1. Check your cowl cover under which the cabin air filter is sealed. If it is not installed properly, water from rain / washing will leak into the footwell area near the blower fan and mold will start to grow.
2. While at it, change your cabin air filter as well. It has activated carbon in it and absorbs bad smell. If it hasn't been changed, it is probably saturated.
