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.

If it is changed, the compressor is supplied filled
with oil.
Position the compressor the correct way round
(filler plug facing upwards).
Tighten the three bolts (C) (Tightening torque:
2.1 daN.m).
Fit the strut retaining bolts (B).
Refit the two R134a coolant pipes (A) on the
compressor (Tightening torque:

cuit using the filling equipment.
NOTE: when refitting the connecting pipes on the
compressor, it is essential to fit all the bolts, then
bring them into contact before torque tightening
them. The aim is to ensure that the pipe is positio-
ned correctly so that it is not damaged at the cut
off (1).

•
RECIRCULATION MOTOR
It is only possible to gain access to the recircula-
tion motor following removal of the air blower
unit (refer to the relevant section) and therefore
the evaporator assembly. •
PRESSURE SENSOR
The pressure sensor (1) is located next to the
condenser on the pressure relief valve-
dehydration canister high pressure pipe.
