I recently bought a used 1999 Camry and yesterday after a day of heavy rains I found the passenger side carpet soaking wet with a small puddle of water on the rubber section of the floor mat on the same side. The wet area was limited to the section closer to the door and near the footrest. The car had been sitting all day since I drove it to work and was out in the rain for several hours. It has a sun roof and I checked around the roof for leaks, but there weren't any. Also the underside of the dash didn't feel wet. Only part that felt wet was the underside edge of the car when I ran my hand along the bottom near just below the door hinge, but I am not sure if that was the rain water still draining away from under the hood.
