Gavin posted a topic in Audio, Electronics, OnStar, MyLink, Intellilink & SiriusXMI have a 2013 GMC Sierra and there is absolutely no power at all. The battery is good and the dash lights won’t come on. It won’t click when you turn the key. You can’t even lock the doors. Lights won’t come on when you open the door. Like I said the battery is good and I even tried to jump it just to make sure, but nothing at all. Any help is appreciated.
