Where is the cabin air filter on a 2004 mercury mountaineer?

The cabin air filter on a 2004 Mercury Mountaineer is located behind the glove compartment. To access it, you need to remove the glove compartment by unfastening the screws and detaching it from the dashboard. Once the glove compartment is out of the way, you can find the filter housing, which typically requires removing a cover to reach the filter itself.
