I have had the problem with my 90 LX, 93 LX, and 93 EX. Most were solved with new gaskets between the light housings and body. Be careful removing the light housings on the trunk lid, there is one place you have to reach in to pinch a barbed fastener, otherwise you'll break it when pulling the light housing off. The 90 also had a broken seal where the colored part of the housing met the black back part of the housing at the top, water filled the lense and drained into the trunk. A thin bead of clear silicone along the top of the housing solved that. Also check the vent on the lower left side of the trunk behind the lining, I think I had to replace that gasket on one of them (have to take the rear bumper cover off). Make sure all holes have plugs in 'em.
