sorry for the non BMW question, but i need some help
My wife drives the 2004 Subaru Legacy L 35th Anniversary Edition (as if that matters

) and the A/C-ventilation smells musty, so i need to replace the cabin filter in it.
Only problem is, i dont know where it is.
I know we have a few subaru drivers here, so hopefully someone knows! i dont have any service manual like a bentley for it, nor do i want to get one yet, and i cant find too much on the internet (might help if i spent more than than 5 mins looking tho probaby

)
