Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) - Overview

The climate control system consist of the following components:

• Air Conditioning (A/C) compressor - fixed displacement
• A/C pressure transducer
• Ambient Air Temperature (AAT) sensor
• Air inlet door actuator
• Blower motor
• Blower motor resistor
• Blower switch (fan speed control switch)
• Compressor clutch assembly
• Condenser
• Connecting refrigerant lines
• Door actuator - air inlet
• Door actuator - defrost/panel/floor
• Door actuator - temperature
• Evaporator core
• Evaporator temperature sensor
• Heater core
• Heater core and evaporator core housing
• Heating Ventilation Air Conditioning (HVAC) control module
• Receiver drier desiccant bag
• Thermostatic Expansion Valve (TXV)

The Electronic Manual Temperature Control (EMTC) system heats or cools the vehicle interior depending on the HVAC control panel selection.

• The control panel selection determines heating or cooling, air distribution and enables blower motor operation.
• The blower switch (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 or to turn the system off.
• During A/C operation, the system reduces the relative humidity of the air inside the vehicle.
