The car horns are the two behind the front bumper.

The alarm horn is under the front hood near the battery.

I knew of at least two from reading posts! Found the third now thanks.

Put 12v on the connector with the horn removed. Interestingly there is always 9v present to the connection, sound right?

When I trigger the alarm is does spike to 12+v in unison with the lights so we are getting correct voltage to the horn. Therefor I pulled the horn and hooked it up to a 12v Motorcycle battery and no sound. so there is my problem.

Why 9v all the time to the horn?

Is this the same horn as below with the other two that are so prone to fail?

Wonder why the failure other then low quality, lack of use?

Let me add this questions:

Should the horn "chirp" when arming or disarming the car or just the lights flash?

Is two for on and one for off, correct? Manual states two flashes signals an error and I do have a "internal sensor" error that Loren has stated is a very common error that often doesn't affect the alarm from working.

When the system is properly armed the lights should flash twice -- no horn. A horn chirp means one or zones is open (and not armed).

Common causes of an open zone are the armrest cover and the front trunk microswitch.

Is two for on and one for off, correct?
Two flashes to arm is normal and one to disarm (at least my car has always done that and I have no alarm fault codes).

Thanks. What do you think about that 9v present all the time to the horn?
