|Once all of the screws are removed, the switch turned off, and the final screw removed, you must also remove the small aluminum cover to the right (from rear) of the electronics area.
This cover has a variety of different bolts and screws the plastic screws on the front look like standard Philips, but may not unscrew, and will need to be pried out. There are two bolts on the back, one is hidden by the carpeting. Finally the plastic push plugs will need to be pried out. Once this panel is out, the big cover should easily lift out.
Final step is to remove the negative wire from the 12V battery(caution when this is disconnected, the rear hatch can only be opened with a key)
