Horn problem

[Jmaneval]

2015 Jetta TDI SE horn quit working a few weeks ago.. Not sure which fuse to check but checked them all and they're good. Also not sure which relay to check or how to test them.. Horn works with the lock button on the remote but not when you push the steering wheel. Any experience with this?

If you're still under warranty take it to the dealer.

The only way to DIY trouble shoot the fuses is one by one. Unfortunately volkswagen didn't mark the fuse boxes with what the fuses do.

I installed a 2 horn Kit from AA Rodriquez in my 2015 Jetta SEL TDI it actually sounds like a real car horn now....

Yeah the fuses are fine and its out of warranty (53,000 miles). I guess I'm just going to have to bite the bullet and take it in. It has me stumped.

I was just looking at the horn upgrade tutorial and it shows the horn behind the bumper cover.. I found one in the cowl under the windshield (it beeps when you press the lock button on the remote). Is there another horn behind the bumper or did they move it in '15?

Hmm could be a simple loose connection, check the terminal also the horn button.

Horn failures are common. 95% likely hood the horn itself needs to be replaced. That said, key on, push horn button (driver airbag) and listen for relay in dash to click. If it clicks then almost certainly needs a horn.

That's what I was going to suggest, easy to do too.

I also installed dual horns. Great upgrade.

+1 to this, a whole different car, doesn't make me embarrassed to hit the horn.

Seems to me the simple diagnostic is to disconnect the wires from the horn and place a meter on them and press the horn button.

I have the horn that came out of the car if need one

Thanks for the replies everyone. I took the horn out and wired it to direct power, no result. Put a voltmeter in the plug and got 12 volts with steering wheel pressed. So I guess it's the horn.. Ordered dual horn from aarodriguez should have it in a few days.. Meanwhile it passed inspection with no horn (guess they didn't check it). Thanks again.

I've passed inspection with headlights out AND the bulb out light lit on the dashboard... Makes me feel warm and fuzzy.

My horn quit as well.....

Jmaneval, let me know how you like the new horn and how installation goes....I'm guessing you ordered it as a 2006+ and requested the adaptor to support dual horns?

Best money I have spent on my Car!!

Dual horn is definitely an upgrade. It wasn't even worth the trip to the dealer to have my defective horn replaced under warranty.

 

[Jmaneval]

Installed the dual horn today. Installation was simple and straightforward except the holes in the plate that was included were too small for the studs on the new horns. Easy fix though as I just reamed them out with a bigger bit (21/64). Also the included adapter wiring harness fell apart at the shrink wrap when I tried to connect it. I just reconnected it with butt connectors and electrical tape. Sounds good though, big difference from the factory horn.

Where is the horn located on a 2015 Jetta TDI with fog lights.
Is it still located passenger side and behind the fog light, or somewhere else because of the fog?
New horn here at VW is 130.00 buck which is crazy.

 

[tomo366]

Yes it is
