Climate Control System - Overview

Overview 

Single Zone Electronic Automatic Temperature Control (EATC) 

The climate control system consists of the following components:

• A/C compressor: Externally Controlled Variable Displacement Compressor (EVDC)
• A/C clutch and field coil
• A/C condenser
• A/C evaporator
• A/C pressure transducer
• Air inlet door actuator
• Ambient air temperature (AAT) sensor
• Blower motor control module
• Cabin air filter
• Climate control assembly (switches)
• Climate control housing
• Connecting refrigerant lines
• Defrost vent door actuator
• Driver side discharge air temperature sensor
• Evaporator temperature sensor
• Footwell vent/register door actuator
• Heater core
• HVAC control module
• Internal Heat Exchanger (IHX) line
• In-vehicle temperature and humidity sensor
• Receiver drier
• Sunload sensor
• Temperature door actuator
• Thermostatic Expansion Valve (TXV)

The single zone EATC system maintains the vehicle's interior temperature by heating and/or cooling the air based on the HVAC control panel selection.

• The control panel selection determines heating or cooling, air distribution and enables blower motor operation.
• The driver may override the automatic mode of operation.
• The fan speed control adjusts the blower motor speed.
• The temperature control setting is the desired cabin air temperature.
• During A/C operation, the system reduces the relative humidity of the air inside the vehicle.
