Just wanted to say Thank you to everyone for posting helpful tips on this site. After 3 years I have finally fixed the drivers flooded footwell problem, I have spent many hours trying to fix this and now thanks to this site I found the answer , and to perhaps help someone else the flooded footwell had caused the joints on the wiring loom to rust and this had caused the central locking to stop working. Fingers crossed all now seems to be OK. So to everyone who takes the time and trouble to answer posts and to share information with others THANK YOU VERY MUCH
