I replaced my car's horn 2 weeks back, the horn has good sound but sometimes while driving it doesnt sound or sounds very less and today it wasn't working at all but i parked my car for 1hr then drove it then it was working and when it used about 5-6 times the voice gets thin. Is this current issue isn't the horn getting proper current previous horn also got thin sound so i replaced with new it has relay also. Some times my hand gets touched to metal part of car inside it and i get a little shock. Once i got shock while touching the steering metal part but its very low shock but it is. What could be reason. Help me guys.
