Inside your SXS look under the 12 volt outlet there behind the black plastic mess you can see the cabin filter. To remove it you need a plastic thin pry bar and the cover is held on by 5 clips. pry at the top seam there are three there and one on each side. Pull cover off and you be able to remove filter to clean or replace. Pictures attached.Anyone know how to change/clean the cabin filter in a northstar?
