Default Mystery plugs rear driver's side

I have the 2011 Express AWD cargo van for work. Just bought it about a month ago. While looking at the wiring harness at the rear, I noticed 3 factory looking plugs with nothing plugged into them. Does anybody know what they are used for?

rear heat/ac? Maybe the rear door speaker on the one side. You can find a wiring diagram online....

Thanks for the link. Apparently they are there for auxiliary HVAC and rear window defogger circuits.
