2003 FORD EXPEDITION Owners Manual

Automatic operation
Press AUTO and select the desired
temperature. The system will either
heat or cool the vehicle to achieve
the selected temperature. The
system will automatically determine
fan speed, airflow location and
whether outside or recirculated air
is required.
When in automatic operation and weather conditions require heat, air
will be sent to the floor ducts. However, until the engine is warmed, the
fan speed will operate at low speed and airflow will be directed to the
windshield defroster ducts. Upon engine warm up, the system will
automatically direct airflow to the floor ducts and operate the required
fan speed to achieve the selected temperature.
If unusual conditions exist (i.e., window fogging, etc.), the manual
overrides allow you to select airflow locations and the fan speed. To
return to automatic operation, press AUTO.
Temperature selection
To control the temperature, select
the desired temperature by pressing
the temperature controls.

Temperature conversion
Press the Fahrenheit/Celsius (F/C)
control to switch between
Fahrenheit and Celsius temperature
on the EATC display. The
temperature in Celsius will be
displayed in half-degree increments.
The English/Metric (E/M) control on
the message center (if equipped)
and the trip computer will not
change the temperature display.
Displaying outside temperature
Press EXT to display the outside air
temperature. It will be displayed
until EXT is pressed again.
If the interior temperature or fan speed are adjusted or a manual
override is selected while the outside temperature is being displayed, the
new temperature, fan speed, or override control will appear in the
display window for four seconds and the outside temperature will return
to the display window.
The outside temperature reading is most accurate when the vehicle is
moving. Higher readings may be displayed when the vehicle is not
moving. Due to locations, the outside temperature readings from the
vehicle may not agree with those obtained from radio station broadcasts.

Fan speed ()
When in automatic operation, fan
speed operates as necessary to
achieve the selected temperature. If
desired, the fan speed can be
adjusted manually through the use
of the fan speed control. When the
fan speed is controlled while in
automatic operation, the AUTO
indicator will remain lit and the
system will remain in automatic operation. To return to automatic fan
operation, press AUTO.
A/C control
Used to manually enable or disable
the air conditioning in all modes
except Defrost and Floor & Defrost.
The A/C will only function if the
outside temperature is above 2°C
(35°F). In Defrost and Floor &
Defrost, the A/C will operate
automatically if the outside
temperature is above 2°C (35°F).
The A/C indicator will not be lit.
In automatic operation, the air conditioning operates as necessary to
achieve the selected temperature and the A/C indicator will be lit. If
desired, the air conditioning can be controlled manually through the use
of the A/C control. When the air conditioning is controlled while in
automatic operation, the AUTO indicator will remain lit and the system
will remain in automatic operation. To return to automatic air
conditioning operation, press AUTO.
Since the air conditioner removes moisture from the air, it is considered
normal operation if clear water drips on the ground under the air
conditioner drain.

Recirculation control
Used to manually enable or disable
the operation of recirculated air in
all modes except Defrost. When the
air conditioning is operating,
recirculated air helps to reduce the
amount of time required to cool the
inside of the vehicle. Recirculated
air will reduce undesirable odors
from entering the vehicle.
The recirculation control cannot be selected in Defrost as interior
fogging may occur. To reduce the risk of fogging while in Floor &
Defrost, the recirculation control can be enabled for approximately 4
minutes and the recirculated air indicator will be lit. After approximately
4 minutes of recirculated air operation while in Floor & Defrost, the
EATC will automatically disable the recirculated air and the recirculated
air indicator will not be lit.
In automatic operation, recirculated air operates automatically as
necessary to achieve the selected temperature. If desired, the
recirculated air can be controlled manually through the use of the
recirculated air control. When the recirculated air is controlled while in
automatic operation, the AUTO indicator will remain lit and the system
will remain in automatic operation. To return to automatic recirculated
air, press AUTO.
Under cold or damp conditions, do not leave the climate control system
in recirculated air for extended periods of time as this may cause interior
fogging of the windows.

Manual override controls
The manual override controls allow you to determine where airflow is
directed. To return to full automatic control, press AUTO.
The A/C compressor will only function if the outside temperature is
above approximately 2°C (35°F).
•OFF - Outside air is shut out and the fan will not operate. This mode
will reduce undesirable odors from entering the vehicle but may
increase the possibility of interior window fogging.
•
(Panel) - Distributes outside or recirculated air through the
instrument panel registers. The system will allow some airflow through
the floor ducts.
•
(Panel & Floor) - Distributes outside or recirculated air through
the instrument panel registers and the floor ducts and side window
demisters. The air distributed through the floor ducts will be slightly
warmer than that sent to the instrument panel registers.
•
(Floor) - Distributes outside or recirculated air through the floor
ducts and side window demisters.
•
(Floor & Defrost) - Distributes outside or recirculated air through
the floor ducts, windshield defroster ducts and the side window
demisters. The air distributed through the floor ducts will be slightly
warmer than that sent to the windshield defroster ducts and the side
window demisters.
•
(Defrost) - Distributes outside air through the windshield
defroster ducts and the side window demisters. However, the A/C
indicator will not be lit. This mode will clear ice and fog from the
windshield. The system will allow some airflow through the floor
ducts.

Operating tips
•To reduce fogging in humid weather conditions, unless in Defrost and
Floor & Defrost, press the A/C control before driving as the air
conditioning removes moisture form the air.
•To reduce humidity buildup inside the vehicle in warm weather
conditions, don’t drive with the climate control system in the OFF
position.
•To reduce humidity buildup inside the vehicle in cold weather
conditions, don’t drive with the climate control system in the
recirculation mode or OFF mode.
•Remove any snow, ice or leaves from the exterior base of the
windshield.
•To increase the efficiency of the A/C, drive with the windows slightly
open for 2–3 minutes after start up or until the vehicle has been
“aired out.”
•Do not place objects under the front seat or over the defroster ducts.
They may reduce visibility, fall into the ducts, or degrade the
performance of your climate control system.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or sudden stop.
AUXILIARY CLIMATE CONTROLS
The auxiliary climate control feature
provides increased capacity to
quickly heat or cool the vehicle.
Auxiliary climate controls are
located in the first row overhead
console
Climate Controls

and in the floor console on the back
of the front row console.
The auxiliary climate control system is dependent on the main climate
control system. If the main climate control system is in the Off position,
the auxiliary climate control will not operate. If the main climate control
system is on, the auxiliary air will not be cooled unless the air
conditioning is functioning on the main climate control system.
The auxiliary unit can be controlled either by the front seat using
the front auxiliary control or by the rear seat passenger(s) using
the rear auxiliary control but not both. To control the auxiliary
unit using the rear control, the front control must be in the
REAR position.
FAN SPEED CONTROL
Controls the fan speed in the rear of
the vehicle.
TEMPERATURE CONTROL
Controls the temperature of the
airflow in the rear of the vehicle.
