I posted earlier that I tightened my vent windows, I received a couple PM's asking how so I figure I should make the available to all
Anyways my drivers vent window would flop close going anything above 20mph, the passenger was great.
When you open the window you will notice two holes in the bottom of the gasket. The green circle has the adjuster in it. Red circle is a mystery to me.
Take a 4mm allen and find the adjuster. Righty tighty lefty loosey
I've read that if you over tighten in it will crack a plastic piece... be careful
