While you are waiting on the new windows, you may want to confirm that your Jayco service warranty claim has identified the correct "frameless" window manufacture for replacement(s).
I had all my vertical wiper seals shrink on my "frame" style windows and my dealer processed the Jayco service warranty claim based on Lippert Components (LCI) windows. The same claim was also based on replacing the windows thinking that the seals weren't replaceable.
I felt the seals could just be replaced and after some investigating I found my windows were actually manufactured by Cleer Vision Windows (manufacture name on corner of window)..., and Cleer Vision Windows actually had a how-to video (with correct seal #) on replacing the seals. My dealer re-submitted the warranty claim and I now have all new seals installed by my dealer.
Just food for thought..
