Horn stopped working... but only when I arm the alarm?

[jplumlee]

Up until last Friday when my car had the coolant pipes fixed, my horn always chirped when I armed the alarm. Now for some reason it has spontaneously stopped. The horn still works so it's not a fuse or something like that. I had a thought that it might be like my 03 Maxima, you could hold the FOB button down for 10 secs or something like that and it would change "modes" and only the lights would flash upon arming? Does the P!g have something like that as well?

Also, is it just me or is the FOB a POS? half the time it doesn't work until the 3rd or 4th try or it will just lock over and over when you press the button. I almost can't unlock the back doors and hatch with the FOB. The other thing it does occasionally is it'll unlock, then about 15 seconds later the alarm will go off. that's really nice. I thought it might be battery related but that ain't it :D

on the other hand... it's nice knowing that the coolant pipes aren't going to explode and leave me stranded.

The vehicle horn and the alarm horn are two separate horns.

The car should be checked using the Durametric Software or a PIWIS tester.

Ok... didn't know that so thanks. Since I'm over an hour away from a dealer, is there a fuse, connection, or way to test the "2nd" horn before going through the trouble of taking it back to the dealer?

thanks!

Just to clarify technically the Cayenne has 4 horns.

There is the alarm (signal) horn.

There is a backup horn (if activated).

There are two vehicle warning horns - high and low pitch. Operated from the steering wheel.

The vehicle horns are cheap horns and are know to be a failure item.

Check the left fuse panel F53 and F33.

OK, so I checked the fuses listed below and they look fine. Anything else I can check before a trip to the dealer?

BTW there was a fuse in that same panel that was BARELY in... I'm talking hanging by the "proverbial thread" but alas no change.

If you have a multi-meter you can always try you confirm the voltage at the horns.

My bet is that both horns are bad.

man I feel dumb... but that's ok, it's cheap! The settings had somehow defaulted to not sound the horn. Not sure why or how but at this point, I don't really care, it's working fine now. thanks for all the help!

glad that solved it -- thanks for telling us. i've had similar issues that were tied to setting changes and i was embarrassed because i was sure bigger problems existed. the mirror settings, etc.
