Description - AIR CONDITIONING - Fiat DUCATO 2.0 16V fino a 02/05
The vehicle climate control system is achieved through the duct/distributor unit and heater.The air conditioning system integrates the heater with the function of producing cold and dehumidified air achieved by switching on the compressor and the cooling system.The climate is controlled by means of three control knobs on the facia:The left-hand knob controls air ventilation at four different speeds by means of an electrical control;the centre knob controls the mechanical warm and cold air mixing flap;the right hand knob controls opening of the flaps that govern air flow distribution mechanically via a cable.The control for different fan speeds is via a resistance partitioner protected against temperature surges by a thermal fuse.A cursor under the knobs on the control unit modulates the recirculation function mechanically via a cable.The control unit is lit with the side lights on.The entire system is protected by dedicated fuses housed in the engine bay and under-facia junction units. Fan activation is governed by a specific relay.The fan can only be activated with the key ON.
Operational Description - AIR CONDITIONING - Fiat DUCATO 2.0 16V fino a 02/05
The climate control system control unit M070 receives an ignition-operated supply at pin 3 along the line protected by fuse F31 located in the engine compartment junction unit B001. When the climate control fan selector H081 is turned to select the first, second or third speed the passenger compartment air fan adjustment resistance O030 receives a reference earth.The remote control switch H022 protects the passenger compartment air fan N085: when the maximum speed is switched on and the high speed remote control switch J041 contact is closed, the passenger compartment air fan remote control switch J022 switches the position of its contact and the passenger compartment air fan N085, initially supplied and protected by the line for fuse F55 located in the junction unit under the dashboard B002 is supplied and protected by the line for fuse F05 located in the engine compartment junction unit B001.When the air conditioning is switched on the climate control system control unit M070 supplies the air conditioning/heater controls light G045. The same control unit receives an earth signal at pin 1.
