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 the
vehicle.
.Use of non-GM approved hood
deflectors may adversely affect
the performance of the system.
.Keep the area around the base
of the instrument panel console
and air path under the seats
clear of objects to help circulate
the air inside of the vehicle more
effectively.
Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter reduces dust, pollen, and other
airborne irritants from outside air
that is pulled into the vehicle.
Reductions in airflow, which may
occur more often in dusty areas,
indicate that the filter may need to
be replaced. SeeMaintenance
Schedule on page 11-2.
{Caution
Driving without a passenger
compartment air filter in place can
cause water and small particles,
like paper and leaves, to be
pulled into your climate control
system which may cause damage
to it. Make sure you always
replace the old filter with a
new one. The passenger compartment air
filter is on the passenger side of the
engine compartment near the
coolant surge tank. See
Engine
Compartment Overview on
page 10-7.
To check or replace the air filter:
1. Release the retainer clips from the passenger compartment air
filter cover. The PVC hoses may
need to be held out of the way
briefly to access the air filter
cover.
2. Remove the cover.
