z3 door window leak!

[salamancaz3]

i recently discovered there's a slight air/water leak coming from the small triangular driver side window. it looks as if its coming off the rubber trim (in the middle of the 2 windows), at the top. its not too bad but i'd still like it to be fixed. do i have to replace this? can i just adjust it? if so, how? any advice is appreciated. thanks in advance

Have a closer look at the guide-trim and ask yourself if you think it has perished !
I would replace it as once you start repairing these items, it will only be a temporary fix...

where can i buy this guide-trim? can i order it from any auto store, like auto zone, o'reillys etc.? also is there DIY instructions?
