Either that or the heater matrix is fucked and leaking water in through the footwell vents.
Actually water can get through the glue, I recently had my screen crack along the bottom at the back of the screen , when the guy who came to replace it he found several rust holes partly in the bulk head and cockpit, and reckoned it was the pressure from the rust expanding causing it to crack, my cars a good few years older than a P though.
But its still a possibility, and now way to look either short of removing the screen or dash, oh maybe a hose at low pressure from inside the engine bay area, not really the best option though what with the heater blower etc in there too.
