Operating principle
AIR TEMPERATURE CONTROL
The knob (A) is controlling the flaps for cold/warm air.
By rotating to the right the (A) knob, the air temperature is increasing.
Cold air
Warm air
The heating radiator is not having any valve and is permanently supplied. The flap controlled
by the cable (1) is ensuring the operation of the cold air re-heating system.

AIR REPARTITION CONTROL
The knob (B) is controlling air repartition flaps
(1).
Position
Airflow is directed towards the dashboard
side air vents.
Each air vent has three adjustments:
- open or closed;
- upward or downward directed
- left or right directed
Position
Airflow is directed towards all dashboard air
vents and towards passengers legs.
Position
Airflow is directed towards passengers legs.
Operating principle
Position
Airflow is distributed between all air vents,
defogging air vents of front side windows,
windscreen defogging air vent and passengers
legs.
Position
For a better efficiency, the dashboard air
vents are to be closed.
The whole airflow is directed towards de-
fogging strip and air vents of the front side win-
dows.
Position
Entire cockpit is outside isolated and out-
side air penetration is not allowed, climate con-
trol blower operation being stopped.
AIR QUANTITY CONTROL
The airflow rate cycled in the cockpit is
settled by the (C) knob position, corresponding
to the four speeds of the climate control blower.
The more speed step is bigger the more airflow
is bigger.
REMARK
For a better efficiency of the windscreen
defrosting or defogging, the (C) knob must
be placed on the last position.
In order to stop the climate control blower
operation, rotate the knob on “0” position.

- climate control box protector;
- climate control box gasket
- gas purge vessel;
- engine air filter.
Detach from clips the front wiring from the
central part of the climate control box.
Dismount, then:
- attachment screws of the climate con-
trol unit on the climate control box.
- attachment screws of the central part
of the climate control box.
Disconnect and release the climate control
unit from the climate control box.
REMOUNTING
Perform the dismounting operations in the
reverse order.
Tighten the attachment screws of the cli-
mate control unit on the climate control box, in
the sequence shown in drawing (1,2,3 ).
The required tightening moment of the at-
tachment screws of climate control unit on the
climate control box is of 0,6 daNm.

DISMOUNTING
Disconnect the battery.
Dismount :
- dashboard (see chapter 57 “dash-
board”);
- central console;
- electric windows control connectors;
- front pillars coverings;
- driving post cross beam;
- climate control box protector;
- gas purge vessel;
- climate control box gasket;
- engine air filter;
- climate control box central part from
the eight attachment screws;
- attachment screws of the climate con-
trol unit and release the climate control blower
after disconnecting it.
- RACV attachment screws (1) on the
climate control box.
Clamp the two hoses from the heating ra-
diator by means of the MOT 453 device.
Disconnect then the fast couplings from the
RACV heating radiator, recovering the cool-
ing fluid.
Dismount then:
- acoustic plate (2);
- mixing and distribution flaps control
cables attached on RACV.
Release RACV (3).
REMOUNTING
Perform the dismounting operations in the
reverse order.
Fill up the cooling fluid and perform the cool-
ing circuit purging (see chapter 19 “ Filling –
Purging cooling circuit”).
Check :
- good operation of the flaps cables;
- good attachment of the air ducts.
The required tightening moment of the
RACV attachment screws (1) on the climate
control box is of 0,6 daNm.
