The switch is easy to replace. The steering wheel doesn't have to be removed.
First you remove the small cover between the steering column and the instrument cluster. It just pulls off. Next you unscrew the tilt column lever. After that you remove the 3 screws that hold the upper and lower steering column covers and remove the lower cover. With the lower cover removed you can remove the ignition lock cylinder. To do that you turn the key to the run position and then with a small pick or screwdriver or nail you push in the "button" that holds the lock cylinder in. It is on the lower side of the lock cylinder housing. It's easier to see that for me to describe. Then you remove the top cover. With the covers off you can now see the multifunction switch. There are 2 connectors on the back of it and 2 Torx head screws on the side where the signal light lever is. Remove the screws and connectors and the switch pulls straight off. Like the manual says....reassemble in reverse order.
