A good suspect for this type of leak is the plastic water shields right behind the door trim panels. If someone removed one to service something in the door, they have to be resealed completely or rain water will drip onto them, then onto the sill plate and onto the floor. The clue is the leakage will change significantly when you park the vehicle in a different orientation, such as with a different side higher or lower.
