What difference does it make if they tear the dash apart? It will all go back together lol. They had my terrain overnight to get my Bluetooth fixed and I know there was crazy amounts of wires hanging all over the place lol
After over 4 months my Onstar issues have been corrected with a module replacement. Luckily it's just above the accelerator pedal and only the knee plate of dash was removed. Too many time dashes, door panels and the like end up with scratches, broken connecters or rattles so I'm always reluctant to have them messed with. Dealer said they had never replaced one so must be fairly rare.
