Where is horn relay on a 97 Kia Sephia, also need to know location of the horns

Do you have a air bag light lit on the instrument cluster ? I ask this because , if the air bag light is lit , could be a clock spring problem . I know ,what the heck is this guy talking about . You have a air bag on the steering wheel ,the horn button is on the steering wheel . The clock spring is located under the steering wheel , in the top of the steering coulmn . It has flat wire tape in side that allows the steering wheel to be turned full left to full right , keeping the horn , air bag , an any other button's on the steering wheel connected electricly to the vehicle. Plus there is a relay , when you push the horn button it energizes the relay turning on the horns. Watch these videos , will explain a little better .

How cars clock spring works

The horn relay is located in the under hood fuse box .

It is unlikely the horn is the problem. We do not have a circuit diagram but here is what I do have:

HORN TRIGGER (-) LT.GREEN/RED Harness Coming From Steering Wheel At
Steering Column, when the horn button is pushed this should be a ground circuit.

The clicking you hear is the horn relay working.
I would locate the horn and insure the wiring is intact and the horn has a good solid ground.
Then while someone is pressing the horn button measure the voltage at the wire that attaches to the horn to ground. If you get 12v or more the horn is bad. If you don't get any voltage replace the relay

simple circuit, but can be hard if problem is switch in steering wheel. First check fuse and relay at fuse box. relay should click when horn button on wheel is pushed. If relay doesn't click, either button or relay is bad. If relay clicks, test for voltage at horn. You can use a simple test light available at the auto parts store if you don't have a voltmeter. If there is voltage at the horn, replace horn.
If relay does not click, replace relay to see if that fixes your problem. If new relay doesn't fix, you have a bad switch in the steering wheel or possibly bad wiring. cannot help you with switch as it's different on every car. any questions--let me know.

Visually inspect horn make sure its not corroded and wiring is on it tight. Then use a voltmeter and when horn button is depressed 12v should register on the meter. If 12v are there and horn doesn't sound the horn is defective. If 12v does not make it there then its either the relay or clock spring (located inside steering wheel) most likely. A visual inspection should pretty much do it with the clock spring (corrosion ,wear of contacts). Relay must have B+ going to it at all times and coming out only when horn is depressed. good luck

This may not be coincidental. You may have a faulty horn switch behind the steering wheel.

Horns have power to them all the time. When you push the horn button, you are completing a circuit by providing a Ground.


Before the horn gets it's power for the 2003 Pontaic GrandAm, the power goes through a Horn Relay. (Number 21 relay)

It may be a bad relay, horn slip ring contact button, (Located under steering wheel), or bad horn/s.

The horns are located up under the front air dam, tucked up close to the air conditioner condenser. VERY hard to get to.

either the horn relay is stuckor horn contacts are shorted in steering wheel.

Road rage haunt occurs when the horn is struck with a closed fust. just joking.

a very common cause of this problem is the steering wheel mounted horn button looses it's connection to the horn circuit due to a defective ribbon rotating contact under the steering wheel, the special clock spring shaped ribbon wiring harness is what allows you to turn the wheel and still have a connection to all steering wheel buttons and the airbag, to check this listen for a click when u press the horn button with the engine off, it will be faint but if u listen closely u will hear it, if u don't hear it u will ned to replace the Clock-Spring rotating contact under the steering wheel.

If your Air Bag light light is aluminated and The Cruise Control does not Work then the Problem is in the "CLOCK SPRING" this Component is Located Under the Steering Wheel and it requires the Steering Wheel to Be Removed.You Must have Complete Instructions on this Procedure or Injury Can Be the result.
