2002 Buick Century Master LockOut(for power windows) issue

2002 Buick Century.
I just bought this car and love it so far, however, on the driver's side power window controls, where the "lock-out" button is, it seems to be broken. It used to "click" when you adjust it and now it just flops around loosely. So now no windows can be put out down unless the driver does it, which is not a HUGE deal but is a bit inconvenient. I'm not a big car buff or anything but I am assuming its a lot of work it get at it or is there an easier way? Or am I better off just leaving it alone?
Thanks, this is my first post so be easy on me!
