Have you tried pouring water over the scutttle vent area to see what happens. When checking for leaks it is always best to start from the bottom of the car and work up. A few dustings of talcum powder or dry newspapers are always helpful when looking for clues.
Are you sure its rain water and not coolant from the heater matrix.
