Rear driver's side door still won't open inside or out
Here's where it gets weird: the control panel seems to not work. The reclining rear seat is in the forward position and won't go back.
I checked all the fuses in under the passenger rear seat, and they checked out fine. I checked power, and they all have power, including and especially the suspect fuse, F72.
I've searched other threads on this, and mercedes' unreliable door actuator seems the likely culprit.
I have found these links:

I haven't tried the WD40 and pushing method, I will try that in due time.
In the meantime if someone has another suggestion, it's starting to get desperate.
that will change in the future as parts supplies dry up.




The panel not working makes me think there might be damage from whatever broke in there that hit those wires, but there is no way to know without opening up the panel.
Basically exactly what this guy did:
I used the passenger side door to find where the latch mechanism sits (relative to the outside). Went with a spray can of kroil and inserted the straw approximately there. Gave a spray. Door instantly opened.
Like instantly, not "oh with some fussing". No. Instantly. If you have a stuck door, first try this. I've now gone ahead and lubed all the door latch mechanisms with some lithium grease.
