it seems they started with an underdash hvac system and built the car around it...you will have to get under the dash and remove all lower dash plastic until you see the blower...listen for it first,then start removing plastic.. the filter is between the fan and the heater core, on top of it(looks like a tiny radiator).
The filter is located behind the glovebox just unclip the filter to remove it

Remove the glove-box and door so that you can see it better and it will be easier to remove the tabs............ Once the glove-box and door have been removed the cabin air filter is located between the evaporator and the main control box. Remove the tabs, the cover and then remove the cabin air filter..............
