In this section you’ll find out how to operate the comfort
control and audio systems offered with your vehicle. Be
sure to read about the particular systems supplied with
your vehicle. Fan Knob
The knob on the left side of the heating system control
panel controls the fan speed. The knob has four speed
positions. To increase airflow, move the knob toward
HI. To decrease airflow, move it toward LO. To turn the
fan off, move the knob to
OFF. Comfort Controls
Standard Climate Control System Temperature Knob
The middle knob on the control panel lets you select
the relative temperature of the air flowing into the
passenger area of your vehicle. This knob will allow
you
to adjust the relative air temperature independently of
the function knob setting. Move the knob clockwise
toward the red area for warmer air. Move the knob
counterclockwise toward the blue area for cooler air.

The middle knob on the control pane-1 lets you select
the relative temperature of the air flowing into the
passenger area of your vehicle. This knob will allow you
to adj.ust the relative air temperature independently of
the function knob setting, Move the knob clockwise
toward the red area for warmer air. Move the knob

Mode Knob
The right knob on the control panel allows you to
choose the direction of air delivery. The control knob
can be placed in any position between any two mode
settings to blend the flow of air.

Rear Air Conditioning and Heating Systems
(Suburban)
’
If your vehicle has either or both of these systems, you
can increase and decrease the airflow at the rear vents.
Depending on the system
you have and the setting
selected,
you can send cooled or heated air to the rear of
the vehicle.
Rear Air Conditioning (Without Rear Heater)
If your vehicle has rear air conditioning (without rear
heater), the controls are located above the front and
second seats. The front and rear overhead controls let
you increase and decrease the airflow at the rear vents.
To operate the rear air conditioning system, the front air
conditioning system must be on. With the front air
conditioning system off, the rear system controls can be
used to circulate air in the rear of the vehicle.
3-3

Downloaded from www.Manualslib.com manuals search engine To regulate the airflow location, adjust the center knob
on the control panel. Turn the knob clockwise for floor
vent airflow or counterclockwise for headliner vent
airflow. Generally, the upper vents are used for air
conditioning and the floor vents for heating. The control
knob can
be set to any blend setting.
To adjust the aifflow speed, turn the fan control knob
on the left side of the control panel to the desired
blower setting.
To activate the rear control, move the fan knob on the
front control
to REAR CNTL.
Air Conditioning
On hot days, open the windows long enough to let hot
air inside 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.
The recirculation button, between the fan and temperature
knobs, allows the air inside your vehicle to be
recirculated. This setting helps to maximize your air
conditioner’s performance and your vehicle’s fuel
economy. This setting also cools the air the fastest and
can be used to keep unwanted odors and/or dust from
entering the vehicle. When using the air conditioner, turn
off recirculation after the vehicle reaches a comfortable
interior temperature. When the right knob on the control
panel is between HEATER and DEFROST, the
recirculation feature will not function.
The A/C button, between the temperature and mode
knobs, allows the air coming into your vehicle to be
cooled. This setting is useful for normal cooling on hot
days. When
you use A/C with the recirculation button
pushed in, turn off recirculation as soon as the vehicle
reaches a comfortable interior temperature.
The
rear control works just like the front control. It will
allow second seat passengers to adjust the controls as
they desire.

Downloaded from www.Manualslib.com manuals search engine With the A/C on, move the temperature knob to MAX
for maximum cooling. This setting also puts the system
in the recirculation mode and helps to maximize your air
conditioner’s performance and your vehicle’s fuel
economy. This setting also cools the air the fastest. After
the vehicle’s interior reaches a comfortable temperature,
move the temperature knob clockwise to place the air
conditioning system in the normal mode.
The heater works best if you keep your windows closed
while using it. On cold days, use the HEATER or
VENT/HEAT setting with the temperature knob in the
red area.
If you use the engine coolant heater before starting your
engine (in cold weather (20°F (-8OC) or lower), your
heating system will produce warmer air faster, to heat
the passenger compartment in cold weather.
The use of an engine coolant heater also reduces the
time it takes for the engine to reach normal operating
temperature, and shortens the time it takes the heater to
reach full output. For more information, see “Engine
Coolant Heater” in the Index. Ventilation System
For mild outside temperature when little heating or
cooling is needed, use VENT to direct outside air
through your vehicle. Air will flow through the
instrument panel outlets.
Your vehicle’s ventilation system supplies outside
air to the inside
of your vehicle when it is moving.
With the side windows closed, air will flow into the
front air inlet grilles, through the vehicle, and out the
air exhaust valves.
Outside air will also enter the vehicle when the heater or
the air conditioning fan is running, unless you have the
recirculation button pushed in. For more information
on
the recirculation button, see “Air Conditioning” earlier
in this section.
