238 Climate Controls
Sensors
The solar sensor, located in
the defrost grille in the middle
of the instrument panel,
monitors the solar heat. Do
not cover the solar sensor or
the system will not work
properly.
There is also an exterior
temperature sensor behind
the front grille. This sensor
reads the outside air
temperature and helps
maintain the temperature
inside the vehicle. Any coveron the front of the vehicle
could cause a false reading in
the displayed temperature.
The climate control system
uses the information from
these sensors to maintain
comfort settings by adjusting
the outlet temperature, fan
speed, and air delivery mode.
The system may also supply
cooler air to the side of the
vehicle facing the sun. The
recirculation mode will also be
used as needed to maintain
cool outlet temperatures.
Afterblow Feature
If equipped, under certain
conditions, the fan may stay
on or may turn on and off
several times after you turn
off and lock the vehicle. This is
normal.
Air Vents
Adjustable air vents are in the
center and on the sides of the
instrument panel, and on the
rear of the center console
storage.
Move the slider knobs to
change the direction of or to
close off the airflow.
Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at
the base of the windshield
that could block the flow of
air into the vehicle.
.Clear snow off the hood to
improve visibility and help
decrease moisture drawn
into the vehicle.
.Keep the path under the
front seats clear of objects
to help circulate the air
inside of the vehicle more
effectively.
.Use of non-GM approved
hood deflectors can
adversely affect the
performance of the system.

Climate Controls 239
Check with your dealer
before adding equipment to
the outside of the vehicle.
.Do not attach any devices to
the air vent slats. This
restricts airflow and may
cause damage to the air
vents.
Maintenance
Passenger
Compartment Air
Filter
The filter reduces dust, pollen,
and other airborne irritants
from outside air that is pulled
into the vehicle. The filter
should be replaced as part of
routine scheduled
maintenance. See
Maintenance Schedule0471.
See your dealer regarding
replacement of the filter.
Service
All vehicles have a label
underhood that identifies the
refrigerant used in the vehicle.
The refrigerant system should
only be serviced by trained
and certified technicians. The
air conditioning evaporator
should never be repaired or
replaced by one from a
salvage vehicle. It should only
be replaced by a new
evaporator to ensure proper
and safe operation.
During service, all refrigerants
should be reclaimed with
proper equipment. Venting
refrigerants directly to the
atmosphere is harmful to the
environment and may also
create unsafe conditions
based on inhalation,
combustion, frostbite, or other
health-based concerns.
The air conditioning system
requires periodic maintenance.
See Maintenance Schedule
0 471.
