FORD EXPLORER 2002 3.G Service Manual

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 bar graph to indicate manual
fan operation and relative speed.
When the fan is adjusted in the AUTO mode, the AUTO indicator will
remain lit and the system will remain in auto operation.
To return to automatic fan operation, press AUTO. The fan icon and bars
will disappear from the display, and the DEATC system will return to full
automatic operation.
²A/C control
A/C(air conditioning) Ð Used to manually enable or disable the
operation of the air conditioning in all modes except
and.In
all modes, the air conditioning will only function if the outside
temperature is about 6ÉC (43ÉF) or higher. When manual A/C is selected
(ON) the indicator will be lit. When manual A/C is selected (OFF) the
indicator will not be lit.

Inand, if the outside temperature is about 6ÉC (43ÉF) or
higher, the air conditioner will automatically dehumidify the air to reduce
fogging. However, the A/C indicator will be off and the A/C override
control cannot be selected.
The air conditioning compressor can operate in all modes except OFF.
However, the air conditioning will only function if the outside
temperature is about 6ÉC (43ÉF) 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. However, the A/C indicator will not be lit. If A/C is selected
when in AUTO operation, the DEATC system will be disabled and you
will return to manual operation with the A/C indicator lit.
To return to automatic A/C operation, press AUTO.
²Recirculation control
(air recirculation) Ð Used to manually enable or disable the
operation of the recirculated air operation in all modes except
and. 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 DEATC system to automatically control the
selection of outside or recirculated air.
The recirculation control cannot be selected in
or, as interior
fogging may occur.

When AUTO is selected, the recirculated air feature operates automatically
for existing conditions. However, the air recirculation indicator will not be
lit. If the recirculated air is selected while in AUTO operation, the DEATC
system will be disabled and you will return to manual operation with the
recirculated air indicator lit and with the A/C operating.
To return to automatic recirculated air operation, press AUTO.
Do not leave the DEATC 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.
Manual override controls
The manual override controls allow you to manually determine where
airflow is directed. To return to fully automatic control, press AUTO.
When a manual airflow override control is selected, the DEATC system
will turn off the AUTO indicator and display the indicators of all
operating override controls. More than one override control indicator
may turn on when an override control is selected.
²Airflow direction control
(panel) Ð Distributes air through the instrument panel registers and
the center console registers.
(panel/floor) Ð Distributes air through the instrument panel
registers, the front seat floor ducts and the center console registers. For
added customer comfort, the air distributed through the floor ducts may
be slightly warmer than the air sent to the instrument panel registers.
(floor) Ð Distributes air through the front seat floor ducts adn the
center console registers. The system will allow some airflow out the

defroster ducts, the demister outlets and the front and rear seat floor
ducts. If the temperature is about 6ÉC (43ÉF) or higher, the air
conditioner will automatically dehumidify the air to reduce fogging. (Note
that the A/C indicator does not illuminate when this mode is selected.)
Recirculation and A/C override controls cannot be selected. For added
customer comfort, the air distributed through the floor ducts may be
slightly warmer than the air sent to the windshield defroster ducts.
(defrost) ÐDistributes outside air through the windshield defroster
ducts, the demister outlets and the center console registers. It can be
used to clear ice or fog from the windshield. If the outside air temperature
is about 6ÉC (43ÉF) or higher, the air conditioner will automatically
dehumidify the air to reduce fogging. (Note that the A/C indicator does
not illuminate when this mode is selected.) Recirculation and A/C override
controls cannot be selected. For added customer comfort, the system will
allow some airflow through the floor ducts in this mode.

to the window.
If the outside temperature is displayed while the DEATC system is in the
OFF mode and the DEATC is turned on, the driver and passenger
temperatures will be displayed for 4 seconds. Following this, the outside
temperature display will return to the 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 locations.
Operating tips
²In humid weather conditions, place the climate control system in
orRbefore driving. This will reduce fogging on your windshield.
Once the windshield has been cleared, operate the climate control
system as desired.
²To reduce humidity buildup inside the vehicle in cold weather
conditions, don't drive with the climate control system in the OFF or
MAX A/C position.
²To reduce humidity buildup inside the vehicle in warm weather
conditions, don't drive with the climate control system in the OFF
position.
²Under normal weather conditions, your vehicle's climate control
system should be left in any position other than MAX A/C or OFF
when the vehicle is parked. This allows the vehicle to ªbreatheº
through the outside air inlet duct.
²Under 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.
²If 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 ªaired outº, operate the climate
control system as desired.
²Remove any snow, ice or leaves from the air intake area at the base of
the windshield.

²Do 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 aide in side window defogging/demisting in cold weather conditions:
1. Select
2. Set the temperature control to full heat
3. Set the fan speed to High
4. Direct the outer panel vents towards the side windows
In order to increase the 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 climate controls (if equipped)
Depending on 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 and second row seating. The auxiliary climate controls are
independent of the main climate control system. If the main climate
control system is in the OFF position, the auxiliary climate controls will
still work. However, the A/C function will not operate unless the A/C
control has been selected on the main climate control system.
Front auxiliary control
The front auxiliary controls are
located in the front overhead
console.
For the rear auxiliary climate controls to function, the front auxiliary
climate control must be set to REAR.
