You can leave the glass in (infact I have never been able to get the window regulator out without first removing vent window) and still do it pretty easy. It has been awhile since I have done it, but you have to lower and move back the corner of the glass that is in the way when trying to remove the vent window. I do this my removing the 3 screws that hold the vertical channel for the glass and weather striping inside the door. Then Temporarily pull the channel down and tilt the glass back and down out of the way. Then the vent window will come out with a little turning.

There may be another way to do it, but this is how I have done it.
