Horn Relay is failing (switch is closing) perhaps due to cold weather. Take relay out and test in freezer to see if switch closes. Or, there is a short somewhere in the circuitry - especially look at the steering wheel horn switch, as that assembly moves and could have been chaffed.
could be either. or a fuse.
It could be the relay or the fuse or the horn itself. Or, it could be all three!
You have to determine the cause first. Check the horn switch and contacts, fuse, relay and the horn itself.
It is in front of the radiator and the horn itself can be bad.
To start with you have to determine the reason the horn has failed. Check the fuse, the horn relay, the horn switch/contacts in the steering wheel and the horn itself. Once you have found the cause then you can fix it.
could be horn relay in underhood fuse box. or bad horn..
An electrical short to ground.
Check to see if you are getting power to the horn itself if so it may be bad Could be horn relay Could be horn switch Replace with an auxilliary switch on dash
It could be the horn relay which is typically located in the fuse box. It could also possibly be a defective horn switch which can be checked at the proper relay pin location. You will need a service manual for the proper pin location. The wiring could be bad. Or it could just be the horn itself.
A loose wire would cause the horn to stop working on your Dodge Avenger 2.4L engine.
See if you are getting power to the horn itself-they have a tendency to fail If not it could be relay or switch at steering wheel
check the horn relay or the horn itself!
