I'm redoing some doors for a coworker's Jeep and the post with the spring on the bottom of the vents is not attached to the glass frame. Every other vehicle I've worked on has the post part of the frame so the spring helps hold tension on the frame & keep it in position. I'm guessing these have broken. I've been trying to find pictures online of a disassembled vent window but not having any luck. Does anyone have any disassembled pics or can confirm that the stud should be attached to the window frame?
