What problems can be caused by a faulty Horn?

Horn not working

When pressing the horn on the steering wheel no sound comes out. Sometimes there is a very weak sound from the horn.

Horn sounds strange

When pressing the horn the sound isn't as it used to be, the sound can be weak and sound more screeching than before.
