Climate Control Systems
The heating, cooling, and ventilation of the vehicle can be controlled with
this system.
A. Temperature Control
B. Fan Control
C. Air Delivery Mode Control
D. Air Conditioning
E. Recirculation
F. Rear Window Defogger9
(Off): Turn the fan control to this
position to turn the fan off. Air still
enters the vehicle and increases
with vehicle speed depending on
the mode and temperature settings.
Turn on the recirculation mode to
stop this airflow.
Temperature Control: Turn
clockwise or counterclockwise
to increase or decrease the
temperature of the air in the vehicle.

8-2 Climate Controls
9(Fan Control): Turn clockwise or
counterclockwise to increase or
decrease the fan speed.
Air Delivery Mode Control: Turn
clockwise or counterclockwise to
change the direction of the airflow in
the vehicle. The airflow can be set
between modes.
To change the current mode, select
one of the following:
H (Vent): Air is directed to the
instrument panel outlets.
\(Bi-Level): Air is directed to the
instrument panel outlets, and the
remaining air to the floor outlets
and the defroster and side window
outlets. Cooler air is directed to the
upper outlets and warmer air to the
floor outlets. [
(Floor): Air is directed to the
floor outlets, side window outlets,
and defroster. Recirculation is not
available in this mode.
/ (Floor/Defog): This clears the
windows of fog and moisture. Air is
directed to the windshield, side
window, and floor outlets. The
system runs the air conditioning
unless the outside temperature is
near freezing or below. Recirculation
is not available in this mode.
0 (Defrost): This clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield and side window
outlets. The system runs the air
conditioning system unless the
outside temperature is near or
below freezing. Recirculation is
not available in this mode.
Do not drive the vehicle until all the
windows are clear. #
(Air Conditioning): Press to
turn the air conditioning system
on or off. An indicator light comes
on when the air conditioning is
turned on. This system cools and
dehumidifies the air entering the
vehicle.
The air conditioning will not
function if the fan is turned off.
If air conditioning is selected with
fan off, the indicator light flashes
three times and then turns off.
A slight change in engine
performance may occur when the
air conditioning compressor shuts
off and turns on again. This is
normal. The system is designed
to make adjustments to help with
fuel economy while still maintaining
the selected temperature.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.

Climate Controls 8-3
@(Recirculation):Press to turn
the recirculation mode on or off.
An indicator light comes on when
the recirculation is on. This mode
recirculates and helps to quickly
cool the air inside the vehicle. It can
be used to prevent outside air and
odors from entering the vehicle.
Recirculation is available in the
bi-level and vent modes. This mode
cannot be selected while in the floor,
floor/defog or defrost modes. If you
try to select the recirculation mode,
the indicator flashes three times
indicating it is not available in that
mode. When the recirculation mode
is turned on, the air conditioning
turns on automatically. When it is hot enough outside, the
recirculation mode may turn on
automatically to help improve
cooling performance. The indicator
light will be lit to show this mode is
active. If the recirculation button is
pressed while in this mode, the light
flashes three times and stays on to
indicate that recirculation may not
be shut off.
Rear Window Defogger
The rear window defogger uses
a warming grid to remove fog or
frost from the rear window when the
key is in the ignition and turned to
ON/RUN.
=
(Rear Defogger): Press to turn
the rear window defogger on or off.
After the button is first pressed the
rear window defogger stays on for
about 15 minutes. If turned on
again, the defogger only runs for
about seven and one-half minutes.
Notice: Do not use anything
sharp on the inside of the rear
window. If you do, you could cut
or damage the warming grid, and
the repairs would not be covered
by the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal or anything
similar to the defogger grid.

Air Vents
Use the air outlets located in the
center and on the side of the
instrument panel to direct the
airflow.
Move the louvers up or down to
change the direction of the airflow.
Use the thumbwheel under the
outlets to change the direction of
the airflow from left to right.Operation Tips.Use the recirculation mode for
maximum air conditioning
performance.
.Clear away any ice, snow or
leaves from the air inlets at the
base of the windshield that may
block the flow of air into the
vehicle.
.Use of non-HUMMER approved
hood deflectors may adversely
affect the performance of the
system.
.Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
