Just a guess but do your heating,vents operate properly? They are all controlled via vacuum

As asked, is it sucking air (vacuum line) or is it a line that needs a vacuum to control the other end. A clue is where does the other end connect?

Is this a 2021+ model with the new V8 or a 2020- model with the V10?

FWIW, all Axis/Vegas models, not just the 25.5 will have the same engine compartment configuration.

If it goes to a control and is not a source and you can not find an un-used source to hook it to, how about installing a t fitting in another vacuum line? You could always cap the t if you find the correct source line. Another option would be to get a cheap smoke machine on Amazon and smoke out the missing connection.

Post #6 you indicated it was a vacuum line, by that I understood "pulling vacuum".

Can you tell us or post a better picture of what the 'blue' end is connected onto?

Sorry, you're 4 days too late.
I just put that side of the RV and the doghouse back together.
There's no way for me to see it now.

I suggest you plug the line and try every a.c. setting and all switches.
