renault clio central locking problem

hi guys hope someone can help me out here with this problem i own a renault clio expression 52 reg, the problem i'm having is the central locking is going nuts locking and unlocking itself i had a problem of water in the footwells in the past but i've managed to stop that but now for some reason the locks go mad ive checked the fuse and thats ok does anyone have any idea what the most probable cause is.



thanks
