1998 BUICK REGAL air conditioning

Comfort Controls
Manual Single Zone Climate Control
[OD I COMFORT CONTROL
With this system, you can control the heating, cooling
and ventilation in your vehicle. The system works best if
you keep your windows closed while using it.
Fan Knob
The left knob selects the amount of air you want. To turn
the fan off, turn the knob to OFF.
If the airflow seems very low when the fan knob is
turned to the highest setting, regardless
of the mode
setting, your passenger compartment
air filter may need
to be replaced. See “Maintenance Schedule” the Index.
~~~
Temperature Knob
The center knob changes the temperature of the air
coming through the system. Turn this knob toward red
(to the right) for warmer air. Turn it toward blue (to the
left) for cooler air.
Mode Knob
The right knob has several settings to control the
direction of airflow:
MAX: This setting recirculates much of the air inside
your vehicle and sends it through the instrument panel
outlets. The air conditioning compressor will run
automatically in
this setting unless the outside
temperature is below
40°F (4°C). (Even when the
compressor is running, you can control the temperature.)
NORM: This setting brings in outside air and sends it
through the instrument panel outlets. The air conditioning compressor will run automatically in this
setting unless the outside temperature is below
40°F
(4°C). (Even when the compressor is running, you can
control the temperature.)
BI-LEV: This setting brings in outside air and directs it
two ways. Half of the air is directed through the
instrument panel outlets. Most of the remaining air is
directed through the floor ducts and a little to the defrost

and side window vents. The air conditioning compressor
will run automatically in this setting unless the outside
temperature is below
40°F (4°C).
VENT This setting brings in outside air and directs it
through the instrument panel outlets.
HTR: This setting sends most of the air through the
ducts near the floor. The rest comes out of the defroster
and side window vents.
BLEND: This setting allows half of the air to go to the
floor ducts and half to the defroster and side window
vents. The air conditioning compressor will run
automatically in this setting unless the outside
temperature is below
40°F (4°C).
FRONT This setting directs most of the air
through the defroster and side window vents. Some of
the air also goes to the floor ducts. The air conditioning
compressor will run automatically in this setting unless
the outside temperature is below
40°F (4" C).
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down.
For a quick cool-down
on very hot days, use MAX with
the temperature knob all the way in the blue area. If this
setting
is used for long periods of time, the air in your
vehicle may become too dry.
For normal cooling on hot days, use
NORM with the
temperature knob in the blue area. The system will bring
in outside air and cool it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use
BI-LEV and set the temperature knob to a
comfortable setting. The system will bring in outside air
and direct it to your upper body, while sending slightly
warmed air to your lower body. You may notice this
temperature difference more at some times than others.

all the way in the red area. The system will bring
in outside air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it’s
cold outside
(0°F (-18°C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater’’
in the Index.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, use
VENT to direct outside air through
your vehicle. Your vehicle also has the flow-through
ventilation system described later
in this section.
Defogging and Defrosting
Your system has two settings for clearing the front and side
windows. To defrost the windows quickly, use
FRONT with
the temperature knob all the way in the red area.
For maximum defroster performance, set both driver and passenger temperature controls to the warmest setting.
To warm passengers while keeping the windows clear,
use
BLEND.

Dual Automatic ComforTemp Climate Control (If Equipped)
With this system, you set a temperature. You can then
either let the system automatically control aifflow
direction and force to maintain the temperature, or you
can manually adjust it. The system works best
if you
keep your windows closed while
using it.
Automatic Control
For the most efficient operation, you should set the
system temperature and press AUTO. The system will
select the best fan speed and airflow settings to keep you
comfortable. The air conditioning compressor will run if
the outside temperature
is above 40°F (4°C). You may
notice a delay of two to three minutes before the fan
comes on at start up in cool weather.
Driver’s Temperature Control
The TEMP switch sets the temperature for the entire
system when the light on the
DUAL button isn’t lit. If
the light is lit, this control sets the temperature for the
driver only. Press the up arrow to raise the temperature
and press the down arrow to lower the temperature. The
display will show your selection for a few seconds, then
the outside temperatwe will be displayed.
If you push
the AUTO button, the system will control the fan speed
and airflow.

9 FRONT This setting brings in outside air and
directs most of the air through the defrost vent. Some
of
the air also goes to the floor ducts and the side window
defogger outlets. The indicator on the button will light
and WINDSHIELD will be lit in the display.
The air
conditioning compressor will run automatically in
this setting unless the outside temperature is below
40°F (4°C).
VENT: This pushbutton turns the air conditioning
compressor on and
off. The indicator lights when the
compressor is turned off. Recirculation is not permitted
when the compressor
is off. The system will try to
control the temperature automatically, but without
the compressor.
Vent is not permitted in FRONT defrost mode. If the
vent button is pushed while in FRONT defrost mode,
the indicator will light for one second and then turn off.
RECIRC: This setting recirculates much of the air
inside your vehicle. This setting is not permitted in
FRONT defrost mode and is only permitted in
WINDSHIELD/FLOOR mode if the compressor is
turned
on. The indicator light will be lit when
recirculation is engaged, but will light for
one second
and then turn off if selected when not permitted.

Heating Ventilation System
On cold days, use HTR with the temperature knobs all
the way in the red area. The system will bring in outside
air, heat it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it
to help your system provide wm air faster when it’s
cold outside
(0°F (-18°C) or lower). An engine coolant
heater wms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” in the Index.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows.
To defrost the windows quickly, press the
FRONT button; set the temperature to 90 OF (32”C),
select high fan speed and turn the DUAL button off. To
warm passengers while keeping the windows clear, push
the AIR
FLOW button until WINDSHIELDFLOOR
appears in the display. Select fan speed for comfort and
windshield clearing performance. Adjust the direction
of airflow by moving
the vents.
Your vehicle’s flow-through ventilation system supplies
outside air into the vehicle when it
is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.
If the airflow seems very low when the fan knob is
turned
to the highest setting regardless of the mode
setting, your passenger compartment air filter may
need
to be replaced. See “Maintenance Schedule’’
in the Index.
