I was just looking into what I need to do to replace the cabin air filter on my 2012 Routan SEL. I found a video how to do it on carcarekiosk .com, and it looks like it's supposed to be behind the glove box. I went and checked behind my glove box and found something very different. I was expecting a plastic panel, behind which the filter should be. Instead I found a metal cage, that looked empty, with no way to get into it, except maybe some screws that were not able to get to easily. Is this where it is supposed to be at, or is it somewhere else on this model?
