what are the sources of water leak to back seat of camry 2000 le
Check your spare tire storage compartment and the compartments where the jack is stored. What happens most of the time is the rubber dry rots around the tail lights and side parking lights. When it rains, it will come through lights and fill the trunk with water. Also make sure the trunk lid water drains are not full of leaves and dirt. Other than that, I wouldn't know how water could get under the seat. The only other thing would be a bad window seal.
