the air inlets at the base of the
windshield that can block the flow of air
into the vehicle.

Clear snow off the hood to improve
visibility and help decrease moisture
drawn into the vehicle.
.
Use of non-GM approved hood deflectors
can adversely affect the performance of
the system.
.
Keep the path under all seats clear of
objects to help circulate the air inside the
vehicle more effectively.

bi-level modes with mild temperature
throughout the vehicle, turn on the air
conditioner to reduce windshield fogging.
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
.
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
