inlets at the base of the windshield that may block
the flow of air into the 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 the vehicle
more effectively.

If the airflow seems low when the fan is at the
highest setting, the passenger compartment air
filter, if equipped, may need to replaced. For more

If fogging reoccurs while in vent or bi-level modes
with mild temperature throughout the vehicle, turn

Passenger Compartment Air Filter
The vehicle has a passenger compartment particulate
air filter. It is located in the engine compartment, below
the air inlet grille on the passenger side.
The filter traps most of the pollen from air entering
the climate control system. It needs to be changed
periodically to ensure system performance.
For information on how often to change the passenger
compartment air filter, see Scheduled Maintenance
on
page 7‑3
.
To change the passenger compartment air filter:
1. Turn off the ignition when the windshield wipers
are in the up position.
2. Raise the vehicle hood.
3. Pull back the hood weatherstrip from the
passengers side of the vehicle halfway to center.
