after 10 years of faithful service, all of a sudden, the passenger floorboard is getting soaked with every rain, parked or running. I finally found that the big drain hole, right below the plastic tray in front of windshield, which is at about a 45 angle is made up of two layers of sheet metal, the top metal is flared downward, but water was running under flare and getting in between the two layers, and into floorboard, why it didn't leak before i don't know. this drain hole is access by pulling two screws and pulling back rear inner fender liner.
