Just got back from a 45 min. trip in the pouring rain. The whole back floor by the tail gate is soaked. I sealed where the floor mat meets the rear lower rubber seal. Can water go up through the drain holes of the tail gate then leak down from the access panel? The tailgate is tight against the lower rubber seal. I had my son take the leaf blower the other day and blow around the tailgate and glass and only felt air at the lower corners of the rear glass. I am sick of this. It is also leaking up front by the dimmer switch dripping from some where only when I drive it in the rain. I have sealed everything I know .
