Removal
1Disconnect the battery negative lead.
2For improved access, remove the securing
screws and unclip the lower and upper
steering column shrouds.
3Insert the ignition key and turn to position
“I”, then, working through the access hole,
depress the spring clip using a suitable tool
and pull the key to withdraw the lock barrel
and cylinder from the ignition switch housing.
The spring clip access hole is shown (see
illustration). Note that, on certain models, the
spring clip must be released by inserting the
tool through a small circular hole at the top of
the switch housing, above the rectangular slot
shown. Slight movement of the key may be
necessary to allow removal of the barrel and
cylinder.
4To remove the lock barrel from the cylinder
insert the key fully into the barrel and remove
the retaining circlip, taking care not to
damage the circlip location, then withdraw the
key approximately 5.0 mm (0.2 in) to retract
the lock barrel securing lug, and withdraw the
barrel from the cylinder.
5To remove the ignition switch, disconnect
the wiring plug, then remove the two grub
screws and withdraw the switch.
Refitting
6Refitting is a reversal of removal, bearing in
mind the following points.
7Note that the lock barrel can only be fitted
to the cylinder in one position, and check with
the key fully inserted that the barrel can be
turned from position “O” to “Ill” satisfactorily.
8The open jaws of the lock barrel retaining
circlip must align with the keyway register on
the cylinder, and the cylinder retaining circlip
must locate in the slot in the ignition switch
housing.
9On completion, check the operation of the
steering lock and ignition switch in all
positions.
1Disconnect the battery negative lead.
2Remove the securing screws and unclip the
lower and upper steering column shrouds.
3Remove the two securing screws and
disconnect the two wiring plugs, then
withdraw the switch from the steering column.
4Refitting is a reversal of removal.
1Disconnect the battery negative lead.2The relay is located on a bracket above the
steering column. Access is gained either by
removing the driver’s side lower facia panel or
the instrument panel.
3Unclip the relay from the bracket, and
disconnect the wiring plug (see illustration).
4Refitting is a reversal of removal. Check for
correct operation before refitting the facia
panel or instrument panel.
The procedure is identical to that described
for the direction indicator switch, except for
the additional removal and refitting of an earth
lead (see illustration).
1For automatic transmission models, refer to
Chapter 7, PartB. For manual gearbox
models, proceed as follows:
2Disconnect the battery negative lead.
3Apply the handbrake, jack up the front of
the vehicle and support on axle stands (see
“Jacking and Vehicle Support”).
4Working underneath the vehicle,
disconnect the wiring plug, then unscrew the
switch from the gearbox extension housing.
5Refitting is a reversal of removal, but make
sure that the wiring is routed clear of the
exhaust system.1Disconnect the battery negative lead.

2Using a thin-bladed screwdriver, carefully
prise the switch from the facia panel.
3Disconnect the wiring plug and withdraw
the switch.
4Refitting is a reversal of removal.

5Proceed as described in paragraphs 2 to 4.
Heater blower switch
6Carefully pull off the switch knob, using
pliers with padded jaws if necessary.
7Using a thin-bladed screwdriver, prise out
the switch front plate from the facia panel.
8Squeeze the switch retaining tabs, then
withdraw the switch and disconnect the wiring
plug (see illustration).
9Refitting is a reversal of removal.
Loudspeaker balance joystick
10Using a thin-bladed screwdriver, carefully
prise the joystick front plate from the facia
panel.
11Twist the joystick assembly retaining ring
anti-clockwise and remove the ring.
12Working behind the facia panel,
disconnect the wiring plug and slide out the
joystick assembly.

Clock illumination lamp
26Remove the clock.
27The bulb is a bayonet fit in the rear of the
clock.
28Refitting is a reversal of removal.
1Disconnect the battery negative lead.
Removal and refitting
2Detach the wiring connector at the left-hand
bonnet hinge, and attach a length of string to
the end of the wire running from the lamp.
3If necessary, remove the underbonnet
insulation by prising out the two-piece plastic
securing clips, then working at the lamp, pull the
wiring and the string through the bonnet panel.
4Detach the string from the end of the wire,
and remove the screw securing the lamp to
the bonnet. Withdraw the lamp.
5Commence refitting by attaching the end of
the wiring to the string, and pulling the string
and wiring through the bonnet panel. Further
refitting is a reversal of removal.
Bulb renewal
6Simply press and twist the bulb to remove it
from the bulbholder (see illustration).
7Refitting is a reversal of removal.
Removal
1The horn(s) is/are located in front of the
radiator beneath the front panel (see
illustration). The horn(s) may be located on
either side of the vehicle depending on model.
2Disconnect the battery negative lead.
3Disconnect the wiring from the horn, then
unscrew the securing nut and washer and
withdraw the horn and bracket assembly
complete.
4Repeat the operations for the remaining
horn where applicable.
Refitting
5Refitting is a reversal of removal.
Removal
1On models fitted with a trip computer,
remove the speed sender unit.
2Remove the instrument panel.
3Pull the cable through the bulkhead into the
engine compartment, and where applicable
release it from the securing clips. On models
fitted with a trip computer, the upper section
of the cable can now be removed.
4Apply the handbrake, jack up the front of
the vehicle and support on axle stands (see
“Jacking and Vehicle Support”).
5On vehicles with a manual gearbox, extract
the circlip securing the cable end to the
extension housing and withdraw the cable
end (see illustration).
6On vehicles with automatic transmission,
remove the securing screw and disconnect
the cable end from the extension housing.
7The cable can now be withdrawn from the
vehicle, noting its routing so that it can be
refitted in the same position.
Refitting
8Refitting is a reversal of removal, but where
applicable, ensure that the speedometer
cable rubber sleeve is in place over the square
inner drive on the cable connector, and not in
the speedometer head. Position the cable so
that the coloured bands on the cable sheath
line up with the bulkhead grommet and the
clips in the engine compartment. Route the
cable as noted during removal.9On completion, pull the speedometer cable
from within the engine compartment to ensure
that the cable is straight between the
instrument panel and the bulkhead grommet.
1The wiper blades should be renewed when
they no longer clean the glass effectively.
2Lift the wiper arm away from the glass.
3With the blade at 90º to the arm, depress
the spring clip and slide the blade clear of the
hook, then slide the blade up off the arm.
4If necessary extract the two metal inserts
and unhook the wiper rubber.
5Fit the new rubber and blade in reverse
order, making sure where necessary that the
cut-outs in the metal inserts face each other.
Windscreen and rear wipers
1Lift the hinged covers and remove the nuts
and washers securing the arms to the spindles.
2Mark the arms and spindles in relation to each
other then prise off the arms using a screwdriver.
Take care not to damage the paintwork.
3Refitting is a reversal of removal.

4The procedure is as described in
paragraphs 1 to 3, but the washer hose must
be disconnected from the nozzle on the wiper
arm (see illustration).
