The horn stopped working. Toyota verified it is the electrical behind the dashboard, which will cost $475. 00 to repair. I was on the interstate highway 89 when the car I was passing started veering into my lane. I went to use my horn and it did not work! very scary situation.
Horn only works when the steering wheel is turned to the right or left and won't work when the wheel is straight. No matter if the car is moving or not the problem is fixed by replacing the clock spring, a lot of people had this issue in Corolla (2010 -2012).
