In a 2005 Buick LaCrosse, the cabin air filter is located behind the glove compartment. To access it, you'll need to remove the glove compartment by unscrewing the screws and releasing the stops. Once the glove compartment is out of the way, you can find the cabin filter cover, which can be removed to replace the filter.
