Thanks.
I've been curious about how to remove the cargo doir interior panel. Any info that have would be appreciated (by me and others, I'm sure).
Removing the inner liftgate panel was a MAJOR pain. A lot more difficult than the rear header panel. There are at least a dozen of those red and black fasteners spread fairly evenly across the panel, and it was hard to find good places to grab and pull. And you have to pull really hard! I was convinced I was going to break something major. I thought I took a photo of the inside of the panel to show where all the clips are, but I guess I didn't. There were 2 or 4 fasteners near the top of the panel, just below the window; another 2 along each side; another 2 or 4 across the bottom; and another 4 or so spaced around the middle. All of them are oriented so you pull straight down (toward the ground) when the liftgate is raised.
There were also two silver fasteners several inches to either side of the latch area on the bottom edge of the door panel. These were pretty easy to pop out, by pulling horizontally (when the ligtgate is open) away from the bottom edge of the door. You should pop these out before pulling down on the panel to release all of the red/black fasteners.
Before removing the panel, you need to disconnect the open/close switch on the bottom edge of the door. There's a little rectangle cap you pop off that reveals a torx screw, that gives you access to the wire connector to the switch. I also popped off the little piece of molding that surrounds the latch in the center. I don't think it was necessary to remove this, but it made it a lot easier to look around inside and see where everything was.
I ended up breaking about 6 of the red/black fasteners. By searching images of hundreds of different panel fasteners, I was able to identify the part number (11547026) and buy some replacements on Amazon (

If you're going to remove the panel that surrounds the sides and top of the window, you should do that before removing the main lower panel. If not, then there's a part of the panel that surrounds the top and sides of the window that you need to release in order to completely remove the main lower panel. The bottom of the panel "legs" that run down the sides of the window wrap around the "horns" that come up from the top of the main panel. There are two little tabs on the top piece that sort of "pinch" and lock into the bottom piece. You want to spread these apart to release the tabs.
FYI, the panel that surrounds the window has 6-8 of the dreaded red/black fasteners. For each of those, you pull "in" (i.e., toward the window area) and not "away" (i.e., out from the plane of the door).
