WARNING: This page is about a different car, the 1999 Dodge Pickup, 1999 Dodge Durango, 1999 Dodge Dakota, and 1999 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

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.
