The tcs and check engine light came on dashboard along with the wiper blades begin moving even though the wiper blade control switch was in the off position. Every button, horn, and the wiper blade/ turn signal control arm on the steering column will not work. Fuses appears to not be blown. Nothing with turn off the front wiper blades. All other electrical buttons and the dashboard cluster works with no mal function. The hazards work fine as button is below radio and not on steering column. This brings safety question of no turn signals at night and possibly airbag might not deploy if rest of the electrical switches and buttons are not functioning on the steering column only. This happened initially in motion on a city street after getting off a highway and turning into a parking garage. Millage is between 116000 and 117000 miles.
