The windows still work from both the driver's door buttons as well as each individual door button when the lock button is in the "locked" position. Also, the lock switch does not appear to be stuck down; it moves freely up and down. I can tell when it is slightly raised or slightly pushed in, which is supposed to indicate a locked/unlocked position.
This may or may not be helpful, but I noticed from the owner's manual that, when in the "locked" position, all window buttons except for the driver's window button is not supposed to be lit up. That does not happen when my lock button is pressed - all window switch lights remain lit.
