Window Mechanism repair instructions

[Tim06]

I'm in need of a bit of help! The window mechanism on my multispace has broken plastic clips which secure the glass. I have ordered and received new clips, (the rectangular ones that fit to the cables in the guides), but can't work out how to remove the old ones and then fit the replacements. I obviously bought from the wrong source, as I have now seen others, (more expensive), that say that they will supply a video instruction link after purchase, but the ones I have don't have any instructions. Does anyone have instructions or a video link that I can beg?
Cheers,
Tim

There are tutorials on YouTube, you might have to search in French. Try "leve-vitre Berlingo".
