FORD EXCURSION 2004 1.G Repair Manual

Turning the EATC on
Press AUTO, any of the override controls or the fan speed control. The
EATC will only operate when the vehicle is running.
Turning the EATC system off
Press OFF.
Automatic operation
Press AUTO and select the desired temperature. The selected
temperature and the word AUTO will appear in the display window. The
EATC system will either heat or cool to achieve the selected
temperature. The system will automatically determine fan speed, airflow
location and if outside air or recirculated air is required.
When in AUTO and weather conditions require heat, the EATC system
directs the majority of the airflow to the floor area. The system will allow
some airflow through the windshield defroster ducts to reduce window
fogging. However, if the engine is not warm enough to provide heat, the
fan will be at a low speed and the airflow will be directed to the
windshield. In approximately 3
12minutes or less, the fan speed will start
to increase and the airflow location will change to the floor.
If unusual conditions exist (i.e.-window fogging, etc.), the manual
override controls allow you to select airflow locations and the fan control
allows you to adjust fan speed as necessary.

Fan speed ()
When AUTO is pressed, fan speed is adjusted automatically for existing
conditions. You can override fan speed at any time. To control fan speed
manually, press the fan control to cancel the automatic fan speed
operation. Press the control up for higher fan speed or down for lower
fan speed. The display will show (
) and a a bar graph to indicate
manual fan speed operation and relative speed.
To return to automatic fan operation, press AUTO.
A/C control
Used to manually enable or disable
the operation of the air conditioning
in all modes except
.Inall
modes, the air conditioning will only
function if the outside temperature
is about 6°C (43°F) or higher. When
manual A/C is selected, A/C will be
displayed in the display window.
In
, if the outside temperature
is about 6°C (43°F) or higher, the air conditioner will automatically
dehumidify the air to reduce window fogging. However, A/C will not be
displayed in the display window.
The air conditioning compressor can operate in all modes except OFF.
However, the air conditioning will only function if the outside
temperature is about 6°C (43°F) or higher.
Since the air conditioner removes considerable moisture from the air
during operation, it is normal if clear water drips on the ground under
the air conditioner drain while the system is working and even after you
have stopped the vehicle.

When AUTO is selected, the A/C operates automatically for existing
conditions and A/C will be displayed in the display window. If A/C is
selected while in AUTO operation, A/C will not be displayed in the
display window and the EATC system will remain in AUTO operation.
However, the EATC system will operate without the use of the air
conditioning. To return to automatic air conditioning operation, press
AUTO.
Recirculation control
Used to manually enable or disable
the operation of the recirculated air
operation in all modes except
.
The use of recirculated air when the
air conditioning is operating helps to
reduce the amount of time to cool
down the interior of the vehicle in
very hot conditions. Recirculated air
may also help to keep undesired
outside odors from reaching the vehicle interior. It is recommended to
allow the EATC system to automatically control the selection of outside
or recirculated air.
The recirculation control cannot be selected in the
, as interior
fogging may occur.
When AUTO is selected, the recirculated air feature operates
automatically for existing conditions. However,
will not be
displayed in the display window. If
is pressed again,will
not be displayed in the display window and the EATC system will remain
in AUTO operation. To return to automatic recirculated air operation,
press AUTO.
Do not leave the EATC system in recirculated air operation for extended
periods of time while the system is in a heating mode or in cold/damp
conditions as this may cause interior fogging of the front, side and rear
windows.

Turning the EATC off
OFF — Outside air is shut out. The fan, heating, and air conditioning will
not operate. The outside temperature will still display when selected
with the ignition in the ON position.
Displaying outside temperature
Press EXT TEMP to display the
outside air temperature. It will be
displayed until EXT TEMP is
pressed again.
If the temperature or fan speed is adjusted or if AUTO or
modes
are selected while the outside temperature is being displayed, the vehicle
interior temperature will be displayed for four seconds. After four
seconds have passed, the outside temperature will return to the display
window.
If the outside temperature is displayed while the EATC system is in the
OFF mode and then is turned on, 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 obtained when the vehicle is not
moving. The readings that you get may not agree with temperatures
given on the radio due to differences in vehicle and station location.
Operating tips
•In humid weather conditions, place the climate control system in
or rear defrost before driving. This will reduce fogging on your
windshield. Once the windshield has been cleared, operate the climate
control system as desired.
•To reduce humidity buildup inside the vehicle in cold weather
conditions, don’t drive with the climate control system in the OFF
position or
.
Climate Controls

•To reduce humidity buildup inside the vehicle in warm weather
conditions, don’t drive with the climate control system in the OFF
position.
•Under normal weather conditions, your vehicle’s climate control
system should be left in any position other than OFF or
when
the vehicle is parked. This allows the vehicle to “breathe” through the
outside air inlet duct.
•Under snowy or dirty weather conditions, your vehicle’s climate
control system should be left in the OFF position when the vehicle is
parked. This allows the climate control system to be free from
contamination of outside pollutants.
•If your vehicle has been parked with the windows closed during warm
weather conditions, the air conditioner will perform more efficiently in
cooling the vehicle if driven for two or three minutes with the
windows open. This will force most of the hot, stale air out of the
vehicle. Once the vehicle has been “aired out”, operate the climate
control system as desired.
•Don’t put objects under the front seat that will interfere with the
airflow to the rear seats.
•Remove any snow, ice or leaves from the air intake area at the area
(at the bottom of the windshield and underneath the hood).
•Do not place objects over the defroster outlets. These objects can
block airflow and reduce your ability to see through your windshield.
Avoid placing small objects on top of the instrument panel. These
objects may fall down into the defroster outlets and block airflow, in
addition to damaging the climate control system.
To aid in side window defogging/demisting in cold weather conditions:
1. Select
2. Set the temperature control to full heat
3. Select A/C
4. Set the fan speed to HI
5. Direct the outer panel vents towards to side windows
6. To increase airflow to the outer panel vents, close the central panel
vents.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or sudden stop.

AUXILIARY A/C-HEATER CONTROLS (IF EQUIPPED)
Depending upon the equipment package of your vehicle, your vehicle
may be equipped with auxiliary climate controls. The auxiliary climate
control feature provides increased capacity to quickly heat or cool the
vehicle.
Your auxiliary climate controls are located in the overhead console of the
first row seating and in the headliner of the second row seating. The
auxiliary climate controls are dependent on the main climate control
system. If the main climate control system is in the OFF position, the
auxiliary climate controls will not work. In addition, if the main climate
control system is operating at a full cool temperature (MAX A/C
or
), the auxiliary temperature control becomes non-functional and
also operates at a full cool temperature.
The auxiliary unit can be controlled either by the front seat using the
front auxiliary control or by the rear seat passenger 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.
