Where does the horn wire connect , from where to where?

you answered your own question a simple fix would be to add a good ground wire to the column. check the wiring that runs up the column to the wheel and make sure all wires are connected and in good condition.

it's sounds that the horn is bad to check to see if horn is bad is to a get voltage meter then take the wire off horn then put red lead in the plug then to body of car then go push the horn , make should put meter where you can se it. If you don't have a meter you can take a wire from the horn where you pulled off the plug if horn don't sound it's the horn

Horn has died or wiring broken.

No way Re attach the ground wire though

First thing check that it is not a blown fuse. Next unplug the horn wire and make sure the horn works by applying battery voltage to it, run a wire from the possitive post of your battery to the terminal that wire was connected to. If it works I would then check that the wire going to it is not damaged. If all looks good then it may be in the horn button itself...this maybe harder to get to and probably not within your ability...

As this is not a necessary part of the safety system I would recommend either finding the horn and unplugging it or remove the fuse.Horn fuses are usually found in underhood "Convenience Center" Should be marked "FUSE BOX" which is located near the battery on most vehicles. A simple call to Autozone or Napa can lead you to the answer as to where the horn(s)

hope this helped at least a little.

most new cars have what is called a clock spring be hind the steering wheel.this is a flat ribbon cable like what you would Se in a computer.what can happen when the ribbon is damaged is the horn can quit working.the cruse control .and the air bag light will come also.but most likely one of the problems will occur.but over time the other problems start happening also.so are you sure you are getting power to the relay .use a volt meter on the terminals under the relay and have someone to push the horn button.this will tell you if you are getting power from the horn button.

First check fuse then relay. If trouble finding obtain repair manual.
Basic diagnostic method is to start at the horn(s). There should be two wires. One is negative the other positive. If connections good. You will need a voltage tester and a jumper lead. A simple 12 volt bulb can be used as a tester. Pull one of the horn wires and attach tester then attach other tester lead to negative. Test horn. If no indication repeat with other horn wire (don't confuse horn connections). If voltage present Horn defective. Next check for voltage at relay. If voltage in to relay but not out replace relay. If no voltage in to relay replace fuse. If still not found then problem is with horn switch or wires between.

as there is an airbag i'd respectfully suggest you have an experience techy work on it.

those things hurt when they pop... not to mention the cost of replacing them

Please take a moment to rate the solution thanks

drivers front behind bumper,you will reach it from under the car not from under the hood!!!! once reinstalled don't forget to set the horn ":pitch"
