Heater and A/C control switch
Automatic Manual
1) Overview
3. INTEGRATED INSTRUMENT PANEL SWITCH
It is mounted to the instrument panel and combined with the cooler; which provides cooling and
dehumidification by repeating the cycles of compression -> condensation -> expansion -> evaporation,
and heater; which controls the heating systemically in the course of circulating the coolant heated by the
engine heat to the heater. This allows the driver to maintain the indoor comfortable conditions throughout
the year.

With FATC
Changes in heater and control assembly
Liquid and suction pipe
Liquid and suction pipe route changed due to change of headlamp mounting bracket

6810-00
A/C condenser & receiver drier
It is installed in front of vehicle and condenses vapor
refrigerant into low temperature and high pressure liquid
refrigerant. The receiver drier is built in it.Ambient temperature sensor
It is mounted to the front section of the
vehicle and detects the ambient
temperature to send the voltage value
according to the resistance change to
the heater and A/C control assembly.
Engine ECU
It controls the A/C compressor, electric fan
and PTC heater according to the signal from
the A/C control panel.
Expansion valve
It is mounted to the inlet of the evaporator
core and supplies the appropriate quantity
of refrigerant to the evaporator.
Integrated receiver drier

2) Interior Layout
Sun load sensor
It is mounted to the upper left-
hand of the instrument panel and
detects the sun-load enters to the
interior through the windshield
with a photo diode. Incar sensor
It is mounted to the rear of the
heater and A/C control panel
(with FATC) and detects the
interior air temperature drawn
through the senor inlet.Air conditioner module
It is mounted to inside of the
instrument panel and has the
evaporator core, heater core,
PTC heater and corresponding
actuator and different sensors.
Heater & A/C control assembly
With FATC With MTC
It falls in to two categories; FATC (Full Automatic Temperature Control) and MTC (Manual Temperature
Control), which controls the air conditioning system's operation.

6810-00
Intake sensor
It is mounted to the side of
evaporator core and detects the
temperature of the evaporator
core.Water temperature
sensor
It is mounted to the heater pipe
part and detects the coolant
temperature.
3) Air Conditioner Module Layout
Temp actuator
It changes the air mix door
opening according to the
control command from the
heater and A/C control
assembly.Evaporator core
It cools the surrounding air by
passing through the low-
temperature and low-pressure
refrigerant sprayed from the
expansion valve.
Heater core
It is mounted to the left-hand of
the air conditioner module and
heats the indoor using the heat
of the engine coolant.
Mode actuator
It controls the air outlet damper
to the five directions according
to the control command from
the heater and A/C control
assembly.

Blower motor
It is mounted to the bottom of
the blower box and sends the
air inside of the vehicle. PTC heater
It is mounted to the heater air
outlet in the heater module
and warms the air from the
heater to the air vent.
Intake actuator
It changes the air source selection
mode according to the control
command from the heater and A/C
control assembly.A/C filter
It is mounted to the top of the
blower motor and filters the air
before it is discharged through
the duct.
MOS module
It controls the rotation speed of
the blower motor by receiving the
fan speed control signal from the
heater and A/C control assembly.
