Mystery operation

[Bakertech]

For no apparent reason my Trunk lid opens while it is in Winter Storage. It even happens when vehicle is locked. It will repeatedly open then close.
Shorted wiring somewhere? It also sometimes opens when the drivers door is opened.
Any guidance would be appreciated,

Well after much thought and installing a new battery, after 2 trickle chargers failed, I finally just disconnected the new Battery for a couple weeks. After reconnecting, the trunk lid appeared to behave. I took it out of the garage with fingers crossed, and tried the Top. Every thing worked.
I did not have to re-index the windows.
I am not saying it is Fixed, I am saying it Works. Perhaps some spurious voltage spikes from failing/failed trickle chargers scrambled the BCM or Computer. This may work for other mysteries.
