How hard is it to get at? I'm pretty sure there is mildew growing somewhere in my AC system I'm hoping its the filter so it'd be easy to fix the problem, I was just wondering if it would be easy to check and if so replace without having to deal with the dealer.

 

Mildew grows in and around the core due to pericipitation. But it does not hurt to change the filter.

The filter is located behind your glovebox. Search for directions on this forum. That is what I did and it was easy. You cant do it without directions though.
