removal procedure. Refit the timing belt and
tensioner as described in Chapter 2C, noting
that a new tensioner spring and retaining pin
must be fitted if the timing belt has been
removed for the first time. Tighten all
fasteners to the specified torque, and refill the
system with coolant as described in Chap-
ter 1.

Heater controls
1 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Refer to Chapter 12 and remove the radio.
3 Pull off the heater fan motor control knob,
then move the air distribution and
temperature controls fully to the right. Unclip
and remove the heater slide facia towards the
left-hand side of the vehicle, removing the
slide control knobs only as necessary, and
disconnecting its bulbholder (bayonet type) as
it is withdrawn.
4 Squeeze the two release tabs together on
the heater fan motor control switch, and
remove it, disconnecting its multi-plug as it is
withdrawn.
5 Disconnect the heater control cables from
the heater casing assembly by releasing the
outer cable abutments and disengaging the cable inner cores from their flap operating
mechanisms
(see illustration) .
6 Undo the three heater control panel
securing screws, and remove the control
panel (with its cables attached) from behind
the facia (see illustration) .
7 Disconnect the heater control cables from
their control panel levers, as required, by
releasing their outer cable clamping covers
and inner cable core securing clips (see
illustrations) .
8 If renewing a heater control panel, note that
the new unit, is supplied with control cables
and assembly aids fitted (see illustration).
The assembly aids ensure correct heater
control adjustments during fitting, and must
be removed thereafter. 9
Refitting is a reversal of the removal
procedure, adjusting the heater control cables
to complete. The adjustment is made
automatically by moving the heater slide
control levers from their left-hand stop to their
right-hand stop. When moving the control
levers, a considerable amount of resistance
may be encountered, which must be
overcome.
Heater fan motor and resistor
assembly
10 Disconnect the battery negative (earth)
lead (refer to Chapter 5A, Section 1).
11 Depending on engine type, refer to the
relevant Part of Chapter 4 and remove the air
cleaner if necessary, to gain access to the
bulkhead panel in the engine compartment.
12 Remove the expansion tank as described
in Section 7.
13 Undo the retaining bolt and remove the
jack and wheelbrace.
14 Disconnect the modules on the bulkhead
panel. Release the wiring loom and any
connectors, cable-ties and hoses from the
bulkhead panel, and remove its rubber seal.
15 Remove the bulkhead panel. The panel is
secured by screws, with a nut at either end
(behind the panel), and is removed in two
sections.
16 Detach and remove the cover from the
heater fan motor assembly (see illustration).

the inside face of the cover to remove and fit
the fuses (see illustrations) .
2 To remove a fuse, use the tweezers
provided to pull it out of the holder. Slide the
fuse sideways from the tweezers. The wire
within the fuse is clearly visible, and it will be
broken if the fuse is blown.
3 Always renew a fuse with one of an
identical rating. Never renew a fuse more than
once without tracing the source of the trouble.
The fuse rating is stamped on top of the fuse.
4 With the exception of the indicator flasher
relay, the remainder of the relays are fitted to
the reverse side of the main fuse/relay board.
Access is as described in paragraph 1.
5 The various relays can be removed from
their respective locations on the fuse board by
carefully pulling them from the sockets.
6 The direction indicator flasher relay is
attached to the multi-function switch unit on
the steering column. Access to the relay is
made by undoing the retaining screws and
removing the steering column shrouds. The
relay can then be withdrawn from the switch.
7 If a system 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 energised. If the relay proves
satisfactory, the fault lies with the
components or wiring of the system. If the
relay is not being energised, then it is not
receiving a main supply voltage or a switching
voltage, or the relay is faulty.

Ignition switch (loom plate and
lock barrel)
1 Disconnect the battery negative (earth) lead
(refer to Chapter 5A, Section 1).
2 Remove the manual choke control knob,
where fitted, by depressing the lug securing it,
and pulling it from its shaft. The lug is found
on the side of the control knob shank. 3
Remove the lower steering column shroud
by undoing its four retaining screws, then
detach the choke warning light switch/pull
control assembly from the lower shroud by
unscrewing its retaining collar (bayonet-type
fixing), using a suitable tool to locate in the
collar recesses.
4 Remove the two screws securing the upper
steering column shroud from above, and the
two screws securing it from below, the latter
accessible only with the lower shroud
removed.
5 Disconnect the ignition switch wiring multi-
plug connector. Insert a thin-bladed
screwdriver into the lock tab aperture, release
the locking tab and remove the loom plate
from its location on the left-hand side of the
steering column.
6 Where applicable, undo the single screw
and withdraw the Passive Anti-Theft System
(PATS) transceiver from the ignition
switch/steering lock barrel.
7 Insert the key and turn the ignition switch to
position ”I”. Depress the lock barrel plunger
through the steering column lock housing. As
the lock barrel plunger is depressed, pull
on the ignition key to remove the lock barrel
(see illustration) .
8 Refitting is a reversal of the removal
procedure. When relocating the switch to the
steering lock, the barrel driveshaft must align with the switch shaft as it is pushed into
position. Check the switch for satisfactory
operation on completion.
