Volvo upper sleeper winow

If it’s the later upper window with just the vent, you’re going to have to replace the whole window.

The rubber seal isn’t sold separately.

 

You can check dealer scrapyards for replacements in better condition. Both my local dealers have carcasses sitting out back.

 

They’re glued in with silicone and clips, you’ll need to cut the silicone out from the outside so they’ll come out.

 

If you have issues with them leaking when they rain, I do as well in my 2013. I am going to do like most I have seen and just slap some of that flex seal or flex tape on them until I get around to finding the time and energy to replace the windows. I never use mine. But I am sick of when it does rain at night when I am asleep getting splashed on the head with rain drops.
