dash board wiring schematic

[Bdubb]

Would anyone happen to have or know where i could locate a copy of the dash wiring schematic for a 2006 yukon xl Denali? I'm trying to track down a bad ground in the illumination circuit.

let me know what you find I'm having some issues with mine, I swapped the radio for one with all good bulbs and it only lights up the power and svc.

The best schematic I could find was in the Chilton report guide. I was in the process of replacing my crept, so my seats and everything were already out. There were a couple of melted illumination wires under the passenger front seat inside the factory loom. I isolated those wires and taped them. Now my window and heated seat buttons work again. I pulled the dash apart to meter the illumination wires for the heater controls and swc buttons. They all have power at the switches but bulbs don't light unless I send them a ground with my probe. Seems as the trace in the bcm that sends the adjustable ground for dimming is burned. I'm gonna be swapping in a spare bcm to check it.

This is my first Tahoe and I'm not sure where the bcm is.
