Thanks, that was what I hoped for. However, where to apply lubrication is not trivial (see image):)

You will need to oil the hinges and the balljoint on the end of the motor pushrod shaft which from your photo appears to be covered with a cap. I don’t suppose those parts ever see any maintenance be prepared to put plenty of oil on the hinges (you may need to apply several times as the hinges are now tight) I find engine oil works best

As per above, I'd look to remove the plastic trim cover to really get some oil into the hinge and shaft end.

You are probably right.
This is what I've got, which one would be appropriate?

WD40 will clean it but not lubricate it for very long. You can get quite a few decent oils in spray cans with a tube. I use silicone grease and lubricant on my key locks and roof mechanism.
