Climate control unit
DISMOUNTING
Disconnect the battery.
Dismount :
- 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.
Dismoun t, 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.
REMOU NT I NG
Perform the dismounting operations in the
reverse order. Tighten t he attachment screws of the c li-
mate control unit on the climate control box, in
the sequence shown in drawing (1,2,3 ).

DISMOUNTIN G
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;

- climate control box gasket;
- engine air filter;
- climate control box central part from
the eight attachment screws;
- attachment screws of the climate c on-
trol unit and release the climate control blower
after disconnecting it.
- RACV attachment screws (1) on the
climate control box.
Clamp t he 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 c ool-
ing fluid. Dismou nt then:
- acoustic plate ( 2);
- mixing a nd distribution fl aps control
cables attached on RACV. Release RACV (3).
REMOU NT I NG
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 t he air ducts.
The require d tightening moment of t he
RACV attachment screws (1) on the climate
control box is of 0,6 daNm.

Operating principle
The climate control assembly is enabling outside air penetration in the vehicle climate control
unit.
Climate controls:
A – air temperature adjustment
B – air distribution in the cockpit
C – air quantity adjustment in cockpit
Air temperature adjustment
Control knob (A) is enabling the obt aining of t he de sired tempera ture in t he cockpit. By
turning to the right the knob (A), the air temperature is increasing.
Air distribution in the cockpit
Ai r distribution in the cockpit is obtained by means of rotating t he knob (B) in the desired
position.
Position
Airflow is directed towards the dashboard air vents.
Position
Airflow is directed towards all dashboard air vents and passengers l egs.
Position
Airflow is directed towards passengers legs.
Position
Airflow is directed between all a ir vents, front side windows defrosting vents, windscreen
defrosting vent and passenger legs.
Position
Entire airflow is directed towards windscreen and side windows defrosting air vents. For a
more substantial efficiency, close the dashboard air vents.
