Question about 2008 Scion Xb
Removing the fuse turns the horn off, so its not a short to power on the relay output side. I have also disconnected the wiring at the front side of the clockspring, as well as behind it, horn continues to blow when the fuse is reinstalled. Ohm'd wire from back of clockspring to ground, 20 million ohms of resistance, so no short to ground. All thats left really is the fuse box and relay, the dealer says the relay is internal to the box.

most new cars have what is called a clock spring be hind the steering wheel.this is a flat ribbon cable like what you would Se in a computer.what can happen when the ribbon is damaged is the horn can quit working.the cruse control .and the air bag light will come also.but most likely one of the problems will occur.but over time the other problems start happening also.so are you sure you are getting power to the relay .use a volt meter on the terminals under the relay and have someone to push the horn button.this will tell you if you are getting power from the horn button.
