Cabin verses Combination filter
Questions, for the D service, is there only one combination filter, the one I refer to under the hood? What is the part number and about how much does it cost.
Thanks

The dust filter is changed often but I've heard the charcoal filter is only changed at 90K miles ...

These days the dust filter is a combo filter (used to be like that for the 2-zone AC). In any case changing the charcoal filters is a minor task. If you have not used them a lot (an a 2003 car those are not always used, just when the button is pressed or when the car decides the filters are needed), I would not even change those.
