XC60 Door Window Sticking
 

(Sorry.. thought I'd posted this earlier - but can find it - so here I go again)

My XC60 passenger window mechanism is struggling, groaning... It goes down OK but only comes up 50% and then grumbles and sticks.

Tried both driver and passenger controls and it's identical. Seems mechanical, rather than electrical. If I push window gently outwards it works better and so I sense it is out of line but can't see how as all else seems fine.

I've managed to close it by coaxing and have taped up button.
Don't want to overburden motor and fear cost after seeing electrical problem posts on this...

Anyone else had this or, even better, sorted it?
