The $JB $horting out i$ major.
To help prevent that from happening in the event the car leaks water in that area, tape one end of a piece of polyethylene sheet to the fender's interior wall so it's just a little higher than the top of the passenger side plastic kick panel(SJB is behind this panel). Then drape the other end of it over the top of the kick panel, and tape that end to the kick panel's outer surface. Any water that leaks in that area should now run down the polyethylene onto the carpet. You can also place a few folded paper towels under the lower edge of the kick panel to absorb any dripping water. Make sure to use tape that will stick to the fender in both hot and cold weather, and check it every few weeks or so to make sure it's still in place. Also, check the paper towels after every heavy rain and replace them if they're wet.
Works for me!!!
