Had heavy rains today and the passenger side floor was wet and the water would also create a puddle in the back. I replaced the cowl a month ago because water was leaking inside on driver side floor and that solved it.
I gave it to my brother to drive for a week and he told me about the water just now, where could the water be coming from on passenger side? I confirmed with him that it is cold water so from the rain not engine. Thanks

Hi,

Do you have a sun roof? There are drains on both the left and right side. Here are directions for replacing the drain. I'm adding all of it to help locate and inspect.

Next, if he was using the defroster or AC, it could be a leak from the evaporator drain. Check under the dash to see if that is where is seems to come from.

Let me know.
