Condensation inside double glazing

[PMB]

All,
I have a problem with condensation within the window.
Unfortunately the window (Dometic) does not have the normal plastic grommets to remove and solve the issue. Rather than getting my drill out and pop a hole on the inside side of the window, does anyone have a suggestion?

Leave well alone. It’s something to do with the stuff they’re made of. It’s not like home glass. We were worried about it in the rear panels on our previous PVC. It only happened on the rear doors. One more than the other. The ones without bungs.
Something to do with temp changes. The manufacturer of our PVC even sent us a leaflet from the window manufacturer . It came and went. We finally stopped worrying!

I noticed it one day in our new van when we were away as well.

As above it comes and goes but doesn't stay. Keep the drill in tge tool box.
