You've probably lost one of your horns (there's a high pitch and low pitch horn)...or corrosion has gotten to the electrical connector...which could mean you need a new one, or it could be as simple as cleaning it (as well as possibly cleaning the non working horn out). They are located in the front left wheel housing:

H2 = left horn & X132 is its electrical connector / H3 = right horn & X133 is it's electrical connector


(#5 in diagram below is X132 or X133 identified in images above)

Or perhaps your horn relay (K2 in image below) has gone bonkers:

Time to do some discovery.
