As I have taken off all 4 door cards over the past week for various different fixes, the back ones have total of 9 clips, 3 both sides, and 3 on the bottom. Overall the process is basically the same as for the front panels.
The 3 on the bottom are attached to the door card plastic part which is stronger than the rest. Thus they can withstand more pulling.
The 3 on both sides are attached with plastic 'extensions' that are glued to the door card. Most of mine were pulled off since the yellow clips are stronger than the glue that holds those extensions.
As I still have one of my rear door covers off, this is what it looks like from the back side. Note that only 3 of the 5 slots on the bottom are in use (both ends and the middle):
Thus be prepared to glue back those extensions to the sides (note the L shape pressed marks on the door card where the exact location of those extensions should go). Also be prepared that many of the yellow clips will partially break. May still be usable later though.
The top part at the window edge slides in with up-down movement. So it is important that the card removal starts from the bottom where you pull straight towards you, the sides will follow, until all 9 clips are either off or broken off. And then lift the door card upwards to come out from the window edge.
When having to glue back any of those details don't use regular silicone or super glue as it won't hold over time (previous owner had done that). I used this T-Rex glue that I found in the hardware store. Super strong yet still a bit elastic.
