Ford Excursion :: 2001 XLT - Rear Window Vent Actuators And Wiring

I recently purchased a 2001 XLT, 5.4L RWD. It has the rear windows with actuators installed. The upper console has the vent switches to open and close them. They don't work. I removed the upper console and the vent switches have no wires running to them and no visible wire harnesses that have been cut or removed.

With the headliner removed, I chased the wires from the actuators (white with brown/yellow with brown on the right and white with blue/yellow with blue on the left). These four wires meet up over the right rear door and run in a bundle to the upper console where they seem to end in the plug for the Rear A/C controller. There is no indication that these harnesses have been altered. They appear to be taped like they came from the factory.

My questions are, were the opening rear window vents standard on the XLT or only on the Limited? If only on the limited, would they have installed actuators regardless of what model and just dead-end the wires into open plugs? There may be the chance that the upper console was aftermarket because there is a price tag sticker on it...
