Truck is a 2011 Ram 2500 SLT CC 4wd. The rear windows won't roll down from either door switch or the driver door switch. Sliding rear window will not open either. I tried replacing the drivers door main switch with no changes. I noticed when i press the rear window switches while the switches are illuminated, they lose their illumination (where the front switches continue to stay illuminated during use). Anyone have any ideas? This is really getting on my nerves, any help would be greatly appreciated!
