thanks to both you guys. ah-kay, you've described my situation perfectly. Some water drips from the lock button, and when the lid is fully raised, the water pours in. I never could figure out where it was coming from, so it makes sense that it is being retained in the lid after a rainstorm. Any idea where to get a properly sized rubber fitting? I was thinking of hitting a home depot and getting several sizes, since i will be eyeballing it.
