Yes, I did and it wasn't pleasant. I finally found that the car had a leak around the seal of the front windshield, and it was dripping down into the front passenger compartment. The floor was soggy when I found it and I'd been looking for the problem for a while. The carpet had mold and mildew under it on the padding and that was the smell. I had to take the carpet out, let it dry and shampoo it, replace the padding and wash the carpet. I let it all dry and then reinstalled the carpet. I had to seal the windshield too. It was a mess.
