The vehicle climate is controlled via a duct/distributor unit with heater and 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.
