If you take a stylus pen and leave it on the upper storage bin, the one just under the A/C controls, and close the bin, the pen will roll and fall in the gap behind the door. This will make it impossible to open the bin, since you have to push it to release it. Now the most interesting part is that once the pen is stuck, you don't know that is there, you just keep trying to push the little door and it won't budge. And the pen is not visible. What I did once I found out what the problem was, with the help of the little lantern, was to use a business card to push the pen back inside and release the door.
