The vehicle climate control system
involves a duct/distributor unit with a heater, controlled via two
knobs in the dashboard: each knob carries out a dual function: one
with the outer ring nut, one with the actual knob in the centre:
- the ring nut for the left knob mechanically controls the
mixture flap between hot and cold air; the inner knob electrically
controls the ventilation of the air at four different speeds;
- the opening of the flaps which adjust the distribution
of the air flows; the inner knob mechanically controls the engagement
of the recirculation function.
