There's no sound from my horn anymore... checked fuse, checked connection by the horn itself. Nothing seems wrong. Anything else to check?

 

Voltage to the horn.

Have someone hold down the horn button (or set off the alarm or panic) and try to measure voltage to the horn.

If you see voltage then your horn is toast, if you don't it is time to visit the stealership. If you do see voltage then it is time to upgrade to a better horn.

 

Good idea!

Actually, now I remember that the horn honked loudly a while ago, when putting back the cables to the battery after some welding...

 

There are 2 fuses for the horn. 21 and 23. Check em.

Also there is a relay in the fuse box. If you set of your panic button you should here it clicking. If you dont then you know it maybe be a bigger problem.

 

Ok, tested to measure voltage during pressing the horn at the wheel, no juice.
Checked both fuses, they're ok.
Do you know which relay it is? (Number?) Panic button? Where's that?

 

On the key FOB

 

Have manual locks...

 

I'm pretty sure that the two fuses in question are 22 and 23.

I just replaced my stock horn with a air horn and found that these two fuses were identified for the horn. When I pulled either one of them the horn stopped working.

Double check the list of fuses on the under side of the fuse panel.

 

You're correct. Those are the numbers. And - they're ok... Ok, guess the dealer has to look into it...

 

This is a great thing!

You can "lay on the horn", and not wake the neighbors!!!
