Q&A

It sounds like the "clock spring" coil in the steering column has an open circuit. The "clock spring" is an electrical circuit that is wound in a coil and is installed just bellow the steering wheel. The "clock spring" allows the electrical circuits for any electrical components in the steering wheel - in your case, horn, air bag, and cruise control switch to continue to function while the steering wheel turns. The clock spring coil is designed to wind and unwind as you turn the steering wheel. The clock spring must be centered in order to wind and unwind properly. It could be possible that your steering wheel was turned while the steering shaft was disconnected during your steering rack replacement. With the clock spring off center, when you turn the steering wheel to full lock in one direction or the other it is possible to damage the clock spring.
