I have asked this on two other forums and no one can give me an answer. How is the door panel removed on an 08 DTS?

 

I have a neighbour who is a retired trim tech from one of the largest Cadillac dealers in our area. Just yesterday he was showing me on my car how this is done. He said the panel is one of the nicest designs he ever worked on. it is secured by clips and the top of the panel hooks onto the door frame at the base of the window. He said once you get the clips free you pivot the panel out and up and it pops off.
