Location
1The AWS control unit, and (when fitted) the
bulb failure monitor, are located behind the
glovebox on models up to 1987.
2On models from 1987, the control and bulb
failure modules are located behind the driver’s
side footwell trim panel.
Testing
3Thorough testing and fault finding should
be left to a Ford dealer or other electrical
specialist, having test equipment. Unskilled or
uninformed testing may cause damage.
4Investigation of malfunctions should begin
by checking that all wiring is intact and
securely connected. If checking wires or
sensors for continuity, always disconnect the
control unit and/or bulb failure monitor before
so doing, otherwise damage may be caused.
5Note that false oil level readings can result if
the car is parked on a slope. False bulb failure
warnings may occur if incorrect wattage bulbs
are fitted.
Removal and refitting
6Disconnect the battery negative lead.
Warning lamp bulbs
7Remove the single screw from the top edge
of the facia panel in which the warning lamps
are housed, then withdraw the facia panel
(see illustration).
8Twist the relevant bulbholder through 90º to
remove it from the rear of the facia panel. The
bulb is integral with the bulbholder and must
be renewed as a unit (see illustration).
9Refitting is a reversal of removal.
Graphic display unit and bulbs
10Remove the clock or trip computer.
11Remove the display unit retaining screw
and the retainer, then pull the unit forwards
and disconnect the wiring plug using a thin-
bladed screwdriver (see illustrations).
12To renew a bulb, remove the two securing
screws and pull the circuit board from the
back of the unit to reveal the bulbs. The bulbs
are a push-fit.
13Refitting is a reversal of removal.
Control unit and bulb failure monitor
14Unclip the trim panel from the lower edge
of the passenger side lower facia panel.
15On models up to 1987, pull off the two
clips to release the control unit/bulb failure
monitor mounting bracket. Depress the
retaining tab and disconnect the relevant
wiring plug, then remove the two securing
screws and withdraw the control unit/bulb
failure monitor (see illustration).
16On models from 1987, release the
retaining tang and carefully slide the control
unit/bulb failure monitor downwards. Depress
the retaining tab and disconnect the relevant
wiring plug, then withdraw the control
unit/bulb failure monitor.
17Refitting is a reversal of removal. Note
that when both a control unit and bulb failure
monitor are fitted, the control unit wiring plug
is coloured brown, and the bulb failure
monitor wiring plug is coloured green.
Ice warning sender
18This sender is located beneath the front
panel on the right-hand side of the vehicle.
19Where necessary, for improved access
remove the horn.
20Depress the two retaining tangs,
disconnect the wiring plug and withdraw the
sender unit from the slot in the front panel.
21Refitting is a reversal of removal.
Door/tailgate/boot lid ajar switches
22Remove the relevant lock.
23Pull the switch from its location in the lock
body, disconnect the wiring plug (if not
already done) and withdraw the switch (see
illustration).24Refitting is a reversal of removal.
Low coolant level sensor
25Refer to Chapter 3.
Low washer fluid level switch
26Syphon out the contents of the reservoir,
then prise the switch from its grommet using a
thin-bladed screwdriver. Disconnect the
wiring plug.
27Refitting is a reversal of removal, using a
new grommet if necessary. Use a little liquid
detergent as a lubricant.
28On completion, refill the reservoir.
Low fuel level switch
29The switch is integral with the fuel level
sender unit. Details of fuel level sender unit
removal and refitting are given in Chapter 4.
Low oil level switch
30The switch is integral with the oil level
dipstick. To remove, simply withdraw the
