Totally out of the box: Apparently the button on the stick moves as supposed, but does the initial micro switch underneath it work? Sometimes they get stuck, sometimes they shortcut. If you can feel a click, then it's not stuck but there may still be dirt preventing it to do its job. A screwdriver, a can of non-lubricating electric cleaner spray and a pair of steady hands might help, plus a large-ish table with good lighting.
