As if the doors locking and unlocking whenever they feel like it wasn't enough - not to mention the time it started on it's own - now there's a very faint high pitched whine and a fast clicking noise coming from the DS kick panel when the door is open. It's barely audible but I think I tracked it down to the relay panel down there. The clicking at least. The whine seems to come from everywhere and nowhere. But when I touch the relays, I can feel the clicking. I think the black square device is the source. What is going on here?
