1999 FORD F250 SUPER DUTY air conditioning

Compass calibration adjustment
Perform this adjustment in an open area free from steel structures and
high voltage lines.
For optimum calibration, turn off all electrical accessories (heater/air
conditioning, wipers, etc.) and make sure all vehicle doors are shut.
1. Locate the trip computer located in the overhead console.
2. Start the vehicle.
3. Press and hold both trip
computer controls. After
approximately 8 seconds, the trip
computer will enter CAL mode. CAL
mode is indicated when the display
lights the “CAL” indicator.
4. Release both controls. The display
will return to normal, except that
the CAL indicator will remain lit
until the compass is sucessfully
calibrated.
5. Slowly drive the vehicle in a circle (less than 5 km/h [3 mph]) until
the CAL indicator turns off. It may take up to five circles to complete
calibration.
6. The compass is now calibrated.

Instrumentation
21

Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or a sudden stop.
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
(Panel) and(Floor). However, the air conditioning will only
function if the outside temperature is about 10°C (50°F) 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 “breathe” through the outside air inlet
duct. In snowy or dirty conditions, leave the mode selector in the OFF
position.

Controls and features

•MAX 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.
•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.
•
(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.
•OFF-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.
•
(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.
•
(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.
•
(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 10°C (50°F) or higher, the air conditioner
will automatically dehumidify the air to reduce fogging.
•
(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 10°C (50°F) or higher, the air conditioner
will automatically dehumidify the air to reduce fogging.
Controls and features

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.

How fail-safe cooling works
If the engine begins to overheat:
•the engine coolant temperature
gauge will move to the red (hot)
area.
•the
symbol will illuminate.
•the
symbol will illuminate.
•theService Engine Soon
indicator 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:
•the engine power will be limited.
•the air conditioning system will be disabled.
Continued operation will increase the engine temperature and the 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.
