How to adjust tension on a front vent window.

Does anyone know how to adjust the tension on a front vent window? It's the only aircon I have in my EH and as it is now quite slack it won't stay open to direct air onto me. Thanks in advance.

there is a 5/16 nut on the bottom of the quarter window frame
inside the door with a spring that gives the tension
you will need to tighten the nut probably half a turn
to make the window stiffer
spray plenty of wd 40 on it

it will probably be seized if it hasnt been moved in 50 rs

The nut on the bottom of the quarter window that tensions the spring is crimped at the factory so it cannot turn. Turning the nut will only break the bolt off the window frame.
The only way to fix it is to pull the whole quarter window assembly out and crack the nut with a nut with a nut splitter, the put a new nut on and tension it. Then crimp the new nut.

Old is good.

Thanks Guys. Judging by your comment "Old is good" the spray painters already broke the nut. Hopefully there is something left to fix.

If the spray painters took the quarter window out to paint the door they shouldn't have had to touch the nut. The whole quarter window assembly with the seal comes out in one piece with the front window channel.
Did they put an new quarter window seal in the door? If they did they would have had to undo the nut and might have broken it if they didn't see that it was crimped.
If you haven't got a new seal on the quarter window an old worn seal with a gap under the glass will be loose.
