
pencil.
8Place rags beneath each corner of the boot
lid, to prevent damage to the paintwork.
9With the help of an assistant, unscrew the
mounting bolts and lift the boot lid from the
car.

Testing
1The central locking module incorporates a
service-test mode, which is activated by
operating one of the lock position switches 8
times within 10 seconds. A buzzer will sound,
to indicate that the service-test mode is
operating, and to indicate that no faults have
been found in the system. If a fault has been
found, the system should be checked by a
Ford dealer or electrical specialist. The central
locking module also incorporates the alarm
system module.

1The windscreen and rear window on all
models are bonded in place with special
mastic, as are the rear side windows on
Estate models. Special tools are required to
cut free the old units and fit replacements;
special cleaning solutions and primer are also
required. It is therefore recommended that
this work is entrusted to a Ford dealer or
windscreen replacement specialist.
2Note that the windscreen contributes
towards the structural strength of the vehicle
as a whole, so it is important that it is fitted
correctly.

3Peel back the protective paper from the
rear face of the new moulding or emblem.
Carefully fit it into position on the panel
concerned, but take care not to touch the
adhesive. When in position, apply hand
pressure to the moulding/emblem for a short
period, to ensure maximum adhesion to the
panel.1The sunroof should operate freely, without
sticking or binding, as it is opened and
closed. When in the closed position, check
that the panel is flush with the surrounding
roof panel.
2If adjustment is required, open the sun
blind, but leave the glass panel shut. Unscrew
and remove the three lower frame-to-glass
panel retaining screws. Slide the lower frame
back into the roof.
3Loosen the central and front securing
screws. Adjust the glass roof panel so that it is
flush at its front edge with the roof panel, then
retighten the securing screws.
4Pull the lower frame forwards, and insert

functions of the various relays are given in the
Specifications (see illustration).
8If a component controlled by a relay
becomes inoperative and the relay is suspect,
listen to the relay as the circuit is operated. If
the relay is functioning, it should be possible
to hear it click as it is energized. If the relay
proves satisfactory, the fault lies with the
components or wiring of the system. If the
relay is not being energized, then either the
relay is not receiving a switching voltage, or
the relay itself is faulty. (Do not overlook the
relay socket terminals when tracing faults.)
Testing is by the substitution of a known good
unit, but be careful; while some relays are
identical in appearance and in operation,
others look similar, but perform different
functions.9The central timer module located on the
bottom of the main fusebox incorporates its
own self-diagnosis function. Note that
diagnosis cannot take place if the heated rear
window is defective.
10To activate the system, press the heated
rear window button while the ignition is being
switched on, then release the button. Operate
the light switch, washer pump switch and all
of the door switches one after the other, and
check that the buzzer confirms that the input
signals are correct.
11Now move the wiper lever to the
intermittent wipe position, and check the
output signals by operating the same
switches.
12The self-diagnosis function is turned off
by switching the ignition off and on again.

Coding
1If a Ford “Keycode” unit is fitted, and the
unit and/or the battery is disconnected, the
unit will not function again on reconnection
until the correct security code is entered.
Details of this procedure are given in the
“Ford Audio Systems Operating Guide”
supplied with the vehicle when new, with the
code itself being given in a “Radio Passport”
and/or a “Keycode Label” at the same time.
2For obvious security reasons, the re-coding
procedure is not given in this manual - if youdo not have the code or details of the correct
procedure, but can supply proof of ownership
and a legitimate reason for wanting this
information, the vehicle’s selling dealer may
be able to help.
3Note that these units will allow only ten
attempts at entering the code - any further
attempts will render the unit permanently
inoperative until it has been reprogrammed by
Ford themselves. At first, three consecutive
attempts are allowed; if all three are incorrect,
a 30-minute delay is required before another
attempt can be made. Each of any
subsequent attempts (up to the maximum of
ten) can be made only after a similar delay.
Removal
4Disconnect the battery negative (earth)
lead.
5Where fitted, prise the cover/surround from
the front of the radio/cassette player. Note
that the cover is not fitted to all models.
6In order to release the radio retaining clips,
two U-shaped rods must be inserted into the
special holes on each side of the radio (see
illustration). If possible, it is preferable to
obtain purpose-made rods from an audio
specialist, as these have cut-outs which snap
firmly into the clips so that the radio can be
pulled out. Pull the unit squarely from its
aperture, or it may jam. If the unit proves
difficult to withdraw, remove the cassette tray
(or where applicable, the CD player) frombeneath the unit, then reach through the
aperture and ease it out from behind.
7With the radio partly withdrawn, disconnect
the feed, earth, aerial and speaker leads.
Where applicable, also detach and remove
the plastic support bracket from the rear of
the unit.

6Refitting is a reversal of removal. With the
leads reconnected to the rear of the unit,
press it into position until the retaining clips
are felt to engage. Reactivate the unit by

reduces the risk of seizing on fasteners that
are subjected to high temperatures, such as
exhaust manifold bolts and nuts.

heat resistance, commonly used in the
composition of brake friction materials.Asbestos is a health hazard and the dust
created by brake systems should never be
inhaled or ingested.
AxleA shaft on which a wheel revolves, or
which revolves with a wheel. Also, a solid
beam that connects the two wheels at one
end of the vehicle. An axle which also
transmits power to the wheels is known as a

that pinch the brake disc when the brakes are
applied. Brake pads consist of a friction
material bonded or riveted to a rigid backing
plate.
Brake shoeThe crescent-shaped carrier to
which the brake linings are mounted and
which forces the lining against the rotating
drum during braking.
