2009 avalanche Rear Windows Failure

[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?

 Pinched wire in the drivers side door/door jam?

with a voltmeter, check continuity from the switch. 

 

I would also check fuses. both going out at the same time doesn't add up. Also find the ground for these and check that also. Might be just a bad ground.
