REMOVAL
Disconnect the battery.
Remove :
- the steering wheel bolt,
- the steering wheel after first placing the wheels
in a straight line.
ATTENTION: Follow the recommendations contai-
ned in section 88 relating to the AIR BAG system.
Remove :
- the steering wheel half-shell cowlings,Using adhesive tape, immobilise the rotor for the
air bag switch.
Remove :
- the ashtray,
- the two screws securing the heater control pa-
nel,
- the fuse holder plate securing screws (five
screws),

In the passenger compartment
Remove :
- the air distribution unit,
- the heater unit radiator.REFITTING
Check :
- that the wiring is correctly routed behind the
dashboard,
- that the air ducts are correctly secured to pre-
vent noises developing.
Change the steering wheel bolt (pre-bonded bolt,
tightening torque : 4.5 daN.m).
IMPORTANT : Before reconnecting the AIR BAG
cushion it is necessary to apply the air bag system
operational check procedure :
• Check that the AIR BAG warning light on the
instrument panel is illuminated when the igni-
tion is switched on.
• Connect an inert ignition unit to the AIR BAG
cushion connector and check that the warning
light extinguishes.
• Switch off the ignition, connect the AIR BAG
cushion in place of the inert ignition unit and
secure the cushion on to the steering wheel.
• Switch on the ignition, check that the air bag
warning light illuminates for three seconds
when the ignition is switched on and then ex-
tinguishes and remains extinguished.
If the warning light does not operate as indicated
above, please consult section 88 of the workshop
repair manual.

Check that 12 volts is present on track 1 of the clutch connector.
Is 12 volts present?
Check the condition of the compressor earth.
Is the compressor earth in good condition?
YES Check the continuity and absence of short circuits of the electrical
wiring between the clutch and the compressor.
If the electrical wiring is faulty, repair it.
If the electrical wiring is in good condition, change the compressor.
NO Repair the compressor earth.
Check the continuity and absence of short circuits of the electrical wiring
between track 1 of the clutch and tracks 2 and 17 of the air conditioning control
unit 30-way connector.
Repair the electrical wiring if necessary.
For petrol vehicles:
Use the XR25 fiche which corresponds to the vehicle.
With the engine running, operate the AC then check on the XR25 fiche whether
the "Compression authorised or prohibited" status bargraph is illuminated.
Is the bargraph illuminated?
YES Check and repair the electrical wiring.
NO Refer to Left-hand bargraph 4 illuminated, cont 2.

With the engine running, operate the AC then check on the XR25 fiche whether the " AC authorisation"
status bargraph is illuminated.
Is the bargraph illuminated?
There is a problem at the injection end.
Refer to the injection fault finding procedure which corresponds to the vehicle.
Check the continuity and absence of short circuits of the electrical wiring.
Repair if necessary.
Check that 12 volts is present on tracks 2 and 17 of the air conditioning control
unit 30-way connector.
Is 12 volts present?
YES There is a problem at the injection end.
Refer to the injection fault finding procedure which corresponds to
the vehicle.
NO Check whether the evaporator temperature sensor is in place.
Check its resistance: disconnect the evaporator temperature sensor
and measure the resistance at its terminals. The resistance measured
should be between 90 ohms and 13.7 kohms.
If the evaporator temperature sensor is in good condition, change
the air conditioning control unit.
If the evaporator temperature sensor is not in good condition,
change it.
