EMTC - Overview

Climate Control System - Vehicles With: EMTC - Overview 

The climate control system consist of the following components:

• Air Conditioning(A/C) compressor - Externally Controlled Variable Displacement Compressor (EVDC)
• A/C compressor clutch and clutch field coil
• AAT sensor
• Air Conditioning(A/C) pressure transducer
• Blower motor
• Blower motor speed control
• Condenser core on 2.0L/3.5L GTDI equipped vehicles
• Condenser core with integrated receiver drier on 3.5L/3.7L Ti-VCT equipped vehicles
• Connecting refrigerant lines
• Evaporator core (part of the heater core and evaporator core housing)
• Evaporator temperature sensor (part of the heater core and evaporator core housing)
• FCIM
• FDIM
• Heating Ventilation Air Conditioning(HVAC) control module
• Heater core
• Heater core and evaporator core housing
• In-vehicle temperature and humidity sensor
• Mode door actuator - air inlet
• Mode door actuator - defrost/panel/floor
• Receiver drier on 2.0L/3.5L GTDI equipped vehicles
• Temperature blend door actuator
• TXV

The Electronic Manual Temperature Control(EMTC) system heats or cools the vehicle interior depending on the HVAC control panel selection. The FCIM provides the interface for the vehicle occupants to control the climate control system. When selections are made, the FCIM communicates the selections to the HVAC control module through the vehicle module communication network.

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