DESCRIPTION

Foreword

The manually-operated climate control system makes it possible to completely control the air admitted to the car: in fact, it cools the air in hot weather but also dehumidifies and recirculates it.

The system may be considered as split into two sections:

• unit comprising the air duct and distributor;
• closed loop system which generates cold.

DUCTING/DISTRIBUTOR UNIT

1. Upper distribution port
2. Mixing port
3. Ducting unit
4. Outside air flow adjustment and recirculation port
5. Outside air flow adjustment and recirculation port control motor
6. Electric fan resistance
7. Electric fan
8. 1st fan speed relay
9. Electric fan relay
10. Evaporator
11. Heater radiator
12. Lower distribution port
13. Heater-distributor unit
14. Radiator adjustment tap
15. Lower distribution port control cable
16. Mixing port control cable
17. Upper distribution port control cable

NOTE: While the cooling system located in the passenger compartment is identical to that of cars with left-hand drive with regard to the location of the components, the ducting/distributor unit is different as described below.

NOTE:

Differences for version with heater

• the evaporator is not present;
• the wiring is specific: it is without the two relays (for further details see Group 55 - ELECTRIC SYSTEM DIAGNOSIS in base manual);
• the front box (upper and lower) differs in shape;
• the shape and ohm rating of the electric fan resistance differs (for further details see Group 55 - ELECTRIC SYSTEM DIAGNOSIS in base manual);

N.B. The servicing procedures described below refer to the version with air conditioner: for the version with heater, omit the operations involving the components that are not present.
