I have a2002 Carens that has developed a leak into the cabin on the passenger side and pools in the footwell. The drivers side is dry. I have inspected under the wheel arches and sealed all the areas / joints where water could enter the cabin. My thoughts are it may be entering via a window seal or thegulley by the windscreen wipers, however to prove this means removing the dash (no small task). Has anyone else experienced the same problem if so how did you fix the leak?
