FORD TAURUS 2002 4.G Service Manual

The air conditioning compressor can operate in all modes except
and. 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.
²MAX A/C ± Uses recirculated air to cool the vehicle. MAX A/C is
noisier than A/C but more economical and will cool the inside of the
vehicle faster. Airflow will be from the instrument panel registers. This
mode can also be used to prevent undesirable odors from entering the
vehicle.
²A/C ± Uses outside air to cool the vehicle. It is quieter than MAX A/C
but not as economical. Airflow will be from the instrument panel
registers.
²
(Panel) ± Distributes outside air through the instrument panel
registers. However, the air will not be cooled below the outside
temperature because the air conditioning does not operate in this
mode.
²OFF ± Outside air is shut out and the fan will not operate. For short
periods of time only, use this mode to prevent undesirable odors from
entering the vehicle.
²
(Panel and floor) ± Distributes outside air through the
instrument panel registers and the floor ducts. Heating and air
conditioning capabilities are provided in this mode. For added
customer comfort, when the temperature control knob is anywhere in
between the full hot and full cold positions, the air distributed through
the floor ducts will be slightly warmer than the air sent to the
instrument panel registers.
²
(Floor) ± Distributes outside air through the floor ducts.
However, the air will not be cooled below the outside temperature
because the air conditioning does not operate in this mode.
²
(Floor and defrost) ± Distributes outside air through the
windshield defroster ducts and the floor ducts. Heating and air
conditioning capabilities are provided in this mode. For added
customer comfort, the air distributed through the floor ducts will be
slightly warmer than the air sent to the windshield defroster ducts. If
the temperature is about 6ÉC (43ÉF) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging.

²(Defrost) ± Distributes outside air through the windshield
defroster ducts. It can be used to clear ice or fog from the windshield.
If the temperature is about 6ÉC (43ÉF) or higher, the air conditioner
will automatically dehumidify the air to reduce fogging.
Operating tips
²In humid weather conditions, place the climate control system in
Defrost mode before 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.
²
To 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 the 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.
²Do not put objects under the front seat which may interfere with the
airflow to the rear seats (if equipped).
²Remove any snow, ice or leaves from the air intake area (at the
bottom of the windshield and underneath the hood).
²Do not place objects over the defroster outlets. These objects can
block airflow and reduce visibility 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 the position that distributes air through the Panel and Floor.
2. Set the temperature control to full heat.
3. Set the fan speed to full fan.
4. Direct the outer panel vents towards the side windows.
5. 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.
ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC)
SYSTEM (IF EQUIPPED)
The EATC system will maintain a selected temperature and automatically
control airflow. You can override automatic operation with any of the
override controls or the fan speed control.

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. The outside temperature
function will continue to operate
until the ignition is turned 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. Fan speed
remains automatic unless the fan speed control is pressed or the steering
wheel fan speed control (if equipped) is pressed.
When in AUTO and weather conditions require heat, air will be sent to
the floor. However, if the engine is not warm enough to provide heat, the
fan will be at a low speed and the air will be directed to the windshield.
In approximately 3
1¤2minutes or less, the fan speed will start to increase
and the airflow location will change to the floor area.
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.

the temperature control.
For continuous maximum cooling, push the temperature control until
16ÉC (60ÉF) is shown in the display window. The EATC will continue
maximum cooling (disregarding the displayed temperature) until a
warmer temperature is selected by pressing the temperature control.
For continuous maximum heating, push the temperature control until
32ÉC (90ÉF) is shown in the display window. The EATC will continue
maximum heating (disregarding the displayed temperature) until a
cooler temperature is selected by pressing the temperature control.

REAR WINDOW DEFROSTER
The rear defroster control is located
on the instrument panel.
Press the rear defroster control to
clear the rear window of thin ice
and fog.
²A small LED will illuminate when
the rear defroster is activated.
The ignition must be in the ON position to operate the rear window
defroster.
The defroster turns off automatically after 10 minutes or when the
ignition is turned to the OFF position. To manually turn off the defroster
before 10 minutes have passed, push the control again.
Activating the rear window defroster will also activate the heated mirrors
(if equipped). For more information refer toHeated outside mirrorsin
theDriver controls chapter.
CABIN AIR FILTER (IF EQUIPPED)
Your vehicle may be equipped with a cabin air filter. This particulate air
filtration system is designed to reduce the concentration of airborne
particles such as dust, spores and pollen in the air being supplied to the
interior of the vehicle. The particulate filtration system gives the
following benefits to customers:
²Improves the customer's driving comfort by reducing particle
concentration
²Improves the interior compartment cleanliness
²Protects the climate control components from particle deposits
The filter is located just in front of the windshield under the cowl grille
on the passenger side of the vehicle.
For more information, or to replace the filter, contact your Ford, Lincoln
or Mercury Dealer.
