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.
