A weak, intermittent, or silent horn can be a concern even when no dashboard warning appears. Many vehicles do not provide a dedicated horn-failure light, so do not depend on the instrument panel to report the problem.
Note whether the horn fails consistently and whether other steering-wheel controls are affected. Avoid dismantling the steering wheel because airbag components may be nearby. Contact 12th Street Auto Care Center in Sioux Falls to discuss the symptoms and an appropriate next step.
