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 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 left-hand knob controls air ventilation at four different speeds by means of an electrical control; two versions are available: a three-speed version and a four speed version.The air recirculation lever and the air conditioner compressor pushbutton are located in the lower control area.The control unit is lit with the side lights on.The fan circuit is protected by a specific fuse and controlled by the passenger compartment air fan relay located in the engine bay junction unit.The fan can only be activated with the key ON.
The passenger compartment air fan circuit is controlled by relay R8 in engine compartment junction unit B01.The power supply to the relay is received from the battery at pin 1 of connector A of B01 protected by fuse F8 while the coil is excited by an ignition-controlled supply (INT/A) via a line protected by fuse F31 of under-dashboard junction unit B02.When climate contol system button H81 (pin 1 of connector B) is pressed, relay R8 is excited and sends a direct supply to fan N85 which operates at different speeds according to the load applied to control knob H81 (supplied at pin 1 of connector A of fuse line F31).When the selector is operated, the number of resistances applied (voltage divider) is altered to alter the speed of fan N85.Antimist thermostat N8 on the evaporator in the duct/distributor unit inhibits the operation of the air conditioner compressor if the evaporator freezes.In positions 1 to 4, selector H81 closes an internal contact that enables the activation of an air conditioner compressor.The symbols of the control unit are lit with the side lights on by lights G45 (A, B, C) suppolied by a line protected by fuse F51 of under-dashboard junction unit B02.
