Hello
I took off the air-bag block on the steering wheel to see if the connection is good, I changed the steering wheel thinking it was the buttons on the steering wheel that didn't work, I changed the horn, I put a tester on the wire and I pressed it with sound.
the wire finally the wires from the steering wheel are linked to other wires to go to the horn or not? well in the fuse box I guess the horn is connected with some accessories but which ones?
thanks
