How to remove horn relay - 1997 Hyundai Elantra

Horn The horn system consists of the following components:

• Horn switches (part of the steering wheel)
• Clockspring
• Horn relay (part of the smart junction box [SJB])
• Horn

For removal and installation of the steering wheel, refer to Section 211-04 .
For removal and installation of the SJB, refer to Section 419-10 .

check horn relay in relay compartment under the bonnet of car
suspect horn relay fault or horn button on steering wheel

Check for a bad connection at the horn button.

The horn switch is stuck. If you want to disable it remove wire from horn or remove relay. You will need to replace horn button

Could be a wiring problem or the clockspring in the steering column.
You would need to pull the steering wheel and test the circuits.

First check for faulty horn relay. If OK then check Horn pad, it is an earth switch and may be dammaged. Remove horn pad and check for wire off and contacting to earth or short to earth . If problem still exists with horn pad removed then the wire from horn relay to steering column is earthing out

if you check the wire that comes from the horn button to the relay for voltage when the horn is pushed and have voltage then you have a bad relay,if not then you probably have bad contacts in the horn pad area or even the clock spring itself.

My guess is, it is telling you the horn relay is absent/defective? Put the relay back. It may be the relay is the problem or maybe not. Look for a code.

Remove and replace the Horn Relay. There should be a Spare Relay of the same Type (Size and Shape). OR
Switch out the suspected Horn Relay with another Relay in the Fuse/Relay of the same Type (Size and Shape) that is known to currently work. After the switch check the operations of both the Horn and the function you switched out. If the Horn works and the other function doesn't work any longer: The Relay was bad and needs to be replaced.

The dealer can hook up his diagnostic tool and retrieve the fault code. -------------- SECTION 413-06: Horn 2003 Expedition/Navigator Workshop Manual DESCRIPTION AND OPERATION Horn Horn components include the following items:
