WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all SERVICE PRECAUTIONS and DISABLING &
ACTIVATING AIR BAG SYSTEM procedures in AIR BAG SYSTEM SAFETY

DESCRIPTION
These systems are a blend-air type. Outside air enters
through a cowl at base of the windshield and flows through a plenum
chamber into blower housing. Airflow velocity is controlled by blower
speed selector switch. Air flows across evaporator and is directed by
a blend-air door to go either through or by-pass the heater core.
On Dakota and Durango, temperature control cable operates
blend-air door and allows immediate control of outlet air temperature.
It also controls operation of recirculation door. On Ram Pickup,
temperature is regulated by a blend-air servo motor controlled from
A/C-heater control panel rotary temperature dial. On all models, mode
selector switch controls vacuum-operated doors to direct conditioned
air to selected outlets.
Durango may also be equipped with an optional rear A/C unit.
The rear A/C unit consists of a blower motor and evaporator. It will
only operate while the front A/C is on. The optional rear A/C-heater
unit is controlled using fan and temperature switches.
