through a ducted vent on top of the vehicle front wing
to the blower motor (volute) housing (4). The blower
motor (10) can be used to boost the air flow into the
distribution unit. The air flap (13) controls the supply of
heated or ambient air from the heater unit into a
plenum chamber integeral with the vehicle fascia. Two
flaps in the plenum chamber (heater duct) distribute
the air flow to either the footwell vents or windscreen
demister vents as shown.
The heater matrix (3), located in the distribution unit
