Flashing Alarm

Ford Ranger XL 4×4 horn stopped working months ago, alarm now make no noise, but the lights flash?

I checked fuses inside the door and are all very good. Weapons alarm, but no sound when it does, or if I try to activate the panic alarm no sound, just flashing lights. Suggestions?

Most of the time the alarm is connected to the horn to sound and whether the horn is a pity that you do not hear anything.
