Does anyone know where the cab filter is located, and how to go about changing it???? A mechanic at the dealership said to remove the covering under the dash on the passenger side and that it would be right there, but after doing that I don't see anything that would be removable containing a air filter.

I wish my 02 Hoe didn't have an in cabin filter. It didn't get changed for 3 years. It got all moldy and smelled rotten when the A/C was on. The dealer charged me $56 to change it. Next time, it comes out and stays out. $36 for a filter that you have to pull the glove box out to change every 6000 miles? NOPE!
