First gen Toyota Tundra & Sequoia trucks develop a water leak on the passenger side that results in a wet floor, the water comes from cowl screw grommet gaskets that fail with age. OEM parts are available, and they are fairly easy to replace. It's a good idea to replace all of them as well as any push pins and holders while you are at it. I put a little silicone sealer on the grommets to help make the seal last. I have performed this repair on three vehicles this month.
