Long shot, I don't think anyone reads this forum on a Sunday.
The drivers window got stuck 3/4 shut a few months ago and didn't have time to repair it before so only just getting around to it now.
Typical with anything I don't understand I took it apart and as I undid the 2nd of the 2 screws holding the restrictor to the door it popped out. Then I played with it and it sprung apart into two pices. So now I'm stuck not knowing which way up the two pices fit together and to the door.
I think I will probably work it out but if someone comes on here who can explain it then that's going to save me a few minutes.
