First time posting so sorry in advance if I did something wrong. The horn in my 84 has died and I know it's the unit itself because it keeps blowing fuses but the button on the steering wheel works and the relay looks fine. The horn gives a kind of wheeze before it blows a fuse so I know the connection is fine. I know the horn is located in the front bumper and I know how to take it off. I just need to know about replacing the unit itself. Can I just go to autozone or something get a horn and put it in? (I understand that the mounting bracket and the plug would be different) or should I track down an OEM horn? or is there an aftermarket horn that the community swears by? I've had the car for awhile but I'm new to the community so I'm just trying to see what the more experienced owners have to say before I start taking my car apart.

 

There are two horns. One on each side. It could be one of the two shorted out. I would unplug one, replace fuse, and try again. I doubt both are shorted out. I pulled one from a junk yard and it worked great. $4.
