Climate Control System - Vehicles With: Electronic Automatic Temperature Control (EATC) - Overview

Overview

The climate control system consists of the following components:

• A/C compressor
• A/C compressor clutch assembly
• A/C condenser core
• A/C evaporator core
• Receiver/drier
• Connecting refrigerant lines
• Thermostatic Expansion Valve (TXV)
• Heater core and evaporator core housing
• HVAC control module
• IPC
• Ambient air temperature (AAT) sensor
• Evaporator temperature sensor
• Center register air discharge temperature sensor
• Footwell air discharge temperature sensor
• In-vehicle temperature sensor
• Sunload sensor
• Air distribution door actuator
• Air inlet door actuator
• Temperature door actuator
• Blower motor
• Blower motor speed control

The EATC system heats or cools the vehicle interior depending on the HVAC control panel selection.

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