where is the a/c filter located

I believe your talking about the cabin filter. It is located behind the glove box. open your golve box, then push the two clips to drop the glove box down and access behind it, after that you will see the A/C / Polem Filter. Push the clips remove the old filter and then place the new one back in. The filter is directional to air flow so check old one when removed. Put glove box back in original position and thats that. Make sure you empty your golve box. Heres a link to a youtube video http://www.youtube.com/watch?v=w1An_NeDR_U
