1996 BUICK REGAL air conditioning

Section 3 Comfort Controls and Audio Systems
In this section you’ll find out how to operate the comfort
control and audio systems offered with your Buick. Be
sure to read about the particular systems supplied with
your vehicle.
Comfort Controls
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.
Air Conditioning with Electronic Controls
Fan Lever
The bottom lever selects the force of air you want.
Temperature Lever
The upper lever changes the temperature of the air
coming through the system. Slide the lever toward
WARM for warmer air. Slide the lever toward COOL
for cooler air. This lever controls the temperature for the
whole vehicle unless
DUAL is pressed and the indicator
is lit. When
DUAL is pressed, this lever controls the
temperature for the driver.

The lever on the passenger's
door sets the temperature
for the front seat passenger.
Press the
DUAL button on the system face so the light on
it is lit. Slide the lever on the door toward
W to raise the
temperature. Slide it toward
C to lower the temperature.
To allow the driver to set
the temperature, push the DUAL
button again. The
panel has several settings to control the direction
of
airflow. The indicator light on the button will glow
when
the button is pressed.
OFF: The setting turns the system (including the
fan) off.
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 defrost and side window vents.
FRONT This setting directs most of the air
through the defroster and side window vents. Some
of
the air goes to the floor ducts. The air conditioning
compressor will run automatically
in this setting unless
the outside temperature is below
40°F (4.5"C).

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 (4.5"C).
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
(4.5 " C).
BI-LEV: This setting brings in the 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 (4.5"C).
Air Conditioning
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time the
compressor has to
run, which should help fuel economy.
For quick cool-down on very hot days, use
MAX with
the temperature lever all the way to COOL.
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 lever all the way to COOL. 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 with the temperature knob in the
middle. 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.

Heating
On cold days, use HTR with the temperature lever all
the way to
WARM. 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 System
Adjust the direction of airflow by moving the
louvered 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.
