Horn wont honk

lindjung · 02-19-2009, 12:58 PM

so the horn on my 300 just stopped working, its not the fuse, i checked that, the horn will honk when i lock the car or press the panic button, but it wont honk when i push the steering wheel, what could this be?

then its gotta be the contact in the steering wheel,now I havent pulled a"C" wheel but most wheels have a large plastic ring that activates the airbag and the contacts for the horn is in that same ring that activates the airbag,could be a break in the wiring somewhere though.I hope I'm wrong though

Because the horn sounds when you press the lock or panic buttons the trouble is not the horn relay, power to the relay, or power from the relay to the horns. Something is having a problem between the horn button in the steering wheel (certainly not the most sensitive to start with!) and the front control (FCM) module.
Are any of these diagnostic trouble codes in the EVIC: B2336, B2337, or B2338?
If you would like I can scan the HORN section of the service amnual and e-mail it to you. It's like (12) pages and has step-by-step instructions, including schematics and diagrams.

The horn is finicky. You have to press the right spot and usually with a lot of force. Try hitting different different spots with a lot of force.

it won't work if the ignition is turned off BTW,

also being you have a 2005 depending on your build date, you may have the problem where the steering connector is too short and the horn connection has pulled away from the connector..

there is a TSB and repair kit out there to extend the wire loom 6 inches to resolve the issue..

Section "8H - HORN" of the manual sent via e-mail.

While it sure would be nice to know if any trouble codes were set so as to follow the steps of the troubleshooting procedures, after reading through those procedures it looks like a test light and voltmeter are all that are used.

As the control of the horn relay appears to originate from the front control module (FCM) you might also be poking around at the wires and connectors up underneath the front power distribution center and the back of the FCM for a loose connection.
