Dealer quote 10k repair for wiring harness
Has anyone dealt with this? I have a 2019 Sierra at4 and the 5v circuit was malfunctioning. The shop called me and told me that GM recommends replacing the whole engine wiring harness bc of the power issue it’s giving them. They said it will be 10-11k. They also said that the circuit could be “overlayed” but gm won’t let them do that. Does anyone know what that means?
