A: When a vehicle's clock spring goes bad, a driver will likely experience a non-functional horn, an illuminated airbag warning light on the dashboard, and malfunctioning steering wheel controls for functions like cruise control, radio, and phone. You may also notice a clicking or grinding noise when turning the steering wheel. The most critical issue is the potential failure of the driver-side airbag to deploy in a crash, making the vehicle less safe.

A: In vehicle steering systems, a clock spring or clockspring is a spiral-wound special rotary electrical conductor which allows a vehicle's steering wheel to turn while maintaining the connection between the airbag mounted in the wheel and/or the vehicle's horn and other devices, and the vehicle's electrical system.

A: While you can drive with a bad clock spring, it's not recommended because important safety features like airbags and horns won't function properly.

A: Replacing a clock spring is an intermediate DIY job that can be done by a mechanically inclined person, but it requires careful handling of the airbag and precise alignment of the new part. While it's not overly complex, the process involves disconnecting the battery, safely removing the airbag and steering wheel to access the clock spring, and then carefully installing the new one in its centered position. If you are not comfortable with the safety aspects, particularly involving the airbag, or if you lack the necessary tools, a professional mechanic is a safer option.

A: Clock springs can last the entire lifespan of a vehicle, but they can also fail after just a few years, depending on usage and manufacturing quality. Factors that contribute to failure include normal wear and tear, extreme temperature changes, and steering wheel over-rotation, which can damage the internal ribbon of wires.

A: A clock spring goes bad primarily due to normal wear and tear from repeated steering wheel rotations, which damages the ribbon of wires inside. Other causes include steering wheel over-rotation (often from a damaged steering linkage), which exceeds the spring's limits and snaps the internal components. Less common factors are a vehicle accident that can overheat and damage connectors, or manufacturing defects.
