I would check and see if it has a blowed fuse first.
yes horn is not working
check the horn relay or the horn itself!
Fixing the horn on this car will depend on what cause it to no longer work. The fuse may need to be replaced, the wiring, or it may be the clock spring.Ê
The most likely common cause is a failed clockspring in the steering column.
A loose wire would cause the horn to stop working on your Dodge Avenger 2.4L engine.
clock spring
clock spring
could be horn relay in underhood fuse box. or bad horn..
in the fuse box under the hood it will be listed on the fusebox cover to witch slot it falls under.
bad ground or wiring, bad switch/button, bad horn, bad horn relay, fuse.
I've got the same car, and my horn isn't working, it works sometimes but rarely\ If its has Airbags , you should check the Spiral Cable , you have to remove the steering wheel
Check the actual horn. Clean the contact points and apply dielectric grease to the contact points. Test the horn for resistance. Check the horn relay.
