Removing the driver's door window

The regulator finally failed on my 2000 Mystique. I tried to separate the window from the regulator; but merely removing the two mounting bolts didn't free the glass. Can someone tell me what I'm missing before I destroy the glass trying to get it off the old regulator so I can replace it? Thanks.

Took me long enough (and a garage where I could get out of the wind); but I figured it out. Those little plugs aren't even mentioned in the OEM shop manuals, at least, not according to the chat dude at Dorman, who couldn't find any mention of them in the directions for removing the window from the regulator, so as to remove the regulator from the car, that he said he was reading from the shop manual.
