My horn hasn’t worked since I have owned the car. I just put a new horn on the car and tested it, it works. I then pulled the steering wheel and tested the two studs sticking up out of the steering column, it still works. But now when I install the steering wheel it won’t work. I have tried jumping it from the studs on the steering wheel to the top piece on the wheel, nothing. I don’t know why it won’t work thru the wheel, any suggestions???
