Non regulated air conditioning.
Check the operation of the fan assembly.
Connect the XR25 and enter G22* and G23*
(direct fan assembly control).
Does the fan assembly operate
at low and high speed?
Check the pressure of the coolant circuit.
The fan assembly should be:
- operating for a pressure≥ 10 bars,
- stopped for a pressure≥ 20 bars.
Is this correct?
Check the electrical wiring
between tracks 22 and 23 of the heating and
ventilation computer and the fan assembly.
Repair if necessary.
If the fault persists,
change the fan assembly.
Check that the components which were removed are connected correctly.
Check that the system operates correctly.

REMOVAL
Disconnect the battery.
Drain the R134a coolant circuit using the filling
equipment.
Disconnect the R134a connecting pipes (bolt 1) to
the pressure relief valve.
Install the plugs on the pipes and the pressure re-
lief valve.Remove:
- the windscreen wiper arms,
- the air inlet grille,
- the six plenum chamber closure panel (2) retai-
ning bolts (A) and remove the plenum cham-
ber,
- the evaporator protector in the plenum cham-
ber.
Disconnect the electrical connectors (4) and the
earth leads (5).
Remove the intermediate sleeve (6) between the
evaporator housing and the heater fan assembly.

VALVE HIGH PRESSURE PIPE
REMOVAL
Detach the pipe from its mountings.
Disconnect the pressure sensor connector.
Remove the mounting bolt on the pressure relief
valve.
Fit plugs to the pressure relief valve and the pipe.
Remove the mounting bolt on the dehydration ca-
nister.
Fit plugs to the dehydration canister and the pipe.
Remove the pipe.
REFITTING
Proceed in the reverse order to removal.
Check the condition of the seals and lubricate
them using
P.A.G. SP 10 oil.
When changing a pipe, add 10 ml of SP 10 oil or
when a pipe bursts (rapid leak), add 100 ml.
Create a vacuum, then fill the R134a coolant cir-
cuit using the filling equipment.

REMOVAL
Disconnect the battery.
Remove:
- the windscreen wiper arms,
- the air inlet grille,
- the evaporator protector in the plenum cham-
ber.
Disconnect the evaporator sensor connector and
the air recirculation motor connector.
Free the wiring from its fasteners.
Remove the evaporator sensor.
REFITTING
Proceed in the reverse order to removal.
Ensure that the sensor is correctly positioned on
its seat on the evaporator.

FAN ASSEMBLY SPEED RESISTOR (2)
This is secured to the engine cooling fan support.
•
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.
All work on the pressure sensor can be carried out
without draining the coolant circuit. It is secured
to a "SKRADER" valve.
Tightening torque: 0.8 daN.m.
This pressure sensor is fitted with seal. Check that
it is in good condition on refitting and lubricate it
using
P.A.G. SP 10 oil.
