how to take wiper switchout of cluster??

The shaft of the headlight switch is held in place by a spring loaded button located on the back side of the switch. Pull the shaft out to the on position and while holding the button down, you can pull the shaft out of the switch and gain access to the nut holding the switch in the dash. You may have to slide the shaft back and forth a little while holding the button down firmly but it will pull out the front. I think the release button is on the top side of the switch right on the back side of the bezel.
