take off the rubber thing that goes the width of the scuttle. undo the 2 screws and wiggle the tray like youve never wiggled before and itll come out exposing the pollen filter. see if its wet or not, it might have dried out by now. give the whole area a good clean just in case. this would be a good chance to change the pollen filter. as for it seeming to come up through the carpets, if it coming in where mine did it will seem to do this. i had a puddle in my rear foot well!
