I am new to this forum so please excuse any procedural errors on my part. My 1987 Sentra Hatchback has a serious water problem both front and back. In the rear, the right tail light assemblies fill with water and so does the spare tire well. My 1st thoughts were that it was leaking around the hatchback gasket area so I applied some silicone. This has not solved the problem. Do I need to pull the tail lights out and reseal them? I don't see any sealant around them. In order to get to them, I will have to pull an interior panel that is held in place with one way plastic fasteners, with the same color as the interior. Can I get more from the dealer? The front passenger side leaks water also. Thanks for any help!
