Finally decided to change the cabin filters for the ventilation system after 40,000 miles. Got the filters and started to go to work. Turns out it is more difficult than I thought. Do I have to remove duct? How do you change the filters? Thanks

You have to remove the acess panel near the gas pedal. Remove the filter in 3 pieces and install the new filter in pieces. It is a real time comsuming job to do!

Thanks. Sounds more simple than it turned out. Got it done after 45 minutes. Boy, were those filters dirty.
