Not only is it a small glovebox, the door opening mechanism breaks easily. Fortunately, there is easy access to the problem by removing the side case, just like the fusebox cover on the other side.
In my case, the plastic post (which is unfortunately part of the glovebox itself, and thus would require replacement of the entire box) snapped off at the end of the screw, which holds a small gear that makes the box open slowly.
I hate to admit it, but I put the broken post back on and put in a longer screw through it and into the box housing, just short of coming through the inside. Namely, a 1.25" sheetrock screw. Is that wrong? It should be!
