Rubber/plastic liners on both sides of trunk are easy to remove.... its one or two phillips screws (i think) and then you pull the rubber liner out...... Underneath you will find finger hole size rubber drain that can be poked clear to drain the water..... I threw both my rubber trunk liners in the trash, knowing I'd like to keep an eye on the drain plugs...... after finding about 4" of standing water on passenger side - and maybe 2" of water on drivers side hidden underneath the dopey rubber trunk well liners.
