The clock spring has 3 connecting points i think, it connects the airbag and the horn to the car. that could be your culprit. I had a similar problem when a mechanic tried to remove the steering wheel without unplugging the clock spring.

The strip broke, but luckily i managed to solder it back again. But it's giving me problems again, i am still looking for the clock spring to replace it.

Hope that helps.
