Thought I'd be proactive the other day, and (once I got my hood open after the release handle broke off) I popped the cabin filter housing cover off to check it out & replace.
Much to my surprise, there was nothing but a big hole there!
So mine has no cabin filter at all anymore, apparently removed and not replaced for unknown reasons by the previous owner. I can't tell if the correct housing is there for a replacement filter. Is the framework plastic or metal? The video on page 1 looks like a plastic frame that the filter slides into... all I see is metal on the edges of my filter reservoir.
