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.
