2001 FORD F250 air condition

What you should do if the Service Engine Soon light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourService Engine Soonlight to
illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the gas cap. After three driving cycles
without these or any other temporary malfunctions present, theService
Engine Soonlight should turn off. (A driving cycle consists of a cold
engine startup followed by mixed city/highway driving.) No additional
vehicle service is required.
If theService Engine Soonlight remains on, have your vehicle serviced
at the first available opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Air bag readiness
Momentarily illuminates when the
ignition is turned ON. If the light
fails to illuminate, continues to flash
or remains on, have the system
serviced immediately.

4. Press and hold both trip
computer controls. After
approximately four seconds, the trip
computer will enter zone setting
mode. Zone setting mode is
indicated when the display lights the
“ZONE” indicator.
5. Release both controls.
Subsequent pressing of either
control will increment the zone.
Press the control repeatedly until
the correct zone setting for your geographic location is displayed on the
trip computer.
6. To exit the zone setting mode and save the displayed zone in memory,
release both controls for greater than five seconds.
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 eight 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.

Temperature control
Controls the temperature of the
airflow inside the vehicle. On
heater-only systems, the air cannot
be cooled below the outside
temperature.
Mode selector control
Controls the direction of the airflow
to the inside of the vehicle.
•
(Panel) -Distributes outside air through the instrument panel
registers.
•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.
•
(Floor) -Allows for maximum heating. Distributes outside air
through the floor ducts.
•
(Floor and defrost) -Distributes outside air through the floor
ducts and the windshield defroster ducts.
•
(Defrost) -Distributes outside air through the windshield
defroster ducts. It can be used to clear ice or fog from the windshield.
Operating tips
•In humid weather conditions, place the climate control system in
DEF before driving. This will reduce fogging on your windshield. Once
the windshield has been cleared, operate the climate control system as
desired.
•To reduce humidity buildup inside the vehicle in cold weather
conditions, don’t drive with the climate control system in the OFF
position.
•Under normal weather 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.

•Under snowy or dirty weather conditions, your vehicle’s climate
control system should be left in the OFF position when the vehicle is
parked. This allows the climate control system to be free from
contamination of outside pollutants.
•Do not put objects under the front seat that will interfere with the
airflow to the rear seats (if equipped).
•Remove any snow, ice or leaves
from the air intake area at the
base of the windshield.
•Do not place objects over the defroster outlets. These objects may
block airflow and reduce visibility through the windshield. Avoid
placing small objects on top of the instrument panel. These objects
may fall down into the defroster outlets and block airflow, in addition
to damaging the climate control system.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or a sudden stop.

The air conditioning compressor can operate in all modes except
and. However, the air conditioning will only function if the outside
temperature is about 6°C (43°F) 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.
•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.
•

•If your vehicle has been parked with the windows closed during warm
weather conditions, the air conditioner will perform more efficiently in
cooling the vehicle if driven for two or three minutes with the
windows open. This will force most of the hot, stale air out of the
vehicle. Once the vehicle has been “aired out”, operate the climate
control system as desired.
•Do not put objects under the front seat that will interfere with the
airflow to the rear seats (if equipped).
•Remove any snow, ice or leaves
from the air intake area at the
base of the windshield.
•Do not place objects over the defroster outlets. These objects can
block airflow and reduce your ability to see through your windshield.
Avoid placing small objects on top of the instrument panel. These
objects may fall down into the defroster outlets and block airflow, in
addition to damaging the climate control system.
Do not place objects on top of the instrument panel, as these
objects may become projectiles in a collision or sudden stop.
To aid in side window defogging/demisting in cold weather conditions:
1. Select PANEL & FLOOR
2. Set the temperature control to full heat
3. Set the fan speed to HI
4. Direct the outer panel vents towards to side windows
To increase airflow to the outer panel vents, close the central panel
vents.

The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system warning (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to theAir bag readiness
section in theInstrumentationchapter. Routine maintenance of the air
bag is not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light will either
flash or stay lit.
•The readiness light will not
illuminate immediately after
ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Disposal of air bags and air bag equipped vehicles
(including pretensioners)
For disposal of air bags or air bag equipped vehicles, see your local
dealership or qualified technician. Air bags MUST BE disposed of by
qualified personnel.
