I have a 2008 Tahoe with OEM Bose nav/backup camera, rear entertainment system, etc. There is no power to the rear AC control / radio controls on the center console. I've Ohm tested all fuses and there appears to be no open circuits. If I turn on the AC Aux up front, it controls the rear AC but nothing is displayed on the screen. Anybody know where to start with troubleshooting this thing? Thanks!

 

If you have checked all fuses and verified power to the panel, I would suspect the panel is the problem...
might try pulling the panel and making sure everything is plugged in good...

 

I checked GM parts Direct and I THINK the part you may be looking for is 15881861 but you will need to check that yourself with your options

 

Thanks for the help
