5The switches must be removed as a
complete assembly, and cannot be
dismantled. If one of the switches is faulty, the
complete assembly must be renewed.
6Remove the rear section of the centre
console, as described in Chapter 11.
7Release the securing clips, and withdraw
the switch assembly through the top of the
centre console.

Operating motors
9Remove the door window regulator, as
described in Chapter 11.
10To remove the motor assembly from the
front door window regulator, unscrew the
three motor securing nuts, and the single
screw securing the pulse pick-up unit to the
regulator assembly. Withdraw the motor,
complete with the pulse pick-up unit. Note
that if the motor or pick-up unit is/are faulty,
the two components must be renewed as an
assembly, as no spare parts are available (see
illustration).
11The motor assembly fitted to the rear door
window regulator is an integral part of the
regulator, and no attempt should be made at
dismantling. If faulty, the complete
motor/regulator assembly must be renewed,
as no spares are available.

55Airbag - general
All 1993 Cavalier models are available with
an airbag that is designed to prevent serious
chest and head injuries to the driver during an
accident. A similar bag for the front seat
passenger is also available on certain models.
Sensors in the centre of the car measure the
vehicle deceleration rate and pass these
signals to a microprocessor. This unit
analyses the sensor data and compares the
information with pre-programmed values
stored in its memory, triggering the airbag if
the deceleration is severe. The airbag is
inflated in 50 milliseconds by a gas generator
that forces the bag out of the module cover in
the centre of the steering wheel.
No repairs are possible on the airbag unit or
its associated parts. The contents of the
following Sections are confined to removal
and refitting of the airbag, purely for access to
other non-related components.
Should a fault be suspected on the airbag
unit, indicated by the warning light on the
instrument panel, or if the car has been
involved in an accident, however minor,
consult a Vauxhall dealer immediately. Do not
attempt to dismantle any of the airbag
components or carry out any work
whatsoever, other than the procedures
described in the following Sections.
On vehicles fitted with a passenger side
airbag, do notfit accessories in the airbag
zone. Items like telephones, cassette storage
boxes, additional mirrors, etc., can be ripped off
and cause serious injury, if the airbag inflates.

Warning: Before starting any
work on airbag or related
components, disconnect the
battery. Cover the battery’s
terminals and wait a minimum of 1
minutes as a precaution against
accidental firing of the airbag unit. This
period ensures that any stored energy in
the back-up capacitor is dissipated.
Handle the airbag unit with extreme care
as a precaution against personal injury,
and always hold it with the cover facing
away from the body. If in doubt
concerning any proposed work involving
the airbag unit or its control circuitry,
consult a Vauxhall dealer or other
qualified specialist.

Note:On power steering models in particular,
it will be advantageous to jack up the front of
the car and support it on axle stands placed
under the body side members, so that the
steering wheel can be turned more easily.
Removal
1Disconnect the battery negative lead and
cover the battery terminal. Wait a minimum of 1
minute.
2With the steering wheel positioned in the
straight-ahead position, turn it 90°clockwise
so that the left-hand spoke is accessible from
the rear.
3Using a Torx type socket, undo the first
airbag retaining bolt from the rear of the
steering wheel (see illustration).
4Turn the steering wheel 180°anti-clockwise
so that the right-hand spoke is accessible
from the rear.
5Undo the second retaining bolt from the
rear of the steering wheel.
6Return the steering wheel to the
straight-ahead position then carefully lift up
the airbag unit.

