steering wheel and horn pad are fully covered in the
Steering section.

11. SWITCHES AND CONTROLS
IGNITION SWITCH
To Remove and Install
Disconnect the negative battery terminal.
Remove the retaining screws from the steer-
ing column cover. Unclip and separate the upper and lower
steering column covers and remove the upper cover. Release the column adjusting lever and re-
move the lower cover by guiding the column adjusting
lever through the hole in the upper end of the cover.

Disconnect the ignition switch wiring at the
switch. Remove the retaining screw and withdraw
the ignition switch fr om the lock assembly.
Installation is a reversal of the removal procedure.

COMBINATION SWITCH
The combination switch is mounted at the top of
the steering column and incorporates two switches.
The parking lamp, headlamp, headlamp flasher, head-
lamp dipper and turn signal lamps are operated by a
lever on the right hand side. A lever on the left hand
side operates the windscreen washer and wiper switch.

These switches can be re newed without removing
the combination switch.

To Remove and Install Switches
Remove the retaining screws from the steer-
ing column cover.
Unclip and separate the upper and lower
steering column covers and remove the upper cover.

View of the combination switch removed from the
vehicle.
Release the column adjusting lever and re-
move the lower cover by guiding the column adjusting
lever through the hole in the upper end of the cover. Disconnect the wiring connectors from the
applicable switch. Remove the retaining screws located at the
top and bottom of the applicable switch and remove
the switch. Installation is a reversal of the removal procedure.

To Remove and Install Combination Switch Base
Disconnect the negative battery terminal.
Remove the steering wheel as described in
the Steering section Remove the retaining screws from the steer-
ing column cover. Unclip and separate the upper and lower
steering column covers and remove the upper cover.
Release the column adjusting lever and re-
move the lower cover by guiding the column adjusting
lever through the hole in the upper end of the cover.

12. INSTRUMENT CLUSTER
TO REMOVE AND INSTAL
Disconnect the negative battery terminal.
Remove the retaining screws from the instru-
ment cluster surround. Carefully withdraw the instrument cluster
surround from the instrument panel sufficiently to
enable the wiring to be disconnected. Remove the
surround from the vehicle.

FLEXIBLE PRINTED
CIRCUIT

Rear view of the instrument cluster removed from the
vehicle.

(4) Remove the instrument cluster assembly
retaining screws and gently ease the assembly from the
instrument panel sufficiently to enable the wiring to be
disconnected.

If necessary, remove the instruments as follows:
Carefully depress the retaining clips on the
front lens and remove the front lens. On models equipped with a tachometer, slide
the plastic rib from between the speedometer and the
tachometer. Remove the screws retaining the speedome-
ter and the tachometer or fuel/temperature gauges
from the rear of the instrument cluster.
CLUSTER ASSEMBLY

(d) Withdraw both instruments from the front of
the instrument cluster being careful as these instru-
ments are held by protruding pin terminals.

NOTE: Do not touch the faces of the instru-
ment dials as they mark easily.

(e) On models equipped with a tachometer,
remove the retaining nuts and remove the tempera-
ture and/or the fuel gauge from the cluster assembly.

Installation is a reversal of the removal procedure
ensuring that all electrical connectors are correctly
installed.

13. BLOWER FAN
The removal and installation procedure for the
blower fan is described in the Cooling and Heating
Systems section.

14. RADIO/CASSETTE
TO REMOVE AND INSTAL
Disconnect the negative battery terminal.
Remove the release hole covers on each side
of the radio/cassette.

Using the radio/cassette removal tools during removal of the unit.
Construct the special tools as illustrated,
insert both tools into the release holes on the radio/
cassette and carefully withdraw the radio/cassette
from the mounting bracket.
Disconnect the wiring harness terminal plug
and remove the radio/cassette.
Installation is a reversal of the removal procedure
with attention to the following points:

Remove the special tools from the radio/
cassette, connect the wiring harness terminal and push
the radio/cassette into the mounting bracket. Install the release hole covers on each side
of
the radio/cassette.
15. LAMP UNITS

HEADLAMPS
To Remove and Install
Disconnect the negative battery terminal.
If removing the drivers side headlamp on 1.8
liter engines, remove the bo lt securing the air cleaner
intake duct and remove the air cleaner intake duct.

Dismantled view of the headlamp assembly.
Remove the radiator grille as described in
the Body section. Remove the bolt and nut from the front and
rear of the inner headlamp. Remove the side indicator lamp assembly
and remove the bolts from the side of the headlamp.
Maneuver the headlamp inner side out first
and remove the headlamp from the vehicle. Installation is a reversal of the removal procedure.

To Adjust Headlamp Aim
Ensure that the tires are inflated to the
correct pressure and that the vehicle is positioned on
level ground.
The vehicle should be unladen, with a full
fuel tank and the driver sitting in the vehicle. When using a headlamp aiming machine,
refer to the manufacturers instructions for equipment
being used.

216 Electrical System

NOTE: While checking the operation of the
fusible link, loosely connect the battery-
terminal only, to safeguard against damage
to the wiring harness.

(5) If the circuit is still inoperative or the fusible
link burns out again, refer the problem to an auto-
motive electrician.

RELAY LOCATIONS
The various relays employed in the vehicle elec-
trical system are located behind the fusible links
adjacent to the washer bottle in the engine compart-
ment, on the engine compartment bulkhead, under
the windscreen wiper motor and in the fuse box at the
lower right hand side of the dashboard.

The engine compartment relays power the radia-
tor fan, horn, condenser fan, bulb check, automatic
transaxle neutral safety switch, air conditioner and
condenser motor.


Installed view of the fuse box relays.
The fuse box relays power the fuel pump, ignition,
some accessories and the el ectronic control module.

18. TRAILER WIRING
There are several brands of trailer wiring connec-
tors available with a variet y of pin configurations. The
most common is the seven pin type which provides
for two auxiliary circuits, usually used for reverse
lamps and electric trailer brakes.
