Nice one, someone else with that problem! Mine stops and starts working when it feels like it so i disconnected the plug behind the switches so at least if it doesnt work at all, it cant stick down on me when its raining(like it)! I did notice however if you mess about locking and unlocking the doors it occassionally starts working again. Think i'll try another switch cluster from a breaker. See if you can borrow one off anyone to try.
