Unless you have a little experience of upvc forget it as you could end up with a window falling on you with no experience. Many locksmiths wont touch them but not that bad if you know what your doing.
as they have lots moving parts it could be sticking many places and unless you have a source for the correct new part get in a pro.I did one last week and the parts were unobtainable so had to replace and adapt with a completely different mech which was tricky and more time consuming as you have to realign every keep from scratch.
Actually, I was able to fix the problem by dismantling it and cleaning all the parts. It was a tricky job - moderately challenging technically but it depends on how good you are at putting things back together as they were before you dismantled them.
The entire issue was caused by a build-up of grit mixed with grease clogging up the mechanism, which I bet is responsible for 90% of similar problems.
I removed all the metal parts and washed them with soapy water, and stuck them back together with some grease to lubricate the moving parts. It's now the best window in the house!
I think the [b]fear[/b] of what might go wrong is the biggest obstacle in this, if you are modeately mechanically-minded. On the other hand, there is no doubt that you could end up with a window you can't re-assemble and the window itself could be dangerous if not properly supported as the hinges are dismantled.
I've seen lots more questions than answers on this problem throughout various forums so I thought some people might be interested to know that it can be done, if I wouldn't necesarily recommend it.
Taking photos of the mechanism at every stage would be a wise precautionto help with re-assembly.

Fantastic! I had a sticking 3 Directional window that was making hell of a creaking noise when i turned the handle. Following your advice i managed to clear the creaking and stop the window 'falling' out of its tracking at the same time! You sir are a legend!
