how to take wiper switchout of cluster??

I've been told there is a special tool to do it best. I'm seeing Dan201 on Thursday afternoon, he has one and will use it to take it off for me.

Not sure what it looks like, but my nut is seized on there tight. If it's not seized I've been told that it can be taken off with a screw driver but you chance some damage!

Is yours on there tight or rusted?
