2011 F350 lights turn on spontaniously
 

I don't expect much help with this wierd problem.:confused:
My 2011 F350 Crew cab's interior lights have started to turn on spontaniously. I've also had the alarm sound with all doors locked and no one around...like last night at 4am!! Sometimes just the running/clearance lights will turn on.
I've had a problem, also, with the left rear door (ajar/open) indicator lighting up in the dash. It will stay on even if the door is opened and reclosed. The light may go out but frequently comes back on...............
Any help would be expected before I take it to Ford and have some dumb service writer tell me I need a new radiator cap.......and the problem goes on.
