Foggy windows

[Pkowski]

Looks like my sealed leaking on the pilot side double pane on my 08 XL
2 questions
1 is this fixable without buying a new window
2 if so can it be done by an dyi'er?

Thanks in advance.

The inert gas has leaked out, thus the fogging. It is repairable, check Google.

A hair dryer won't fix it.

There isn't any gas between the panes of glass. I have done tons of research recently on this as I have three windows that are foggy. The seal is leaking allowing moist air in and fogging up. The windows are sealed with a product that contains silica (sp?) that dries out the air that is between the glass. Once the seal is broke, it can't dry it out anymore and the window becomes foggy. Google foggy RV window and you will get tons of hits including YouTube videos. It can be a DIY depending on you. I am going to try it.
