Horn Relay
The horn relay switches the high current needed to operate the horn when the driver presses the steering wheel switch, protecting the switch contacts from direct current load. Signs of failure include: a horn that does not sound when the button is pressed, or a relay that clicks but passes no current to the horn. Replace the relay to restore proper horn operation.
