Fuses

[buddyguy]

I have posted my non working horn problem but I have this strange. Thing occuring where my horn won't work by pressing it but it will come on by itself and will stay on i have even removed the horn fuse and it will stay on. Did not pull relay but just the fuse and that would not shut it up. How could it stay on when I pulled the fuse? Why would it not need the fuse to complete the circuit to get it to sound?

There must be a short directly to the horn that is bypassing the fused wiring system.

Did you check for codes -
Do you have a key fob panic mode?

2000 Plymouth grand Voyager. 3.3. the answer would be no on your questions

Did you try the key on off trick? It should flash a code if the body control is shorted, but I suspect as Jackc said, short direct,

Of note, since now we know there is a short directly there, plz be careful when working on that airbag system live. You could get surprised.

Buddyguy,
This is the same vehicle with the airbag clockspring issue isn't it? I ran into a strange horn related problem with a Jeep (also a Chrysler product).. You get a chance, read this:
