Heating And Air Conditioning - Description

DESCRIPTION

This vehicle can be equipped with a Manual Temperature Control (MTC) or an Automatic Temperature Control (ATC) single zone Heating, Ventilation and Air Conditioning (HVAC) system, or a MTC heating and ventilation only system.






NOTE: Manual Temperature Control (MTC) shown. Automatic Temperature Control (ATC) similar.

All vehicles use an HVAC housing (1) that combines heating, ventilating and A/C capabilities (when equipped) into a single housing, located behind the instrument panel. Based upon the mode selected, conditioned air can exit the HVAC housing through one, or a combination of, the panel (2), defrost (3) and floor (4 and 5) outlets. Once the conditioned air exits the HVAC housing, it is further directed through molded plastic ducts to the air outlets within the vehicle interior.

When equipped, the A/C system uses a clutch type A/C compressor, R-134a refrigerant and an A/C expansion valve to meter the flow of refrigerant to the A/C evaporator.

To maintain the performance level of the HVAC system, the engine cooling system must be properly maintained. The use of a bug screen is not recommended. Any obstructions in front of the radiator or A/C condenser will reduce the performance of the A/C and engine cooling systems. The engine cooling system includes the radiator, thermostat, radiator hoses and the engine coolant pump. See Cooling system for more information.
