The floors are all wet but mostly on the passenger side rear. I opened the trunk and there is a full puddle of water along the body cavity on the passenger side in the trunk. I checked the trunk seals and they seem fine. The only thing that I can think of is the rain gutter drains into/arround the rear tail lights. I replaced them not to long ago. Do those have to be caulked to keep water from coming into the trunk? If not then I am baffled. Has anyone had the same experience and know how to fix this?
