There is one other thing on the door hinge area.
The stay that holds the door (almost) in the part/full open position can wear. If you hear a "clack" or "knock" noise as it opens fully then it is wearing out. You start to feel that it is arguing as you first start to pull it closed.
There is a pin top to bottom that can wear the slot oval, then it blocks making it difficult to close the door at all.
If you start to hear the clack (drivers door gets most wear and goes first) then best to get it looked at as well. It does require some work and not just a new pin.
Also if the battery goes flat (never happens, ha ha) then the windows will often not auto dip to miss the seal as you open/close the door. There is a simple process involving the ignition in position 1 and using the window button to reset it. I say it is simple sadly I am even more simple and cannot for the life of me remember it.
I also find this useful for finding your way around some elements.
