Not his car but will work for asking the question.
Water is collecting on the bottom of the inside of both rear passenger doors right behind the b pillar. All door and window seals appear to be intact but if left in the rain enough it will spill over from sill into the footwell. While it is garage kept at his house it is not at school so hence his question. He showed me today after work when he opened the door and a “small” amount of water landed on the parking lot.
Feel free to ask questions or for pictures of his car and said pool of water if we can recreate it easily.
