I'm doing a headliner in an 06 land rover Autobiography edition and I have all the handles and light panels down. I took out the little screws around the headliner on the front and the sides of the sunroof opening but the rear of the sunroof has the slider in the way so how do I get to those so that I can drop it and slide it out? Also the vehicle dash lights are on with the ignition on but I can't work anything like the seats or sunroof. What do I need to do?
