Console cover is 4 clips, one at each corner. Cup holder comes out with it and it's attached to center console via a few philips screws.
If you're just after the one switch than you can pry up the the cover, unplug wires leading to button, press sides of button from the bottom to release clips and push button out from the bottom.
I've done this a couple times recently. I'd recommend unplugging all the switches and pulling entire cover off. Great opportunity to clean all the switches really good and vacuum if needed. I was surprised at how much crap was under three. Not sure if mine had ever been opened by previous owner.
