2011 Silverado EXT cab rear window rolled down now it won't do anything. I ordered a new regulator and that does nothing. I swapped the switch with the other door to confirm switch is good. I pulled boot from rear door, wires all look good. I'm kinda at a loss here. Any suggestions. I am at the point if I can figure out a way to manually move my regulator to the up position I will just leave it and not use the rear door window. PLEASE HELP!!!

 

This is one more reason I don't want lots of electrical stuff, that I can do manually, like open the back-window. Mine just slides open, but I just have a two-door 98 K-1500.
