1998 FORD MUSTANG air conditioning

CLIMATE CONTROL SYSTEM
Manual heating and air conditioning system
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 reduce
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

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.
