How difficult is it to replace a horn? My horn definitely does not sound as loud as it used to-- sounds only like two notes of a chord instead of three? Does this make sense? Once before during a really slushy snow storm the horn got quieter, I assumed it either shorted out or got packed with snow. Now it's summer and the horn has suddenly gotten much softer sounding, and like it is only coming from the passenger side. Any help would be greatly appreciated.

 

I'm certainly not an authority, but I do know that most vehicles have more than one horn tone; it's apparently a safety thing, since some tones aren't audible to certain people. Or something like that. But it is entirely likely that one horn has burned out, which is why it sounds quieter, and like you've lost a "note".

Somewhere on this forum, someone was kind enough to post the service manual. That should help you find the horn units, and then disconnect and test each one separately. Use earplugs.

I don't know about the TL in particular, but on my last car, each OEM horn (there were two) ran about $150, and it was certainly a DYI type of job.

One word of advice...get the right horns. Years ago I replaced the horn on my first car, and cheaped out. The sound it produced was embarrassing.

 

Sounds like the horn has gone bad.

You'll need to remove the bumper to replace the horn(s).

 

Any TL drivers buy Hella horns for replacement?

PeterPort, what did you do to fix your horns?

 

If you want a decent, attention getting, horn at a reasonable price... Check out the .


They're generally advertised for motorcycles. I bought one for my bike and ended up buying another one for another bike, and a third one for my old truck.

Since it's sort of made for a motorcycle, it's got a pretty small profile which makes for a pretty easy install behind the grill or under the hood of a car.

Plus the sound is impressive from such a small package. I like to think I've made more than one oblivious texting housewife poop her luxury SUV seats when I gave them a blast from the horn as they lane-drift while trying to multitask their phone and mocachino right over me.

 

I don't know why but when I started reading the OP's post, I started thinking about the pranksters who install train horns in their cars...........

 

Never replaced a horn on a TL but should be easy enough. Might need to remove the front bumper to replace it. Might have some bolts holding it in place with a connector.

Difficult part would be removing the bumper.

Other then that horns are usually very easy to replace. Also check the connector to make sure no corrosion or anything is on it.
