Cotswold over cab window

Hi guys,
I might be in the wrong place for this but here goes anyway.
I have a 2012 Cotswold and have noticed that there are a few small cracks starting at the top of the forward roof light. There is a little condensation but no obvious water leakage. Is there a way to repair this or is it a replacement job.

If I need a replacement where is the best place to look and how much am I looking at 🧐

Thanks for any help or suggestions

All I can say, and it's not cheery news, is that failure of these windows has become a problem in caravans where people are having to replace them.

I had to replace my remis 900 x 600 remis skylight i found the best supplier was autosleeper parts ..

There have been cases of these windows coming away from the body when driving , I would get this checked as soon as possible as this could be the first sign’s of this happening
