AIR CONDITIONING

General
The air conditioning system controls the temperature, distribution and volume of air supplied to the vehicle interior to provide a comfortable cabin environment. The system is electronically controlled and features automatic and manual modes of operation, with separate temperature control of the LH and RH air outlets. The automatic modes provide optimum control of the system under most ambient conditions and require no manual intervention. The manual modes allow individual functions of automatic operation to be overridden, to accommodate personal preferences.

The air conditioning system consists of a refrigerant system, a heater assembly and a control system. It also uses the same air Inlet duct and distribution ducts as the Heating and Ventilation system on non air conditioned vehicles.

Fresh or recirculated inlet air flows into the heater assembly from the blower in the air inlet duct. In the heater assembly, the air is cooled and/or heated, depending on the selected cabin temperature and ambient conditions, then directed to selected air outlets.

On vehicles with rear air conditioning, additional cooling is provided by recirculating air through a second evaporator and distributing it to outlets in the roof.
