Heating and Air Conditioning
The main difference between the
Climatronic and Climatic systems is the
method used to control air distribution. The
Dual Zone Climatronic system has an
additional fresh air door, which closes at
speeds above 60 mph (97 kph). This
provides constant fresh air flow at different
vehicle speeds.
