shit i think my window regulator died

well today i was rolling down my passenger side window in the front and POP! halfway down. WTF! so i quickly rolled it back up and the glass towards the B pillar moved foreward. Luckily I got it back on track but now I cant roll the window down without the glass falling off track. Would I need to replace the white clips that hold the window on or the entire regulator istelf? The motor still runs.

Pop the door panel off and take a look. The plastic "slider" pieces may have worn out or their metal retainer clips may have somehow come out. If the regulator arm pops out of plastic slider, just replace those. They should be $4 or so a piece.
