get inside your trunk on a heavy rain and watch where it leaks. my taillight seal and trunk seals were both fine, i actually found out water was getting in from the rear door weather strip around where the door closes. its the plastic trim piece that clips to the holes on the car body just above the actual car door. so when you open the door, its the only strip thats on the car body and not the door. i put some rubber sealer on the clips and snapped it back on, no more leaks.
