sounds like a water leak at the cowl will have to remove the wiper arms and the platic cowl panels and use body seam sealer to re-seal the seams on the body.verify where it leaks with a water hose and a friend to look when you are wetting the area.good luck!

usually water in passenger floor board is almost always the heater core. if you don't want to replace or can't yet. take the to hoses running it to it off and either block them off or run them to eachother using piece of pipe that'll fit into hoses and use the hose clamps to seal
