Car horn
It's sounds that the horn is bad to check to see if horn is bad is to a get voltage meter then take the wire off horn then put red lead in the plug then to body of car then go push the horn , make should put meter where you can se it. If you don't have a meter you can take a wire from the horn where you pulled off the plug if horn don't sound it's the horn
SOURCE: Horn blows fuses
The most common cause of this short is the horn coil, replace the horn and the problem will be fixed, a quick test is to disconnect the horn and press the horn button, if the fuse doesn't blow the horn is the problem.

save yourself the hassle , buy yourself a momentary 12volt switch drill a nice clean hole on your driversside dash and re-wire your horn to it, all the screwing around you'll do to figure out why toyota makes cheesy horn contacts you could have your problem fixed..
on one side of the switch you should run a wire that is a 12volt switched +
on the other side I would run another side run a new power wire to your horn
leave your horns stock ground and just replace the HOTLINE ..
you could even go as far as installing a la cou ca racha horn to bring back that 70's Lowrider feel lol

Remove the wire connector from each horn and attach a voltmeter or test light. Have a helper push the horn button while you check for voltage. If there's no power getting to the horns you have to work your way back to the relay checking for shorts. If there is power try holding the horns metal mount against a good ground like an engine bolt or the sub frame. And with wire reconnected have your helper try the horn again. If it sounds then clean rust away from mounting bolt and car (rad support or grill bracket), and look for a loose or broken ground strap to the rad support (from either the battery or engine). If both horns still don't work either they're clogged with snow or dirt (bring them inside to defrost or clean out), or they need to be replaced.

You have to first check for power to the horns. Remove the plastic panel under the hood on top of the radiator support. The horns will be there on the side of the radiator support. Hook a 12V test light or volt meter to them and press the horn button and see if you have power there. If you do its a bad horn if you don't then check fuse no. 5 (15amp) in the engine compartment fuse panel. If it is good then the next step is to eliminate the relay also located in the engine compartment fuse box. Basically how it works is the no. 5 fuse feeds both sides of the relay. You have a switch side on the relay that feeds the horns and a coil side which when energized by the horn button creates a magnetic field which closes the switch in the relay and blows the horn.
If you have no power to the horn and your fuse is good try swapping the relay with another one in the fuse panel if it still doesn't work then go to the connector located at the blower motor under the hood,there will be 2 connectors that run on top of the blower motor,the one you want is the bottom one of the 2. It will be a square 12 pin connector. Find the dark blue wire there and ground it if horn blows then it will be the clock-spring or the horn button itself.

horn is under the hood. usually right against the grill or mounted on fender well. fuses for horn can be under the dash, or in fuse panel under the hood.
