Horn: Description and Operation

Horn:

Vehicle is equipped with one horn mounted behind front bumper at the center. Operation of horn is controlled by a switch (horn button) located on steering wheel. Electrical power from positive side of battery is applied to a horn relay located in fuse box of engine room. When horn button is pressed, horn relay is energized, and electrical power is directed to horn. Circuit is completed by case-ground of horn, and horn sounds. When force is removed from horn button, springs force button upward to open horn switch. Relay is de-energized and horn operation stops.


Battery voltage is supplied at all times to both the coil and the contacts of the horn relay from the HORN fuse. When the horn switch is pressed, the coil or the horn relay is grounded through a clockspring.

The horn relay then energizes and applies battery voltage to the horn, causing it to sound.
