I bought a 99 Accord from my girlfriend and it has had all the required factory service at the correct interval. I recently had it in to Honda and they changed the cabin filter. Since then I noticed I am getting a lot of dirt and dust in the car on the dash and console which never happened before. Is there a diffferent problem to look for before I try taking the glove box out to check the cabin filter? I think they did something wrong changing the filter.

I have to park under a tree and crap in the air system is not a new problem with my old Mazda. But it never happened before with the Honda.
