Took the vehicle to a mechanic and he was able to us his code reader. There were no codes present so it seems that I just can’t connect to Onstar using cellular service. I wondering if we can delete and then reinstall the programming on the Onstar module. Any ideas. Dealer keeps saying there’s nothing wrong.
