After taking the two vegetable drawers out from above, the glass shelf, the pantry drawer and the cross support for the glass, you can get to the two recessed hex head screws holding the end cap. You will need to transfer the metal drawer slide to the new cap, but it doesn't need to come off first. When the end cap is loose, gently rotate it toward the front. Once the humidity control slide is at 90 degrees from the back of the refrigerator, the tab holding it in place will slip out easily. Once outside the refrigerator, the slide needs to be disassembled in order: 1) on the back side, you will see a small bump. This is just to keep it from falling out. Pull the slide out so the bump clears the unit. Then you can unsnap the main humidity housing so you can put it on the new cap 2) rotate the slide so the tab holding it around the corner to the next piece disengages. 3) slip the slide from under tabs on the end cap, and rotate it so the next tab clears the control slide that is on the outside front of the end cap. 4) gently spring the snap on the control slide so you can snap it into the new cap. 5) detach the metal drawer slide and reattach it to the new cap. There are two screws - one at the back end and one toward the front that you can get to by pulling the movable portion of the slide forward, so the access hole lines up with the screw. Transfer the reused parts and reverse the order putting the slide components back, around the corner, and push the humidity slide into the back housing so the bump goes back over the spot that retains it. Reinstall by having the humidity slide at 90 degrees again, engage the tab and gently rotate the end cap assembly back in place. Put the two screws back and all the shelving. It took longer to write this than to do it. The hinge pin on the new end cap is a better design with more plastic ribs for strength.
