How to remove a door panel from a Cadillac DeVille?

To remove a door panel from a Cadillac DeVille, first, ensure the window is fully closed and disconnect the battery for safety. Carefully pry off any trim covers and remove screws securing the panel, usually located near the handle and bottom edge. Use a flat tool to gently detach the panel from the door frame by lifting it upward once all fasteners are removed. Finally, disconnect any electrical connectors for Windows or locks before fully removing the panel.
