Default Knick sound from horn relay

Hello,

I changed the horn in my Aveo to Roots Windtone. I notice that there is a "knick" sound soon after I release the horn. Possibly from relay. This was not there with the stock horn and it is a bit nagging. What could have gone wrong?

does it come when your stereo is playing (from the speakers) or even when the stereo is off.

Hi Navin,

It doesnt come from speakers. It comes everytime horn is used (even without the key in)

Seems to be pretty normal to me. My horns (roots) are also wired through a relay, PMP make. The sound you hear is the contacts or relay points opening and closing. If the relay is electronic, you wont have this sound. Get it checked by a local mechanic if u must.

The noise is ok, but a bit nagging as it is clearly audible after the honk. Could anyone explain technically what happend between changing horns that made the relay point opening/closing audible?

I too have a similar problem. I hear a slight kir kir (electric spark) sound from the speaker only when I press the horn from the top right spoke on the steering of my OHC. It does not come if the horn is used from any other contact point.

The horns are fitted well with the relays (Red Grill and Nautilus). What can be the problem, do I have to get the steering connection checked?

My problem is different as the sound is not coming from the speakers.

Nirmal,

I think it's perfectly normal and OK and I see no reason to worry about it.
Possibly the horn relay was changed with the horn, or the horn itself has a relay built in. Regardless, no need to worry about it.

Precisely... and if the noise is irritating, its time to invest in a nice ICE setup.

It already is nerve racking listening to all the traffic noise around you. Better get some good ICE and enjoy your drive.

Maybe the OE horn did not have a relay & that is why you did not hear it.

Try relocating the relay to somewhere in the front so that noise is under control.

Is the NVH of a Palio so bad that one can hear a relay clicking inside the engine bay?

Or is the relay installed under the dashboard??!!!
