How to Install a Buick Cabin Filterby Leonardo R. Grabkowski
Many Buick vehicles have cabin filters installed to improve the interior air flow quality. These filters are commonly called cabin air filters or A/C filters. The cabin filter in most Buicks is in the engine bay, close to the firewall and the windshield. Buick recommends that you change your cabin air filter every 20,000 miles.
Turn your ignition key to the "On" position, and turn the windshield wipers on. When the wipers are in the highest position, turn the key off. (This step is not required for the Buick Lucerne.)
Open the hood. Pull off the three tabs from the passenger's side cowl cover (closest to the windshield). Use a flat-head screwdriver or pry tool to pull them off.
Pull out the old cabin air filter and discard it. Insert the new cabin air filter. Replace the cowl cover, and press down on the tabs.

To change the cabin air filter on these vehicles, open the glove box and squeeze together the sides; let the glove box drop down. Then the filter will be easily accessible. Replace it in the same manner as above.
