Hey,
I'm trying to remove the 'gearbox' that controls the quarter glass or the "No Draft Ventilator" as the manual calls it.
I've removed the two bolts and then it should just come out, or as said by the manual, but mine wont budge.
Has anyone got any experience with this? i can get the quarter glass to move maybe 1cm by hand but the knob and gearbox has never done anything.
Any suggestions welcome.

 

I have removed one and it was a PITA, can't actually remember the trick to it but this picture may help.
