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 your 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 information, see

Filter on page 3-26

Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment particulate air filter. It is located
underneath the hood just below the windshield wiper
arm on the passenger’s side of the vehicle, underneath
the air inlet grille.
The filter traps most of the pollen from air entering the
Climate Control System. Like your engine’s air
cleaner/filter, it may need to be changed periodically to
insure system performance. For information on how
often to change the passenger compartment air
filter, see
Scheduled Maintenance on page 6-5
