Outlet Adjustment
Rotate and turn the air
outlets, located in the
middle and at each
outboard side of the
instrument panel,
to adjust the direction
of the airflow.
See Instrument Panel Overview on page 3-2 for
additional information on location.
Operation Tips
• 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 your vehicle.
• Use of non-GM 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 your vehicle more
effectively.
• If the airflow seems low when the fan is at the
highest setting, the passenger compartment air filter
may need to be replaced. See “Passenger
Compartment Air Filter” following, for more
information on this filter.
Passenger Compartment Air Filter
The passenger compartment air filter is located
underneath the inlet grille, which is located under
the passenger side windshield wiper arm.
The filter traps most of the pollen from entering the
climate control system. Similar to the engine’s air filter,
it may need to be changed periodically to insure
system performance. See
Part A: Scheduled
Maintenance Services on page 6-4 for information
on scheduled changes for this filter.
