- Step 1: Check for sound Check whether the horn makes any sound. If it does, the electrical circuitry is still working.
- TIP: Most vehicles have two horns, which sound at the same time. They are usually mounted to the radiator core support or behind the vehicle's grill.
- Step 2: Check horn Unbolt, clean any corrosion, and reinstall the horn if it does not sound. If the horn still does not work, run a jumper wire to it from the battery. If it still does not work, replace it.
- Step 3: Check fuse Check the fuse that controls the two horns if there is no sound from either one. If the fuse is burned out, replace it. Try the horn again.
- TIP: Check your car owner's manual for the location and type of fuse.
- Step 4: Check horn button Check whether there is any debris obstructing the horn button on your steering wheel that may be preventing the horn from sounding.
- Step 5: Check wiring Check -- or have a mechanic check -- the wiring attached to the horn, if all else fails. If it is damaged, repair or replace it. Now you can make some noise.
- FACT: Before 1910, bulb horns were widely used on automobiles.
