What Causes a Car Horn to Stop Working?

[DelJace]

The reasons why a car horn may stop working include: 1. Broken or disconnected power circuit to the horn; 2. Poor contact in the horn button; 3. Burnt or excessively gapped relay contacts; 4. Excessive air gap in the horn's armature; 5. Open circuit in the horn's magnetic coil; 6. Water entering the horn during car washing. Solutions for a non-functioning car horn are: 1. Restart the vehicle; 2. Check for faulty wiring; 3. Replace the amplifier. Precautions for using a car horn include: 1. Avoid getting the horn wet during car washing, and dry it promptly if it gets wet; 2. Do not press the horn for extended periods, as this can cause premature burning of the horn contacts.
