The guide pin, which opens the crisper/pantry lid, broke off. It is integral to the end cap.

First, I removed the drawers at the bottom of the fridge and then I removed the three hex head (7/32) screws that hold the end cap on. Then I disengaged the slider which connects to the temperature control for the pantry drawer. Then, unscrewed the drawer slides with a Phillips from the old end cap. Also the slide push rod has to be disengaged from the clips on the back of the endcap.

Then, I reinserted the push rod to the new end cap and reattached the drawer sliders and the slider itself. At this point I realized I SHOULD have unscrewed the temperature slider at the back where it covers the cold air outlet. The screw had slipped out. I replaced it with a slightly larger wood screw. Reinstall the drawers, all done.
