I have a third row 17 Sorento that currently has a rodent infestation. I have three messy kids and am trying to clean all the crumbs out. How on earth do I reach the space where my third row seats fold down? When I fold them a little ways I can see in the crack behind the seat that there is a ton of garbage back there. I try shoving the vacuum house down there but it doesn't really fit. Can I remove a seat or the back wall of the little cargo space that holds my jack?
