Chevrolet Roadtrek - Cabin Air filter

I don't think you have one.

We have a 2001/2002 (depending on what paperwork you look at) Roadtrek 200 Popular on a Chevy Chasis. How do we tell the van model? And where do we look for a cabin filter to change?

I don't think the Chevy Express uses one, but our Patfinder does, and is replaced every 15,000 miles.

I think Chevy dropped the CAF a few years back.

Most don't even know that they have a cabin air filter and never replace it. I just looked in the Chevy manual for my 2011 Roadtrek and I don't see any mention of it at all. If one went for Chevy maintenance service at a Chevy dealer they would replace the filter automatically when the time came.
