How to eliminate knocking and creaking in the cabin?

Question:

I have a problem with a creak in the cabin, above the head of the front passenger, next to the handle.
At first it creaked quietly, at first the fist hits helped, but now the creak has intensified, I don’t even know how to be, how to eliminate it, I don’t even know where to start, remove the casing, and where to start - I don’t know, maybe someone will tell you what’s wrong , or someone had, and how to remove the trim to get to this place. 

Answer:

I propose to remove the handle, ride, listen. If the sound remains, remove the sun visor, observe again. Then remove the trim on the right A-pillar.

You can get to the place by dismantling all of the above + lining of the middle pillar and the upper part of the doorway seal, and bending the ceiling. If there is a desire to remove the ceiling completely, there are also lanterns and behind it, like a couple of caps, there are other seals and linings that support it.
