I have a 2005 Envoy XUV. The overhead console switches that operate the sunroof, mid and rear gate windows, and roof, no longer illuminate when the lights are on. I've tried replacing the switch cluster, but still not illuminating. I'm thinking there must be a short in the wiring harness. Anyone encounter this or know how to trouble shoot, a wiring diagram?

Best bet is to buy a factory service manual it will have all the wiring diagrams... that and you need a good volt meter.....
