AdriansAvalanche09

I have a 2009 Avalanche, both rear windows wont operate with the front or individual switches. I replaced the main driver side switch with no success, I checked all the wires and fuse box on driver side. Any ideas?

I have an 09 LTZ Avalanche, both rear windows will not operate. I cleaned the contacts, checked all fuses, child lock, replaced the main control and still no resolution. I hear no noise, only the front windows will roll up and down, all the lights on the control work. What else can I check? any ideas would be greatly appreciated.
