Had the same problem with the small struts on my van.
Here's the fix which is working well for me.
The issue is they use a small ball bearing held against the telescopic post which is held against the post by a spring. The ball bearing gets rusty and the whole thing seizes or becomes very difficult to move.
The spring despite its size places too much pressure on the ball bearing.
There's a small clip which holds the spring and ball bearing in place.
Lever it off and remove the spring and ball bearing.
Clip off with side cutters about one or two loops of the spring. The idea is to weaken the spring tension. If you clip too much off just stretch the spring so that it places just a small amount of tension in the ball bearing. Being small windows it doesn't need much.
Oil the whole show and put it back together.
Should be good to go then.
Cheers.
Andrew.
That's what I like about this forum is the willingness to help out a fellow traveler.

Thanks
@twscoot I will have a look on Saturday and hopefully fix them.
It makes sense with the rust on the ball bearing because we did 2 weeks camping on the beach.
I tried spraying silicon spray but your right the ball-bearing are too tight, in fact way too tight.
I did take the spring out so I could disconnect the struts so we could make it home and deal with them later under warranty. I will try your idea first thought and see how it works but I thinks your right evan though cutting the spring I think there will be more that enough force on the ball-bearing to hold the windows in place.:encouragement:
Cheers for that
@twscoot how do you find this mechanism holds up in a bit of wind!
So far all good. And we copped a bit of wind head on to the window a few weeks ago.
I figured if it was too loose I'd just add some more tension to the spring by stretching it a little. But haven't needed to.[/QUOTE]
O I wish it was Saturday so I can fix my windows too
@twscoot
These windows drove me crazy on how I was going to fix them the whole 1300 kms from Coral bay to Perth.:doh:
