Wiper Seal

Even if you do the wiper pivot seal kit from Schumacher, don't be surprised when you still have water on the floor. Many times the wiper pivots get blamed for all the water coming into the interior and more often than not the primary contributor turns out to be something else. The real fix can be as simple as dropping the fresh air boxes and removing a build up of pine needles from the plenum floor, but you might find yourself attempting to seam seal the plenum box or pulling the windshield because you can't get to the leaks caused by the factory sealing mastic falling out of the holes under the windshield locating tabs any other way.
