Outlet Adjustment Turn the air outlets, located in the middle and at each outboard side of the instrument panel, to adjust the direction of the airflow. Passenger Compartment Air Filter The passenger compartment air filter is located near the passenger's side windshield wiper arm, under 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 473 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. 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. 166
