The cabin air filter in the Chevy Lumina filters out allergens and toxins from exhaust fumes as air enters the vehicle and passes through the air vents. The vehicle takes air from the cowl and brings it inside the vehicle. For this reason, the cabin filter is located under the cowl inlet grill. According to the owner's manual, you should replace the cabin air filter in the Lumina every 15,000 miles.
Lift the hood and prop it open. Disconnect the windshield washer hose from the cowl of the Lumina by pulling on the hose.
Pry the snap rings loose that attach the air inlet grill to the cowl, using a screwdriver. Pull the inlet grill up.
Pull the cabin air filter tray out from under the inlet grill. Pull the old filter out of the tray and place a new filter in the tray. Reinsert the tray under the inlet grill.
Push the inlet grill down against the cowl and push the snap rings back into place.
Reattach the washer hose to the cowl.
