inlets at the base of the windshield that may
block the ?ow of air into your vehicle.
? Use of non-GM approved hood de?ectors 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 air?ow seems low when the fan is at the
highest setting, the passenger compartment air ?lter
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 ?lter, which is part of a three piece ?lter
system. The ?lter removes certain particles from the air,
including pollen and dust particles. Reductions in
air?ow, which may occur more quickly in dusty areas,
indicate that the ?lter needs to be replaced early.
The particle ?lter is located inside of the air control
module. The air control module is located behind
an access panel near the accelerator pedal.
