Volvo 780 upper bunk window

Old Volvos VNL 780 made between 2003-2007 have had all 4 sleeper windows openable. After 2008 Volvo replaced upper windows to fixed ones with vents.
Good question is: why did they redesigned upper windows if older were just fine? Well, a lot of 670s and 780s had issues with upper window seals and some water could get inside the bunk.

I don't know about aftermarket, but my friend found old style windows from junkyard and put them on his 780. They fit perfectly, make sure you seal them better than Volvo plants did.

Hope I helped

 

Typical.

Flunky...
Sir, the upper bunk windows seem to leak water. Should we design a better seal?
Superior Intelligence... Na. Just make it a fixed window and add a useless vent below it that won't let water in - or air for that matter. They are only truck drivers, after all.
