Disassemble the plastic lid that hides the fuse box. Take both the wiper switch and headlight knob off by inserting a small pick into the indentation you can see on the backside of the knob. the black plastic panels on both side of the steering column come off with mostly clips. Take the left one off first, and you'll find a 7mm screw (or torx #15) that holds the black plastic trim piece to the right of the column in place. It will all pop out w/ a screwdriver. Once this is all removed, take a 15mm socket and an extension and remove the 2 bolts that hold the steering column in place. They are bolted into an aluminum piece that holds the column in place. You may beet to remove the 4 bolts holding the aluminum piece to the column to give yourself more access. Use and 11mm wrench to remove 2 nuts that hold the switch into place. It's about half way between the dash and the firewall, bolted directly to the top of the column. You can now pull up and remove the switch. Use a flathead screwdriver to release the connector tabs on the right and left of the connector. Install is reverse- Good Luck! Disassemble the plastic lid that hides the fuse box.
