Have you checked the fuse yet? If not, the fuse you are needing to look at is located in the fuse panel located under the hood inside the engine compartment. It will be the fuse marked "RR HVAC"
Below is a picture of the location of the fuse panel and a picture of the layout of the fuses. Maybe it was just me but it took me awhile to find that fuse so I want to give you a lttile head start as to its location in the panel. It's a little to the right of the center towards the top. I hope this helps and good luck.

check the wires where they connect and plug in on both corners of rear window...sometimes they break off and lose contact ....they can be reglued on using a special glue that will conduct electrical current through it...can be found at most auto parts srores...good luck....Lee

There is a blower motor control processor for the back blower - it takes input from the front control and the rear control and decides the fan speed. That processor could be faulty, or the blower motor, or a 30amp fuse in the engine compartment.
In the front system you have a controller and blend doors that direct air thru the heater core and evaporator. You would need to check the operation of those blend doors.
