Pontiac 2005 Grand Prix - Manual (Page 139)

Outlet Adjustment
Rotate and turn the air outlets, located in the middle
and at each outboard side of the instrument panel,
to adjust the direction of the airflow.
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 path under the front seats clear of objects
to help circulate the air inside of the 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” following, for more
information on this filter.
Passenger Compartment Air Filter
The passenger compartment air filter is located near the
passenger’s side windshield wiper arm, underneath
the inlet grille.
The filter traps most of the pollen from entering the
climate control system. Similar to the engine’s air filter,
it may need to be changed periodically to insure
system performance. See Scheduled Maintenance on
page 6-4 for more information.
To change the passenger compartment air filter, do the
following:
1. Turn the ignition to ACC and the windshield
wipers on.
2. Turn the ignition to off when the windshield wipers
are in the upright position.
3. Raise the hood.
4. Disconnect the windshield washer pump hose from
the fender rail and the air inlet grille.
5. Remove the hood weather-strip from the
passenger’s side of the vehicle, peeling it back
halfway.
