You could try this: https://www.cadillacforums.com/foru.../996986-multiple-rear-hatch-issues-fixed.htmlAlright, got it open. When suggested to pull the panel, have to instruct to pull panel starting above the window. It's open, but the liftgate won't lock now. I looked at the fuse under backseat, passenger side, and 10A fuse listed for hatch is good. Any other electrical I should check?
