Rear climate controls/stereo don't work?

What is your question?

Right behind the center console is a stereo/climate control that has no power, also the turn knob by gearshift that controls the rear climate control dont work. I also took apart the rear stereo/controls and used a test light to see if i was getting any power to anything and when i hit one of the wires the rear air turned on but loud blowing noise on right rear side that alot of air was coming out, i think it sounds like the ductwork came loose and its not getting air to the rear vents, any suggestions would be greatly appreciated. With the different problems i dont know where to start.
