I too have recently had the problem where the boot switch refuses to work, the boot unlatches when the break pedal is released, and the keyfob button works okay. At first I thought it must be the boot switch unit, not helped by the fact that the problem goes away a couple of days after the rain has stopped. Cleaned out the switch, no real sign of water ingress in it -- couple of days (and some more rain) later, problem reoccurred. Have read through all the info here, and eventually homed in on the black connector block, near side, behind lots of hard to remove trim -- nothing obviously wrong with it, no sign of dampness, but touching it caused the latch to start jumping madly. Fiddled around a bit, and the latch started working normally, rear button works, no activity on break light deactivation. Still not certain as to exactly where the problem lies -- it must be a short somewhere, there's a cable disappearing from the black connector into the reversing lights / rear fog light assembly -- this is very low down and must constantly be exposed to kick-up moisture from the road.There was significant water ingress around the center rear break light, but disconnecting this assembly made no difference. There was slight water ingress around the tail-light assembly, particularly on the near side, indicating that moisture may have made it down to the connector block, but there's no sign on the block itself. Will have to keep monitoring the situation -- will post back if any more determinative information.
