3Carefully peel away the foam rubber sheet
in the area of the lock motor.
4Remove the two securing screws, unhook
the motor from the lock operating rod and
disconnect the multi-plug. Remove the motor
(see illustration).
5A defective lock motor must be renewed.
No spare parts are available.
6Refit by reversing the removal operations,
then adjust the lock linkage as follows.
7Move the locking lever to the “unlocked”
position. Slacken the screw which secures the
interior handle/lock lever assembly, push the
assembly forwards as far as it will go and
tighten the screw.1Remove the window operating mechanism,
complete with motor.
2Make sure that the spring is holding the
lever against its stop, then remove the three
bolts and separate the motor from the
operating mechanism (see illustrations).
Caution: Uncontrolled release of the spring
can cause injury and damage.
3Refit by reversing the removal operations.
Check the operations of the motor before
refitting the door trim panel.
Front height and fore-and-aft
motors
1Move the front seat rearwards as far as
possible to improve access. Remove the two
securing bolts from the front of the seat frame
and tip the seat backwards.
2Unbolt and remove the motor(s). Each
motor is secured by two bolts (see
illustration).Make sure that the drive cables
come away from the worm drives without
difficulty - if not, disconnect one end of the
worm drive too.
3If only one motor is being removed, free itsspade connectors from the common multi-
plug washer removing the plug shell (see
illustration).It is probably easier to remove
both motors and deal with the connectors on
the bench.
4Refit by reversing the removal operations.
Check for correct operation of the motors on
completion.
Front recline motor
5Remove the front seat.
6Remove the seat cover and cushion.
7Remove the two securing bolts (see
illustration),disconnect the multi-plug and
withdraw the motor from the reclining
mechanism.

pinion gear meshes with the reclining
mechanism gear. Connect the multi-plug and
secure the motor with the two bolts.
9Refit the seat cover and cushion, then refit
the seat to the vehicle.

10Remove the trim panel from the left-hand
side of the luggage area.
11Remove the three Torx screws which
secure the motor and reclining mechanism.
Disconnect the multi-plug (next to the seat
squab) and remove the motor(see

1Remove the overhead console.
2Remove the three bolts which secure the
motor (see illustration).Lower the motor,
disconnect the multi-plug and remove it.
Recover the relay.
3When refitting, make sure that the motor
drivegear meshes with the roof operating
mechanism. Refit the relay, reconnect the
multi-plug and secure the motor with the three
bolts.
4Check the operation of the motor, then refit
the overhead console.1All vehicles are fitted with an electrical
speedometer sender unit instead of a
mechanical cable. The sender unit is located on
the left-hand side of the transmission extension.
2Raise and securely support the front of the
vehicle. Place a drain pan underneath the
speedometer sender unit.
3Remove the securing bolt, pull the sender
unit out of the transmission and disconnect
the multi-plug (see illustration). Be prepared
for some spillage of gearbox oil or ATF
(automatic transmission fluid).
4If a new sender unit is being fitted, transfer
the driven gear and circlip from the old unit.
On automatic transmission models, also
transfer the O-ring.
5If the old sender unit had two connecting
wires and the new unit has three, the brown
wire must be cut at the multi-plug and an earth
tag fitted (see illustration).Consult a Ford
dealer if in doubt.
6Fit the new sender unit, using a new bolt
(M6 x 25 mm for manual gearbox, M6 x 35 mm
for automatic transmission). Besides the
sender unit, the bolt also secures the new
earth tag (when applicable), the radio earth
strap and the multi-plug retaining bracket.
7Connect the multi-plug and fit it to the
bracket.8If any spillage of gearbox oil or transmission
fluid occurred, top-up the level before the
vehicle is next run.

plug and remove the motor and bracket.
4The bracket can be unbolted from the motor
if wished. No spare parts for the motor are
available.
5Commence refitting by offering the motor
and bracket to the tailgate. Secure the
assembly with the three bolts, then reconnect
the wiring and secure the earth tag.
6Switch on the ignition and operate the rear
wiper control briefly so that the motor stops in
the “parked” position.7Refit the wiper arm and blade. Wet the
window and operate the rear wiper control
again to check the function of the motor.
8Switch off the ignition and refit the tailgate
interior trim panel.
Windscreen and rear washer jets are
removed simply by prising or pulling them
from their locations (see illustration).
Headlight washer jets can be unclipped from
their holders after disconnection of the high
pressure hose from the jet.
To remove a washer pump, first syphon out
the contents of the reservoir. Disconnect the
wiring and the hose from the pump, then pull
the pump out of its grommet in the reservoir.
Renew the grommet if necessary when
refitting the pump.

the bench if wished.15Refit by reversing the removal operations.
Use new fuel pipe clips if the old ones were
damaged during removal.
Note that if a fault develops in the AWS,
thorough testing and fault finding should be
left to a Ford dealer or other competent
specialist. Unskilled or uninformed testing may
cause further damage. When checking wires
or sensors for continuity, disconnect the
control assembly and bulb failure module first,
otherwise damage may be caused.

the cable so that it is slightly slack when the
throttle linkage is in the idle position (pedal
released).
21On 2.0 litre carburettor models, the
stepper motor plunger must be withdrawn
before the cable is adjusted. Proceed as
follows.
22Observe the stepper motor plunger. Have
an assistant switch on the ignition for a few
seconds, then switch it off again. When the
ignition is switched off, the stepper motor
plunger will retract fully (“vent manifold”
position). Disconnect the battery negative lead
while the stepper motor plunger is retracted.

The alarm system is available as an optional
extra. On vehicles so equipped, the alarm is
automatically set by locking the driver’s or
front passenger’s door with the key. After a
brief delay (approximately 20 seconds), the
alarm will be set off if the doors, bonnet or
tailgate are opened.
The only way to disarm the alarm system is
by unlocking one of the front doors with the
key. Even if the key is used to open the
tailgate, if the alarm is set it will go off.

The components of the alarm system are a
control module, tripping switches, activating
switches, an alarm horn and a signal buzzer.
The control module is located behind the
facia. It determines whether the alarm is set or
not, monitors the tripping switches and the
ignition circuit, and limits the duration of the
alarm to 30 seconds. This last item is a legal
requirement. The control module also
operates the signal buzzer to tell the driver
that the alarm is set, and controls the activator
delay.
The tripping switches on the doors and
tailgate are the same as those used for “open
door” warnings in the AWS. The bonnet switch
is peculiar to the alarm system.
The activating switches are fitted to the
front door lock barrels, where they are
activated by a lug on the end of the barrel.
They only make contact momentarily as the
lock is operated.
The alarm horn is mounted next to the
battery. Both the horn and its leads are
claimed to be inaccessible without opening
the bonnet. The signal buzzer is also mounted
under the bonnet.
No service, repair or component renewal
procedures have been published for the alarmsystem components on earlier models. Any
problems arising which cannot be dealt with
by component substitution should therefore
be referred to a Ford dealer.
