Horn doesn't work in car but does work with key fob

there may be a problem with wiring in steering column? The horn switch on steering wheel and that wiring circuit is ground for control side of horn relay. The horn relay is not serviceable. If the relay was the problem, you could mount external relay. It just depends on the problem? If the horn sounds at all then I don't think the fuse is the problem. good luck

How to Fix Car Horn

Circuit for the horn button in the steering wheel goes through the clockspring, which also has wiring for the drivers air bag, cruise control operation (if equipped), and radio controls (if equipped). The clockspring unit can be replaced, but BE SURE to disconnect the negative battery cable and wait for an hour before trying to remove it so you don't inadvertently set off the driver's air bag.

it will be in the horn contact /ring/pin under the steering wheel. probably no contact to complete the circuit .

The button on you steering wheel is the problem, try to open it up and pull the spring just a little bit. I think you have used it too much ;)

YOU HAVE TO REPLACE WHOLE AIRBAG AND HORN PAD ASSEMBLY BOTH BUILT INTO ONE.

If it is the same horn, there is probably something in the area where you push to activate the horn. The horn itself is obviously working so there is no fuse problems, most likely your problem is in the steering wheel.

Try unlocking the the door with the key and then lock and then unlock again the may disable the security system

Horn problem is either bad horns or failed clockspring behind steering wheel which is the connection for the airbag and horn buttons.

there are two seperate horns
