2002 FORD THUNDERBIRD air condition

WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle's functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works.If any light remains on after starting the vehicle, have
the respective system inspected immediately.
Check engine
Illuminates briefly to ensure the
system is functional. If it comes on
after the engine is started, one of
the engine's emission control
systems may be malfunctioning. The light may illuminate without a
driveability concern being noted and will not require towing.
Light turns on solid:
Temporary malfunctions may cause your light to illuminate. Examples
are:
²The vehicle has run out of fuel.
²Poor fuel quality or water in the fuel.
²The fuel cap may not have been properly installed and securely
tightened.

DATC automatic operation
Press AUTO and select the desired
temperature. The selected
temperature will appear in the
display window, and an indicator
above the AUTO control will light.
The DATC system will either heat or
cool the vehicle to achieve the
selected temperature. The system
will automatically determine the fan
speed, airflow location and whether outside or recirculated air is
required.
When in AUTO and weather conditions require heat, the DATC directs
the majority of the airflow to the floor area. The system will allow some
airflow out of the defroster, demister outlets and outer instrument panel
registers in order to reduce window fogging. Additionally, if the engine is
not warm enough to provide heat, the fan will operate at a low speed
and the airflow will be directed to the windshield or to the floor. In
approximately 3
1¤2minutes or less, the fan speed will start to increase
and the airflow location will change to the floor area.
When in AUTO mode, the DATC system automatically controls the air
conditioning operation, the fan speed, the airflow direction and
determines whether outside or recirculated air is required. Manual
control of the A/C, air recirculation and fan speed are available in auto
mode.
If unusual conditions exist (i.e. window fogging), the manual override
controls allow you to select airflow locations as necessary. To return to
full automatic control, press the AUTO control.

Temperature conversion
Press the Fahrenheit/Celsius (ÉF ÉC)
control to switch between
Fahrenheit and Celsius temperature
on the DATC display only. The set
point temperatures in Celsius will be
displayed in half-degree increments.
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 speed 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 DATC 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 defrost. In all
modes, the air conditioning will only function if the outside temperature
is about 2ÉC (35ÉF) 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.

In defrost and floor/defrost mode, if the outside temperature is about 2ÉC
(35ÉF) or higher, the air conditioner will automatically dehumidify the air
to reduce window fogging. However, the A/C indicator will be off and the
A/C override control cannot be selected.
When AUTO is selected, the A/C operates automatically for existing
conditions. With automatic A/C operation, the A/C indicator will be lit if
the outside temperature is about 2ÉC (35ÉF) or higher. You may override
the automatic A/C operation at any time. To manually control the A/C
operation and cancel automatic A/C operation, press the A/C control.
When the A/C is manually controlled in the AUTO mode, the AUTO
indicator will remain 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 defrost.
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 DATC system to automatically control the selection of outside
or recirculated air.
The recirculation control cannot be selected in the defrost mode, as
interior fogging may occur.
In floor and floor/defrost modes, the DATC system will automatically
return to outside air to help reduce window fogging. When the
recirculation air control is selected, the amount of time in manual
recirculated air depends on the ambient temperature.

When AUTO is selected, the recirculated air feature operates
automatically for existing conditions. You may override the automatic
recirculated air operation at any time. To manually control the
recirculated air operation and cancel automatic recirculated air
operation, press the recirculated air control. When the recirculated air is
manually controlled in the AUTO mode, the AUTO indicator light will
remain lit. To return to full automatic recirculated air operation, press
AUTO.
Do not leave the DATC 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 DATC 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.
The air conditioning compressor can operate in all modes except OFF.
However, the air conditioning will only function if the outside
temperature is about 2ÉC (35ÉF) 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.

²Airflow direction control
(panel) Ð Distributes air through the instrument panel.
(panel/floor) Ð Distributes air through the instrument panel and
the front floor ducts. 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 floor ducts. The system
will allow some airflow out the defroster ducts, the demister outlets and
outer instrument panel registers.
(floor/defrost) Ð Distributes air through the windshield defroster
ducts, the demister outlets and the front floor ducts. The system will
allow some airflow out of the outer instrument panel registers. For added
customer comfort, the air distributed through the floor ducts may be
slightly warmer than the air sent to the windshield defroster ducts. If the
outside temperature is about 2ÉC (35ÉF) or higher, the air conditioner
will automatically dehumidify the air to reduce window fogging. (Note
that the A/C indicator does not illuminate when this mode is selected.)
Recirculation and A/C override controls can be selected.
(defrost) Ð Distributes outside air through the windshield
defroster ducts and the demister outlets. It can be used to clear ice or
fog from the windshield. The system will allow some airflow out of the
outer instrument panel registers. If the outside temperature is about 2ÉC
(35ÉF) or higher, the air conditioner will automatically dehumidify the air
to reduce window fogging. Recirculation and A/C override controls
cannot be selected.Note that the A/C indicator does not illuminate
when this mode is selected.
²Turn DATC off
OFF-Outside air is kept out. The fan, heating and air conditioning will
not operate. The outside temperature will still display when selected
with the ignition in the RUN position.
Electric window heaters
(heated wiper rest) Ð Located at the base of the windshield, this
feature heats the front glass area below the area heated by the front
defroster where the windshield wipers sit in their parked position. When
activated, the feature keeps the wiper blades warm and reduces the
chance of ice build up on the blades. The indicator will light when the
feature is in operation.

With the ignition in RUN and the engine running, the feature will be
automatically enabled if the temperature is below 5ÉC (40ÉF). The
feature can be manually selected or deselected at any time. However, the
automatic feature will be enabled each time the engine is started.
In cold, dry conditions where wet snow or ice is not present it is
acceptable to manually deselect the operation of this feature.
The feature will run continuously unless a low battery condition is
detected, or unless the feature is manually deselected, and will only
activate when the vehicle engine is running (to prevent excessive drain
of the vehicle battery).
R(rear window defroster) Ð Refer toRear Window Defroster.
Displaying outside temperature
Press EXT to display the outside air temperature. It will remain selected
until the EXT control is pressed again.
If the driver or passenger temperature or the fan speed is changed, or
the AUTO or
modes selected while the outside temperature is
displayed, the driver and passenger temperature display will be displayed
for 4 seconds. Following this, the outside temperature display will return
to the window.
If the outside temperature is displayed while the DATC system is in the
OFF mode and the DATC 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 may not agree with temperatures given on the
radio due to differences in vehicle and station locations.

Operating tips
²In humid weather, select
andRbefore driving. This will
reduce fogging on your windshield. After a few minutes, select any
desired position.
²To prevent humidity buildup inside the vehicle, don't drive with the
climate control system in the OFF position.
²DO NOT leave the DATC system in recirculated air mode for extended
periods of time while the system is in a heating mode or in cold or
damp conditions as this may cause interior fogging of the front, side
and rear windows.
²Do not place objects under the front seat that will interfere with the
airflow.
²Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
²If your vehicle has been parked with the windows closed during hot
weather, the air conditioner will do a much faster job of cooling if you
drive for two or three minutes with the windows open. This will force
most of the hot, stale air out of the vehicle. Then operate the air
conditioner as you would normally.
²If the air conditioner works well with the recirculation feature on, but
not in the outside air mode, this may indicate that the cabin air filter
needs to be replaced.
²Do not place objects over the defroster outlets. These objects can
block airflow and reduce your ability to see through your windshield.
Also, avoid placing small objects on top of your instrument panel.
These objects can fall down into the defroster outlets and block
airflow and possibly damage your climate control system.
