All of the driver information display quit. The digital speedometer, the driver information like MPG and miles to fuel etc. The fuel gage and analogue speedometer still work. Also the digital heat and cool info is gone. The Temp setting for left and right temp is gone.

Is this the Dash information module or the body control module. I feel like it is just the power for the lcd display, because everything seems to function. If I turn up the temp it gets warmer, the A/C works or the heat as needed.

Any Ideas? I can not check codes as that is the display that is not working.

This can be a serial data class 2 problem so have a pro scan it with his scanner. Check the ign 1 fuse in the rear fuse block as that can be blown. You can also try pressing the display mode button and seeif one of the cluster or info center comes on. Or try the info reset button see if that makes one of them work. It may be just a bad cluster that is causing the problem if not a class 2 problem.
