Where is the horn relay of Volkswagen Santana located?

[CalvinLee]

Volkswagen Santana's horn relay is located in the relay box in the engine compartment. Horn Relay: The horn relay controls current with current to protect the switch. Since the horn requires a significant amount of current when operating, if the switch directly controls it, the switch would frequently burn out. By adding a relay, the switch controls the relay, and the relay then supplies power to the horn, preventing the switch from burning out. Precautions: When washing the car, be sure to prevent the horn from getting wet. If the horn gets wet, dry it with an air gun as soon as possible. Try to avoid pressing the horn for extended periods, as this can cause premature burning of the horn contacts.
