Help adjusting quarter windows

I didn't mention vert before because the odds were yours isn't. Now that I know...
Yours is in some ways the easiest quarter window to service. Depending on whats wrong of course.
There are soooo many adjustments available in a vert that others don't have.
The more it was disassembled the more time it takes to get it right again.
I can only wish you good luck with it.
