Thanks for the video, but there's a little problem. On the QX30, the lock on the side of the door is the same, but there is no bolt cover in the handle. There is no detachable element. And I don't want to pull by force. See picture.
Select with a color on the photo which element it is about.
I was pulling out the door panel. You unscrew the screws under the armrest (it has no full cover, only the little plugs. You have to look under the armrest) and pull the panel towards you to release it from the latches. remember about the side bolt that you have to pull back.
When you release the latches, lift the panel up until it comes out of the upper fastening of the gutter.
I didn't remove the tweeter cover because I couldn't. I tried to remove the panel without touching the tweeter.
