Outlet Adjustment; Passenger Compartment Air Filter - Buick 2005 Park Avenue Owner's Manual

Outlet Adjustment

Use the thumbwheel located in the middle of the front
outlets to change the direction of the airflow and to open
and close the outlets.
Use the thumbwheel located between the rear
passenger outlets to open and close the outlets. Adjust
the direction of the airflow from side to side with the
levers in the center of each rear outlet.
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 on page 3-30.

Passenger Compartment Air Filter

Passenger compartment air, both outside air and
recirculated air, is routed through a passenger
compartment filter, which is part of a three piece filter
system. The filter removes certain particles from the air,
including pollen and dust particles. Reductions in
airflow, which may occur more quickly in dusty areas,
indicate that the filter needs to be replaced early.
The particle filter is located inside of the air control
module. The air control module is located behind
an access panel near the accelerator pedal.
