How do you adjust the vent window frame

I,m not totally sure, but if you remove the inner door panel, next to the splined shaft the window crank fits to, you'll see a jam nut and screw driver slot adjustment. This has a cam like dohicky, on the inside, that adjusts the up travel of the window regulator.

I'm following you, but the top of the vent window frame still would prevent the door window from going up because the window slides up in the vent window frame. I did not know about the regulator stop. go info. I need to raise the vent window frame upwards.
