air conditioning Mercury Grand Marquis 2000 Owner's Manuals

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.
CLIMATE CONTROL SYSTEM
Manual heating and air conditioning system (if equipped)
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 FLR. However, the air conditioning will only function if the outside
temperature is about 10ÉC (50ÉF) 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 NORM 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.
²NORM A/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.
²FLR-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.
²MIX-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 windshield defroster ducts. If the
temperature is about 10ÉC (50ÉF) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging.
²DEF
-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 reduce fogging.
Operating tips
²In humid weather, selectbefore driving. This will reduce fogging
on your windshield. After a few minutes, select any desired position.

Fan speed ()
When AUTOMATIC is pressed, fan
speed is adjusted automatically for
existing conditions. You can override
fan speed at any time. To control
fan speed manually, use the
thumbwheel to cancel automatic fan
speed operation. Rotate the
thumbwheel up for higher fan speed
or down for lower fan speed.
The display will show
to
indicate manual fan operation.
To return to automatic fan operation, press AUTOMATIC.
Manual override controls
The override controls are located at
the bottom of the EATC and allow
you to determine where airflow is
directed. To return to full automatic
control, press AUTOMATIC.
The air conditioning compressor can operate in all modes except FLOOR
and VENT. It will also operate only when required when AUTOMATIC
has been selected. However, the air conditioning will only function if the
outside temperature is about 10ÉC (50ÉF) 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.
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. The temperature
display will remain the same and air will be cooled based on the
selected temperature. To exit, press AUTOMATIC or any other
override controls. MAX A/C is noisier than NORM A/C but more

Important ventilating information
If the engine is idling while the vehicle is stopped in an open area for
long periods of time, open the windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped) to bring in fresh air.
Improve vehicle ventilation by
keeping all air inlet vents clear of
snow, leaves and other debris.

How fail-safe cooling works
²Standard cluster
²Optional cluster
If the engine begins to overheat:
²the engine coolant temperature gauge will move to the H (hot) area
(if your vehicle is equipped with analog gauges).
²the engine coolant temperature gauge will illuminate all eight bars and
a tone will sound every five seconds for one minute (if your vehicle is
equipped with digital gauges).
²the
symbol will illuminate.
²theCheck Engineindicator light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
²the engine power will be limited.
²the air conditioning system will be disabled.
