In today's video, you will see how to replace the horn on a first-generation Smart. First, ensure the vehicle is stationary to avoid touching hot or heated parts.

Lift the vehicle (you can use a ramp, as you need to work on the front of the vehicle) and locate the horn in the middle of the car. Remove it and proceed to install a new piece of the same type, paying attention to the power connectors. Once done, lower the vehicle and test if the installed piece works correctly, and if so, you are finished.
