15 Explorer rear passenger doors are possessed!

I'd inspect the master door switch on the driver door first since it is random and effects both rear doors. It could also be the wiring too.
Take a minute and make certain the child lock is in the correct position and move it back and forth several times leaving it in the "off" or "unlocked" position. It is on both rear door jams on the door side. They may have been discontinued but it might be good to check. My 06 has them.
