@nazarhakeem check the horn itself first. Just apply some voltage directly from the battery and just touch the connectors on the horn. If the horn now works, you know the issue is with the wiring. Next check the horn relay and see if you have power on that. If so, you need to check your horn button and make sure that it works properly. We will need to know your exact model and year so we can assist you further with the wiring and locations of the components.
