Notes:
Air Distribution System
The air distribution system controls air volume,
temperature and direction within the passenger compart-
ment. The system can add or remove heat from the cabin
air and provide ventilation, heating, cooling and defrost
functions.
On 911 Carrera (996)/(997) and Boxster (986)/(987)
models, the water cooled engine allows the use of a
heater core with hot engine coolant to add heat to the
interior. The air distribution housing contains the
evaporator, heater core, blower fan, air control flaps and
their actuators, and passages to various air outlets in the
vehicle.
The air distribution housing mixes fresh (outside) air, recir-
culated air, cooled air and heated air to obtain the desired
interior temperature. A blower distributes this air to the
system outlets.