Note: Read warning at the beginning of
Section 55, before starting work. A
two-legged puller will be required for this
operation. Note also that the steering wheel is
a very tight fit on the shaft.
Removal
1Remove the airbag unit as described
previously.
2Ensure that the steering wheel is in the
straight ahead position.
3From the centre of the steering wheel
unscrew the two screws securing the airbag
contact unit.4Using a screwdriver, prise back the tabs on
the lockwasher securing the steering wheel
retaining nut.
5Unscrew and remove the steering wheel
retaining nut and the lockwasher.
6Make alignment marks between the
steering wheel and the end of the column
shaft.
7A suitably small two-legged puller must
now be fitted to the steering wheel in order to
pull it from the column shaft.
8Once the steering wheel has been released
from the column shaft, disconnect the horn
wiring and remove the steering wheel.
Refitting
9Begin refitting by positioning the steering
wheel on the column shaft, ensuring that the
marks made on removal are aligned, and that
the wheel correctly engages with the airbag
contact unit. It may be necessary to tap the
steering wheel fully home on the column shaft
using a metal tube and socket.
10Reconnect the horn wiring.
11Refit the lockwasher and the steering
wheel retaining nut, and tighten the nut to the
specified torque. Bend up the lockwasher to
secure.
12Refit the two screws securing the airbag
contact unit.
13Refit the airbag as described previously.

necessary.
3Disconnect the contact unit wiring plug
below the steering column and withdraw the
contact unit from the column, noting its fitted
position as a guide to reassembly (see
illustration).

4Before refitting the contact unit, ensure that
the front wheels are in the straight-ahead
position.
5Place the contact unit on the column in the
correct position as noted during removal.
6Route the wiring harness under the steering
column lock/ignition switch and connect the
wiring plug.

62Wiring diagrams -general
1The wiring diagrams are of the current flow
type, each circuit being shown in the simplest
possible fashion. Note that since the diagrams
were originally written in German (to the DIN
standard), all wire colours and abbreviations
used on the diagrams themselves are in
German. Refer to the information given
overleaf for clarification.
2The bottom line of the diagram represents
the “earth” or negative connection; the
numbers below this line are track numbers,
enabling circuits and components to be
located using the key.
3The lines at the top of the diagram
represent “live feed” or positive connection
points. The line marked “30” is live at all
times, that marked “15” is live only when the
ignition is switched on.
4Numbers on the diagram that are framed in
square boxes at the end of a wire show the
track reference number in which that wire is
continued. At the point indicated will be
another framed number referring back to the
circuit just left.
5As an example of how to use the diagrams,
trace with the help of the following text the
reversing lamp switch circuit located between
track reference numbers 496 and 498 on the
1991 model year diagram on page 12•40.
6Starting at the top of track 497, the supply
for the circuit comes from the line “15”,
showing that the circuit is fed only when the
ignition is switched on, through fuse 22 (F22,rated at 10 amps). Note that this fuse can also
protect the feed for several other circuits,
some of which may not be applicable to the
vehicle being worked on.
7If the vehicle in question has a manual
transmission (MT), the circuit continues along
a black wire of 0.75 mm cross-section (as
shown by “SW 0.75” in the wire path), through
terminal 12 of connector X5 to the reversing
lamp switch S7. From the switch the circuit
continues along a white wire, with a black
tracer and of 0.75 mm cross-section (WSSW
0.75), through terminal 2 of connector X5 and
terminal 1 of connector X6, to the reversing
lamp bulbs (E17 and E18). The circuit is
completed by a brown wire from each
bulbholder to earth; in this case the “earth”
wire simply attaches the component to the
nearest piece of metal bodywork, but in other
cases earthing is achieved by the component
mounting and no wire is needed. The diagram
shows, as simply as possible, that when the
switch contacts (which are normally open) are
closed by the driver selecting reverse gear,
current is allowed to flow to earth through the
switch and bulbs causing the reversing lamps
to light.
8If the vehicle in question has automatic
transmission (AT), the circuit differs in that the
“live feed” goes from fuse 22 to terminal “F” of
the transmission selector lever position switch
connector X46 (track reference number 773).
When position “R” is selected, terminals “F”
and “G” are connected so that the circuit feed
continues (back to track reference number
496, the “RFS/reversing lamp” circuit) along
the same route described above for manual
transmission models.
