Where is the cabin air filter located on a 2005 Buick Lacrosse?

On many American cars, it's located under the hood, on the passenger side of the car. Frequently, you remove the clips securing the windshield wiper cowl on the passenger side. There might be a cover inside that needs to be removed, in order to get to the filter.

Park the wipers in the up position and remove the right side air inlet grill.
The cabin filter is mounted below that grill.
