What to check if the horn doesn't work in my 2007 Chrysler minivan?

Answer 1

Start by checking the fuse panel for a blown horn fuse in the fusebox. If it is good, move on to the horn button and relay. The easy way to see if these are working properly, turn the key to "on." There is a horn relay, probably in the fuse box. Push the horn button and listen to the relay for a "clicking" sound. If there is a clicking sound when you push the button, these two should be ok. This should narrow the problem down to the horn itself. I have owned two Dodge vehicles and have had to replace a horn on each of them and this was how I determined that it was the horn and not other circuitry.
