If a vehicle was ordered with non-operational inner handles, the rods were to be put in the trunk, most likely they have been removed long ago...but it's worth a good look.
The window buttons were done in a few ways - 1) the factory disconnect behind the lower b-pillar trim next to the driver if they were ordered that way or properly disconnected by an upfitter that knew what they were doing, 2) unplugging the buttons themselves in each back door, 3) cutting wires.
You'll find a grey connector here, that is how they were disconnected in ordered that way.
