Long story short i i jumb started started to Cadillac as i turnd the key and made a clicking noise as the battery was dead then the Theftlock came up on the navigation screen and the traction control and airbag light is on and trunk will not open the carruns fine so I want to order a new Bcm and two of them are coming up body control module that's underneath the glovebox and a rear Bcm I don't know where that one is located but I'm sure I need to one that controls the traction control light airbag light and the truck thanks joe
