2008 Lexus SC430 Horn not working
What is wrong with my horn on 2008 Lexus SC430? The weirdest thing is that every now and then, the horn will not work on straight steering position and it's work when I turn a steering wheels on 45 degree angle.
I've researched, it is the fuse, relay or spiral cable went bad?
Please help!!! Does anyone know what is wrong? Thank you...

Definitely not the fuse nor the relay. The only thing left is your horn switch and/or your harness. From your description, I think it’s your harness. Others can chime in.

From your description it’s the spiral cable assembly in the steering column. It’s a simple, but tedious repair. Here’s a you tube video:
If you take this on, battery disconnection is ABSOLUTELY NECESSARY! Always be careful around any yellow connectors and cables, they are associated with the airbag systems.
