Left a back left window open in the rain. I got the seat dry but the foam padding under the carpet floor is still quite moist. Been throwing desiccant packs on it and letting a fan blow on it 24/7 but it's still damp.

What are my options to fix this cheaply? Can I just cut up the carpet/foam and throw it out and let the back seat floor be bare? If it's not molded I could probably just leave it in the sun and attempt to gorilla tape it back in.
