Horn Issue with 100 Series

[ghong14]

Hi fellow LX enthusiasts!

Recently, I noticed LX 470 horn is working sporadically and it seems to change based on the telescopic control I make on the steering wheels.

In another word, if the horn doesn't work I simply adjust the steering wheel with the telescope control and the horn comes back to life. Also, I noticed that the horn doesn't work when the steering assembly is all the way or all the way out.

Any experience with this? Also, what is the connector under the steering wheel that I should look at to make sure everything is tight?

Thanks!

I am having a silmiliar problem. If the horn does not work I move the steering wheel and it then works. Any recommendations?

My horn sounds like someone stepped on a mouse is this normal?

Which horn upgrades are plug and play and fit in the stock spots?

If I’ve been reading these threads correctly, can I assume if I get no sound from the horns, and no click from the Underwood fuse box, that the problem is in either the wiring in the steering column or in the grounding of the steering wheel pad?

Lexus horns plugged right into the factory connectors of my 80... here's a link from the 80 section

@Luke111 , Are you talking about the horns you bought on that link, where you have the pic with the p/n's, or are you talking about the @Akella horns on page 1, the JDM premium?

Gents,
I have a 2000 lx470, my horn does not always work. I normally need to move the fiddle with the tilt and telescope to get it to work. Now this vehicle has had the telescopic motor changed 3 times, the ignition done, the Steering wheel straightened because it was off to the left. Any recommendations on what to chase? Clockspring ring?

So dealer had fixed horn issue, they said they had to fix a ground wire. They also said I needed a new horn pad but horn works in every position. Everything was fine until I disconnected the battery. My horn was not working after that, moving the steering wheel got the horn to work. Anyone have a recommendation on what I should check to get the horn working consistently ?

Sounds like the clock spring in your steering wheel may be bad, if moving the steering wheel gets it to work or not.

Were you able to find a fix for your horn issue ?

My son's 2000 LX470 recently lost its horns. Plural. The fuse was fried, and I replaced it, hoping there wasn't a bigger problem somewhere else. Still no horns after a new fuse.

Turns, out, both horns are dead. Still no idea why. New ones are on the way from the land of the rising sun.

BTW, can someone please explain why these fuse prices are based on the price of gold?

Had no horns recently. Did you try jumping the relay (there's a fuse and a relay)?

By jumping I could figure out that everything the fuse box was working fine. Took off the steering wheel airbag, cleaned, checked for ground and so on. Nothing worked.
Eventually got a new clock springs and the 20min job brought it back to life!

So I can only suggest:
- remove relay and jump it with a wire (there are 3 contacts, not sure which 2 I jumped but you test all combos within 5s )
- if horn works with jumping I'd get the $12 relay first
- then perhaps clocksprings/ new horns
