Water can also come under the screen seal and travel back to the holes for the heated screen cables. I've got my screen off at the moment to replace the seal.....not a job I'd recommend!
People seem to accept leaks as part of the Morgan experience. I don't!
I can accept the slight drop from the hood but in my view leaks from under the dash and heater just should not happen.....they've been building the cars for decades! Morgan needs to bloody well get it sorted!!
