Starter motor brushes
(later models) - renewal#
25When renewing the starter motor brushes
on later models, the old brushes will need to
be crushed (in a vice or with a hammer) and
their leads then soldered to the new brushes.
Fuses - later models
26The fuse arrangement is slightly different
on later models, but the circuits protected are
still identified by a symbol. Refer to the
Specifications Section for full details. Note
also the terminal block with plastic cover,
which can be used to isolate the battery from
the electrical system by disconnecting the
leads from the terminals (photos).
Relays (Turbo ie models) -
general
27On Turbo ie models, the relays mounted
in the fuse block are as shown in Fig. 13.103.
Additional relays are located as follows:
Headlamp relay - on lead under main fuse
blockFuel injection system main control relay -
adjacent to airflow meter
Headlamps later models
28The headlamp units fitted on later models
differ according to model, but the bulb and
unit replacement details are generally the
same as described for previous models in
Chapter 9. Note that the rubber cover can
only be fitted with the tab to the top as shown
(photo).
Headlamp beam adjusters for
load compensation - later
models
29Some later models are fitted with
headlamp beam adjusters which allowtemporary resetting to be made (such as
when the car is fully loaded). Access to these
adjusters is made by lifting the bonnet (photo).
30Turn the adjusters anti-clockwise to lower
the beam to the normal level or clockwise to
raise the beam (when the car is unloaded).
Repeat the procedure on the opposite
headlamp unit an equal amount.
31Other later models have separate
horizontal and vertical beam adjusters,
positioned as shown (photos). A load
compensating lever is attached to the
adjusters to enable temporary resetting of the
headlamp beams, without changing the
normal adjustment. Turn the lever to the
appropriate side (right or left) to make the
adjustment as required. The normal setting

procedure. Reset the clock on completion.
Central door locking system
84Certain later models, equipped with a
central door locking system, have an infra-red
remote control for opening the door locks.
85It is important that the battery used in the
hand control is renewed when necessary with
one of identical type (Duracell 7H34). This is
only available as a FIAT spare part (No
7595393).
86The remote control door lock receiver unit
can be removed by carefully prising it free
from the roof panel and disconnecting the
wiring connector (photo).
87If either this unit or the hand control are
renewed at any time, recoding will be
necessary and this is a task best entrusted to
a FIAT dealer.

switches -
removal and refitting
Á
91The window regulator switches on later
models are located in the door pull trim. To
remove a switch, prise it free from the trim by
inserting a thin-bladed screwdriver under the
switch flange, then lever it free from its
aperture (photo). Take care not to damage thetrim. Detach the wiring connector to fully
remove the switch.
92Refit in the reverse order of removal and
then check the operation of the switch.

94Remove the bonnet as described in
Chapter 12.
95Remove the wiper arm and blade as
described in Chapter 9, then unscrew and
remove the pivot nut (photo).
96Undo the air inlet grille retaining screws
noting that two are not fitted with washers.
Where applicable, remove the washer
reservoir filler cap from the reservoir neck
protruding through the grille. Carefully prise
free and lift the air inlet grille clear of the body.

(photo).
6When refitting the mirror, engage the front
of the socket on the ball and then twist the
mirror rearwards and upwards.
Exterior
7On models without remotely-controlled
type exterior mirrors, the ball-jointed mirror is
held in position by the two self-tapping
screws which secure the triangular trim plate
inside the car (photos).
8To dismantle the mirror, extract the balljoint
fixing screw, but take care as considerable
force is exerted by the interior coil spring
(photo).
Door armrestÁ
9A redesigned armrest is used on somemodels. This is simply secured by two
self-tapping screws (photo).
Tailgate (Turbo ie model) -
component
removal and refitting
Á
10The tailgate on these models is of plastic
injection-moulded type, with a bonded
window glass.
11Renewal of the glass or repair of the
tailgate should be entrusted to your FIAT
dealer or a specialist repairer, due to the need
for special products and techniques.
12To remove the tailgate lock and handle,
open the tailgate and extract the lock handle
screws.
13Prise off the link rod socket from the
ball-pin (photos). Unbolt and remove the
handle and lock.
14A remote type of tailgate release is fitted,
with a control handle located by the driver’s
seat. Access to the handle can be obtained by
removing the seat and sill trim, and peeling
back the carpet.
15If a new cable is to be fitted, disconnect it
from the tailgate latch, tape the new cable to
the old one, and draw it carefully around the
side panel and sill trim (photo).
16To remove the tailgate wiper motor, first
take off the wiper arm and blade.
17Extract the plastic clips and take
off the wiper motor protective cover.
Disconnect, unbolt, and remove the wiper
motor (photo).

Removal - front
24Remove the radiator grille as previously
described, to provide access to the bumper
upper mounting screws (photo).
25The ends of the bumpers are secured withbolts and captive nuts but to reach them, the

removal and refittingª
31These have toggle-type catches and
hinges bolted directly through the glass
(photo).
32To remove the window glass, have an
assistant support it, and then unscrew the
cross-head hinge screws and the toggle catch
anchor plate screws. Lift the glass away. If the
toggle catch must be removed from the glass,
first drive out the handle pivot pin and then,
using a pin wrench or circlip pliers, unscrew
