air conditioning BUICK PARK AVENUE 1996 Owners Manual

The FAN control is used to select the speed of the
blower fan and the force of air you want. There are four
speeds to choose from. Moving the lever between LOW
and
HIGH will decrease or increase the fan speed. The
fan will be off when the system is off.
This lever regulates the temperature
of the air coming
through the system. Move the TEMPERATURE lever to
change the temperature of the air coming through your
outlets. Move the lever between COOL and WARM to
lower or raise the temperature.
de Cc .-
The buttons on your system allow you to choose settings
to deliver
air through lower, middle or windshield outlets.
RECIRC: Press this button to limit the amount of air or
cool the air in your vehicle. To turn off RECIRC, press
the button again. If you select FRONT defrost or
BLEND while RECIRC is selected, the system will
automatically turn
off RECIRC to prevent fogging.
VENT This setting directs airflow through the middle
instrument panel outlets. The air conditioning
compressor
is not working when VENT is selected.
HTR: This button directs air out of the heater outlets.
Most
of the air will come from the floor outlets while
some of it will flow through the windshield and side
window outlets. The air conditioning compressor is not
working when
HTR is selected.
BLEND: When BLEND is selected the airflow will be
split between the windshield and the floor outlets. The
air conditioning compressor will be operating.
FRONT This setting directs most of the airflow toward
the windshield.
OFF: The ventilation system always allows fresh air to
flow through your Buick when the vehicle is moving.
The system will try
to keep the air at a previously
chosen temperature. When the system is
off, the blower
fan is also off.
MAX: This setting directs airflow through the middle
instrument panel outlets.
NORM: This setting cools the air entering your vehicle
and directs it through the middle instrument panel outlets.
BI-LEV: This setting directs warm air to the floor and
cooler air to the middle instrument panel outlets.

Manual Operation
You may also manually adjust the air delivery or
fan speed.
AIR FLOW: This button is used to change the direction
of the arflow. The airflow choices available are FLOOR,
FLOOR-MID,
MID and WINDSHIELD-FLOOR. If the
system is set for
AUTO, pressing the AIR FLOW button
will display the current airflow direction and the comfort
setting. Press the
AIR FLOW up or down button again to
change the direction of the airflow.
If the
AIR FLOW up button is selected while in the
FRONT defrost mode, the system will direct the air
toward the WINDSHIELD-FLOOR. If the AIR FLOW
down button is selected while in the FRONT defrost
mode, the system will direct the air toward the FLOOR,
and the FRONT defrost mode will cancel. Notice the
arrows in the display.
OFF: If the passenger comfort control is turned on, it
can be turned
off by pressing the OFF button once.
Pressing the
OFF button a second time will turn off the
main system. Turning off the main system causes the fan
to turn
off and the airflow to be directed to the FLOOR.
The system will still try to keep the interior of the
vehicle at the previous chosen comfort setting. The
outside temperature will show on the display when the
system is
OFF.
The ventilation system always allows fresh air to flow
through your Buick when the vehicle is moving even
with the system in the OFF mode.
VENT The VENT button allows outside air to flow
through your Buick without the air conditioning
compressor working. Selecting VENT and the
AUTO
button at the same time allows the system to control
automatically without the use of the air conditioning
compressor or the use of the RECIRC mode. To
turn off
the VENT selection, push the VENT button again.
RECIRC: When RECIRC is selected, the system will
limit the amount
of outside air entering your vehicle.
This
is helpful when you are trying to cool the interior
of the vehicle quickly or limit the amount of outside air
entering your vehicle for some other reason. RECIRC
and AUTO may be selected at the same time. The
system will remain in RECIRC for
12 minutes or
until the ignition is turned off, then the system will
return back to the previously selected mode. RECIRC
can be selected in all manual airflow modes except
FRONT defrost. RECIRC cannot be selected with
the VENT button.

FRONT This selection is used to defrost the
windshield by directing the airflow toward the windshield.
If
FRONT is selected while in the AUTO mode, the fan
speed and the air temperature from the front defroster will
vary. If a manual
fan speed setting is selected, the fan
speed will remain at that selection until another fan speed
selection is made or the AUTO mode
is selected. To turn
off FRONT, press the AUTO or AIR FLOW button.
FRONT defrost will work better if any ice or snow is
cleared from the hood and the air inlet area between the
base
of the windshield and the hood.
Air Condi,,.
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
If you have the electronic touch system, for quick
cool-down on very
hot days, use MAX with the
temperature and fan speed adjusted to COOL and
HIGH.
For normal cooling on hot days, use NORM and adjust the
temperature and fan speed for your comfort. If REClRC is
selected while
in the NORM air conditioning mode, the
system works like
MAX and recirculates the air. Use
BI-LEV to deliver warm air to the floor and cooler air to
the middle instrument panel outlets.
If you have the dual automatic comfortemp system and
on very hot days using the AUTO mode, the system will
automatically enter the RECIRC mode and the
temperature door will be positioned at the full cold
position for maximum cooling. If the system
is not in
the AUTO mode, RECIRC should be selected to provide
maximum cooling. You can choose the extreme comfort
setting of
60°F (16"C), but the system will not cool any
faster by choosing the extreme comfort setting.
When the air conditioner is on, you may sometimes notice
slight changes in your vehicle's engine speed and power.
This is normal because
the system is designed to cycle the
compressor on and
off to keep the desired temperature.
