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.
Rocker switches and push button

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.
Instrument panel illumination and
intermittent wipe rheostats
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.

securing screws, and withdraw the instrument
panel surround (see illustration).
6On models fitted with a trip computer,
unscrew the knurled nut and disconnect thespeedometer cable from the speed sender
unit on the engine compartment bulkhead.
7Detach the speedometer cable grommet
from the engine compartment bulkhead.
8Remove the two upper and two lower
securing screws, and withdraw the instrument
panel sufficiently to disconnect the
speedometer cable and the wiring plugs. The
speedometer cable can be released by
pushing the ribbed surface towards the centre
of the cable to free the catch. Remove the
instrument panel (see illustration).
9Refitting 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.
10On 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.
Models from 1992
11The procedure is as described above but
note that both instrument panel surround
lower securing screws are located beneath
plastic covers (see illustration).

renewed as a unit (see illustrations).
4Refitting is a reversal of removal.
Panel lens
5Remove the three upper and three lower
securing screws and withdraw the lens from
the instrument panel.
6Refitting is a reversal of removal, but ensure
that the two locating pegs on the upper
corners of the instrument panel protrude
through the lens, and locate the lugs on the
lower edge of the lens in the cut-outs in the
instrument panel.

two securing screws from the front of the
gauge assembly, then withdraw the combined
gauge assembly from the printed circuit board.25On “high specification” models, simply
withdraw the combined gauge assembly from
the printed circuit board.

18Remove the four securing screws,
disconnect the wiring and withdraw the
loudspeaker. Note that on models with an
integral heated rear window/radio aerial, the
aerial amplifier unit is combined with one of
the loudspeaker units.19Refitting is a reversal of removal.
High frequency units
20These units are used to reproduce high
frequencies only, and incorporate an
electronic filter network which must not be
disconnected or bypassed. The units are
located in the lower facia panels.
21The removal and refitting procedure is as
described for the lower facia panel-mounted
loudspeakers earlier in this Section, but take
care not to damage the extremely fragile
speaker cones.
Removal
1Some “high specification” models are fitted
with an audio power amplifier, which is
mounted as a separate unit beneath the radio/
cassette unit. To remove the unit proceed as
follows.
2Disconnect the battery negative lead.
3Remove the two screws under the top edge
of the power amplifier unit.
4Slide the unit forwards from the facia panel,
until the wiring plugs can be disconnected.
Disconnect the wiring plugs and remove the
unit.

DIN fixing
8An increasing number of radio/cassette
players have DIN standard fixings. Two
special tools, obtainable from in-car
entertainment specialists, are required for
removal.
9Disconnect the battery negative lead.
10Insert the tools into the holes in the front
of the radio/cassette player and push them
until they snap into place. Pull the tools
outwards to release the unit (see illustration).
11Pull the unit forwards and disconnect the
wiring plugs and the aerial lead. Remove the
unit from the facia panel.
12To refit the radio/cassette player,
reconnect the wiring and the aerial lead, then
simply push the unit into its bracket until the
retaining lugs snap into place.
