How to repair mitsubishi

Check the fuse first! if it is ok, then remove the wire from the horn and hook a test light to it to see if there is any power to horn under hood. push on horn button while checking for power to horn. if there is power to horn, then either the horn or ground is bad.on most cars, horn is grounded by the car body. if no power to the horn and the fuse and wire is ok, then its the horn button. good-day! to test horn, disconnect the horn wire, run a wire from battery positive to the horn connection just touch the horn connection with the wire from battery. if ok it will work.

Not being smart but get a manual or youtube it. You need to remember that the air bag is located near the horn device. You can be hurt by the bag if it inflates.
