Dash cluster isn't working.

The cluster has been repaired and tested. I know this is an electrical problem, but I'm not sure where the problem may be. I was trying to see if anyone else had these problems

Yes I see them//fix them quite often at the shop!... Until it has been tested as suggested... I don't know how you will ever know exactly where the actual problem area is.... Good luck with it!!

I had Chevrolet run the cluster test and nothing was found. They said it was probably a short in a wiring harness, so I took it to my shop and had one of my guys test all the harnesses... Nothing. That's why I'm lead to believe that there and internal problem behind the dash. If I plug the pro scan into my comp outlet, the cluster works. The scanner is completing the circuit. The harness to the cluster has all been tested and is good to go. I'm not sure if the cluster harness ties into another or what the deal is
