I've installed a airhorn couple months ago but without the relay that comes with it. So i ran it without my stock horn. I recently washed my car and then my horn didnt work. Then it would come back on and off. And now it doesn't work completely. I've checked the fuses and the stock horn relay makes a clicking sound when I push the button. I hooked up a test light to the horn wire and pushed it but the light doesn't go on. What is the problem? What should i do?

 

You will probably need a multimeter to really check this. The relay clicked, but you need to make sure that voltage is being passed. I think the relay is dead.
