How to replace a car horn
A working horn is an important feature for every car. The horn serves as a safety feature and is required to pass most government inspections.
Not having a working car signal is dangerous and can prevent your vehicle from passing the state inspection. Thus, it is important to understand how a horn assembly works and when it may need to be replaced.
When the horn button (located on the steering wheel pad) is pressed, the horn relay is energized, allowing power to be supplied to the horn(s). This horn assembly can be tested by energizing and grounding directly to the horn. If the horn barely sounds or does not sound at all, it is defective and must be replaced.
