1999 FORD CROWN VICTORIA air conditioning

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 ten 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 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 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 prevent fogging.

It can be used to clear ice or fog from the windshield. If the

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 will 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 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

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
economical and will cool the inside of the vehicle faster. Airflow is
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. The temperature
display will remain the same and air will be cooled based on the
selected temperature. It is quieter than MAX A/C but not as
economical. Fan speed will remain automatic. Airflow is from the
instrument panel registers.
²VENT-Distributes outside air through the instrument panel registers.
However, the air cannot be cooled below the outside temperature
because the air conditioning does not operate in this mode.
²FLOOR-Allows for maximum heating by distributing outside air
through the floor ducts. However, the air cannot be cooled below the
outside temperature because the air conditioning does not operate in
this mode.
²FLR²DEF-Distributes outside air through the windshield defroster

Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is present in exhaust
fumes. Take precautions to avoid its dangerous effects.
If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
Have the exhaust and body ventilation systems checked whenever:
²the vehicle is raised for service.
²the sound of the exhaust system changes.
²the vehicle has been damaged in a collision.
Engine exhaust, some of its constituents, and certain vehicle
components contain or emit chemicals known to the State of
California to cause cancer, and birth defects or other reproductive
harm.
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.
Starting
116

When this occurs the vehicle will still operate, however:
²the engine power will be limited.
²the air conditioning system will be disabled.
Continued operation will increase the engine temperature:
²the
symbol will begin to flash.
²if your vehicle is equipped with digital gauges, the gauge bars will
flash and a tone will sound every five seconds for one minute.
²the engine will completely shut down, causing steering and braking
effort to increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
Never remove the coolant reservoir cap while the engine is
running or hot.
5. Re-start the engine and take your vehicle to a service facility.
Driving the vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to a
service facility as soon as possible.
