Question about 2007 Toyota Yaris S
I have replaced the bracket of the steering wheel (The point of contact that closes the circuit) And the 3 plastic pushback springs, since I believe that was the original problem, but now the fuse still pops every time and I am at a total loss. My inspection is out of date and now I have a ticket for it, if I can fix it before the date in a week I can nullify the ticket. Any help would be greatly appreciated, thank you.
Turn key off, locate and unplug horn, install known good fuse and or ckt. brkr, push horn button, if fuse does not blow replace horn assy. If fuse blows you have a short on circuit wires. A well trained electrical tecnician should have no problems finding it, plus you'll need schematics. Good luck!!!

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

The car fuse box is usually found in one of two places: usually near the bottom of your dashboard as you move closer to the foot well or, on some models, under the hood. If you are having trouble finding the car fuse box, have a look at your car manual.

YOU HAVE TO TAKE OFF THE DOOR PANEL ON THE INSIDE OF THE HATCH, IF IT WONT OPEN YOU HAVE TO DO IT FROM THE INSIDE, THEN THERE ARE 3 10MM BOLTS YOU TAKE OUT AND THE HANDLE AND PLATE LIGHT BRACKET WILL COME OUT AND YOU CAN REPLACE THE HANDLE... FYI MOST TIMES THE HANDLE BREAKS BECAUSE YOUR ACTUAL LATCH IS RUSTED OR FROZEN SO YOU MAY NEED TO REPLACE BOTH!!

Usually the wire from the steering wheel is Green w/Red and the wire to the horn from the fuse box is White. There is only one fuse, sometimes shared with the emergency lights. Check to see if there is power to the horn itself with a volt meter.

If the horn works with direct connection, and fuse, relay, and circuit breaker are all good, it's the switch in the steering wheel. If it is anything like the chrysler auto's, the switch and the air bag module is all one unit, can't replace just the switch, the whole thing, and it's about $700 to $800 for those units, at least it is here, and can only get them at a dealer.

Tips for a great answer:
If the test lamp illuminates, refer to the Horn Test.
Ignition OFF, disconnect the inline harness connector C275. Ignition ON, test for B+ between the horn relay control circuit terminal B and ground.
If less than B+, test the control circuit for an open/high resistance. If the circuit tests normal, replace the underhood fuse block.
Momentarily connect a 3-A fused jumper wire between the control circuit terminal B and ground. The horns should work.
If the horns do not work, replace the underhood fuse block.
If all circuits test normal, test or replace the horn switch
