http://www.autopartsource.com/catalog/7704.pdf I found a link with directions on how to replace the cabin filter on a Lincoln Navigator. It states it should take approximately 15 minutes to do the job. Pages 49-50 of this pdf file give directions along with drawings on replacing the filter for models 1998-2005 of the Lincoln Navigator.

There is no cabin air filter on an 03 Navigator
there is not cabin filter in Lincoln town car.
In the 2008 Lincoln Navigator, the cabin air filter is located behind the glove compartment. To access it, you need to open the glove compartment, remove any contents, and then detach the stops or hinges to allow it to drop down fully. The filter housing is situated behind the compartment, typically requiring you to remove a cover to reach the filter itself.
