Was cleaning up today and noticed about a tablespoon full of foam in powder form on the highest part of the carpet below the glove box and outboard of the condensate drain. I looked around under there with a light and mirror and didnt see where any seals were coming apart.

I'm thinking it may be the fresh air door seal since it's hot and humid here. I vacuumed a couple weeks ago and nothing was there.

Any ideas on how to tell what had disintegrated under there?

On a side note, I recently had the passenger air bag recall taken care of. Not sure what that entailed.
