1999 Mercury Sable air condition

²To turn autolamps on, rotate the control up. The
preselected time lapse is adjustable up to
approximately three minutes by continuing to
rotate the control upward.
²To turn autolamps off, rotate the control down
until it clicks.
REAR WINDOW DEFROSTER
Clears the rear window of thin ice and fog. To
operate:
1. Turn the ignition to the ON position.
2. Press and release
the control once to
turn on. The light will
be lit while the rear
window defroster is on.
3. Press and release the control again to turn off.
The defroster will automatically turn off after fifteen
minutes.

Fan speed control
Controls the volume of air circulated in the vehicle.
Temperature control knob
Controls the temperature of the airflow inside the
vehicle.
Mode selector control
Controls the direction
of the airflow to the
inside of the vehicle.
The air conditioning
compressor will operate in all modes except VENT
and
. However, the air conditioning will only
function if the outside temperature is about 10ÉC
(50ÉF) or above.
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.
Under normal 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.
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.
²VENT-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)-Allows for maximum heating by
distributing 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, 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. If the
temperature is about 10ÉC (50ÉF) or higher, the
air conditioner will automatically dehumidify the
air to prevent fogging.

²-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
10ÉC (50ÉF) or higher, the air conditioner will
automatically dehumidify the air to prevent fogging.
Operating tips
²In humid weather, selectbefore driving. This
will prevent your windshield from fogging. 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.
²Don't put objects under the front seat that will
interfere with the airflow to the back seats.
²Remove any snow,
ice or leaves from
the air intake area
(at the bottom of
the windshield under
the hood).
²If the air conditioner works well in MAX A/C, but
not in A/C, this may indicate that the cabin air
filter (if equipped) needs to be replaced.
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 your air conditioner as you
would normally.
²
When placing objects on top of your instrument
panel, be careful to not place them 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.

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 fresh
outside air or recirculated air is required. Fan speed
remains automatic unless the fan speed control 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 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.
Temperature selection
The display window
indicates the selected
temperature, function
(AUTO or one of the
override controls) and
manual control of fan
speed (
)if
automatic fan speed is not desired.
To control the
temperature, select any
temperature between
18ÉC (65ÉF) and 29ÉC
(85ÉF) by pressing the
temperature control.

mode to prevent undesirable odors from entering
the vehicle.
Displaying outside temperature
Press OUTSIDE TEMP
to display the outside
air temperature. It will
be displayed until
OUTSIDE TEMP is
pressed again or until
any other control is
pressed. When the
EATC system is off and OUTSIDE TEMP is pressed,
the outside temperature will only be displayed for
four seconds.
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, select F-DEFbefore
driving. This will prevent your windshield from
fogging. 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.
