Sliding window falls off when open

[Nels]

Hi there. I have a 2018 T6 VW Transporter. I use the sliding rear window regularly so my dog can get some fresh air. For about the last year it keeps falling out when you open it? Obviously now I keep it closed but would like opinions on options on getting it fixed? New style of window? Redo seals?

Somebody had a warning thread about a similar issue, try a site or Google search.

I would get it replaced with an aftermarket window, either a cheap recessed slider, or the THQ flush window if you want to keep the look.
