I have a horizontal sliding window in my 2021 that is leaking. Can anyone tell me how to Replace the weather stripping in this window? It's one of the exit windows on the slide out.

I have a horizontal sliding window in my 2021 that is leaking. Can anyone tell me how to Replace the weather stripping in this window? It's one of the exit windows on the slide out.

There's a video on LCI's site https://support.lci1.com/windows that shows replacing the vinyl nosing on a sliding window.
For that one, the Kinro 8800 series, the vinyl nosing has a lip that's pressed into the frame.

My rear slider's nosing tends to shrink after awhile in the sun light.
