I think this goes in here?
So ive noticed a bit of green mildew on the headliner above the back ext cab window on my truck. While having to ride back there today, i decided to touch it and it was wet. Ran my finger along the whole top edge and noticed the rest was damp as well. Obviously the window seal is leaking. My question is how do i fix it? Also it is a non slider window. If I need to pop the window out to re-seal it will a slider window just pop right in? TIA
