I have a 2013 and just changed the cabin filter 2 days ago. It is exactly the same as the 2011 in the youtube video posted earlier in this thread. EXACTLY. Just hope they put the clips in right at the factory or you'll learn a whole new realm of curse words while trying to remove them!!! The filter is behind a black panel in the blower motor housing and it is not as painfully obvious as you might think. That panel door integrates seamlessly into the rest of the black plastic behind the glovebox so as to be almost invisible. Once box is off, look to the middle left. It tilts slightly/is at an angle with the right corner lower than the left. The clips are on the bottom. Again, these don't just fall off either, it takes some oomph.
My guess is the 2014 is in the same location, they just made it easier to drop the glovebox.
