The multifunction switch can be replaced easily. Remove the trim around steering column. There should be 3 or 4 phillips head screws going up through the bottom portion. The switch is held on by 2 t20 torx head screws. There are 2 large wiring connections on the back of switch. Unplug these and remove switch. Then install new switch in basiclly reverse order. There should be no danger in deploying the air bags.
Have codes read again and post exact code number that is retrieved. Exact code will give us a place to start research.
The soft shift in the gear selector may be a couple of small screws that have come loose where the shift cable is attached to the bottom of steering column. If these are tight, you may need to unbolt the steering column and let it fall down so you can check the shift tube bushings. Be careful if you do this. There is a small string that is connected to the needle that tells you what gear you are in. This will break easily.
