Q: Horn independently honks; fuse disengaged

asked by on August 15, 2016

My horn will independently just start honking. At first, the problem was intermittent, but now it has progressed into a continual problem. It happens whether I am driving or stationary. So, we had to disengage the fuse for the horn. I haven’t taken it to an auto repair shop and I’m wondering if this is something that I can fix myself. What should I do to fix this?
