Rear Lounge Windows - Need Education
We have a partially fogged window in the rear lounge on the driver's side.   I'd be grateful to anyone to who can explain how these windows are repaired.  Is the tint manufactured into the glass or is there tint film on the panes?    Again, thanks in advance for LDO help.

The seal between the inner and outer panes of glass has broken down, allowing outside air, along with any moisture and dust contained in the air, to enter. Temperature and altitude change 'pumps' air in and out.
The solution is too either replace the whole window, have it repaired or to live with it.

Repairing requires the window to be removed, disassembled, cleaned and polished and then reassembled with new seals.
Various shops around the country have this ability.

Ed, do a search under 'foggy windows' in the 'Technical' and the 'Improvements' forums; there are many posts on this topic. Also, look at the Companion (link on the forum home page) for this topic.

A P.S. to the above: I had the rear window in my TK replaced at the factory; about $1100, as I recall. One of the side windows - the 'slider' - is also fogged. Currently, this is a 'live with it' situation. If I decide to have it replaced, I will head to RV Glass Solutions in Coburg, OR or Phoenix, AZ.

Here’s a quick YouTube on RV Glass Solutions.  https://youtu.be/9IhB71wJGRw

They didn’t mention whether their dual pane solution is as dark as LD’s windows, which I really appreciate, but glass can be tinted, I believe, to limousine dark if you request it.

After several days of fussing with this issue, we've decided to 'live with it' too.  The window is not exactly fogged, but when it's exposed to direct sunlight, the window looks very dirty.  If it gets worse, we put it back on the list of LD projects.  Nevertheless, thank you for your guidance and window education.

Btw, this is the place we were considering to do this work.  RVFogDr.com  They received a solid recommendation from another company in Texas that I highly respect.  Perhaps this resource might help others in this part of the Country.

I thought this product was interesting:
This kit will remove condensation, mist or fog from double glazed sealed...

Their intended application is to drill the glass, which won't be happening with tempered glass.
But you could drill the spacer, not the glass.  Of course, then you're in for re-install, so you might as well source a rebuilder if you can find one.

Even if you could drill a hole into glass, the leak would not be sealed.
The product's reviews are not too encouraging either.
Wish it worked, our LD has a fogged side window too, it looks very dirty, in the right light.

I may have asked this question in our previous discussions so forgive me, if so. 

This wasn't an issue on the older (80's) LD's and I find it a bit troubling that this newer, supposedly better, window technology that LD uses has problems after less than 10 years of use.  Do other manufacturer's have this problem or is this a Lazy Daze exclusive?

All dual glazed windows, in homes or RVs suffer from this problem. The rubber seals, between the layers, breaks down.
Pre-2003 LDs have dual-layer, tempered safety glass and do not suffer from this problem.
Our 2003 LD's fogged window did not show itself until it was 13 years old.

LDs before 2003 had single pane windows; ‘fogging’ wasn’t an issue. Sealant between panes in the earlier rigs tended to shrink and crack more than later model years, but, as far as I know, no model year is immune to the potential of fogged dual pane windows.

LDs that are less than 5 or so years old are likely have many fewer incidences of fogging, I suspect less from any improvement in sealants than from less time and numbers of miles being shaken and rattled on the roads.

There’s no way to prevent window fogging of dual pane windows, as far as I know. ☹️

Caused by a leak...try lowering the humidity in your rig. If you could run a de-humidifier it might help. try to keep the relative humidity below 40% until the window is fixed.

I live in a low humidity area and have seen several examples of windows fogging in RVs stored in the desert.
We experience single digit humidity many times a years, it has no effect on removing the fogging.
The term 'fogging' usually describes the mineral build up left inside the glass.
Once a window has suffered this condition, there is no easy cure.

Once the seal is failed, air is 'pumped' in and out of the window's sealed area as the temperature and/or altitude changes
The window needs to be disassembled to clean and polish the dirty glass, before resealing.
Under some conditions, the mineral build up etches the glass, requiring replacement of the glass.

    I have an appointment April 12 in Phoenix at RV Solutions to have a window repaired under warranty.  I had 5 windows redone last fall, and one rear side double slider has failed.  Water is actually pooling between the panes of glass.  2005 MB 27.  Hopefully will be resolved, and the other four will continue to look as good as new.

The most interesting thing mentioned in the Amazon product listing above is that the residue from the humidity control chemicals can permanently etch the glass. Now permanent may just mean that their methods won't clean it off, or that no amount of cleaning, including polishing with abrasives, will address it.  Pretty sure it's the former and not the latter, but in any case, leaving it unaddressed long-term appears unwise.

Wonder what filling the void with mineral oil or some other transparent, non-freezing liquid would do? Bye-bye insulation qualities, of course.  Definitely don't try this at home! :)

2000 model for me, so just solid glass. Chilly but clear.

"2000 model for me, so just solid glass. Chilly but clear."

I believe your glass (windows) are not solid glass, rather safety glass - two panes laminated together. "Laminated glass is produced by sandwiching a tough plastic inner layer made of polyvinyl butyral in between two pieces of glass. The three materials are permanently bonded together to form one solid unit. The inner layer is invisible to the naked eye, and forms a chemical and mechanical bond with the glass. Laminated glass cuts as much as 99 percent of UV radiation penetration. Industry professionals commonly refer to it as "safety glass." Businesses that have a street-level presence use laminated glass for their exterior windows. If broken, the shards of laminated glass will adhere to the inter layer, versus shattering outwards. This property is one reason why laminated glass is often used for automobile windshields."

Someone please correct me if I am wrong.
