2005 Nissan Altima 4 cyl Two Wheel Drive Automatic 102000 miles
We had a couple days of some steady rain, no monsoons or anything, and I notice a puddle forming on the floor of the rear seat, behind the passenger seat. I brought it to the dealership, where they ran a water seal test, and they couldn't tell me anything but that the car is fine. The water was only on the floor, not coming through the door or window. I did notice that under the carpet was wet all the way up to the front passenger seat. Any advise would be helpful. Anything I could check out myself, without involving another garage?
