Horn Relay: Description and Operation
SYSTEM OPERATION
The horn relay is a electromechanical device that switches current to the horn when the horn switch on the steering wheel is depressed.
The horn relay is located in the relay and flasher module. The relay and flasher module is mounted to a bracket that is secured to the cowl side
inner panel behind the right end of the instrument panel. The relay and flasher module is accessed by removing the glove box bin.
If a problem is encountered with a continuously sounding horn, it can usually be quickly resolved by removing the horn relay from the PDC until
further diagnosis is completed. The horn relay cannot be repaired and, if faulty, it must be replaced.
