I understand. You might look at United Radio in Syracuse, NY. They are one of the repair facilities authorized by GM. A lot of dealers send their stuff to them. I have never sent them anything myself.
The other one is Instrument Sales and Service in Kent, WA. I have also used Advanced Auto Electronics out east. They were able to repair a digital instrument cluster that United Radio could not for lack of parts.
