This mourning my parents told me my horn was on. So I went outside cause i though the alarm was going off or something. I use keyless entry to unlock everything but it didnt work. So i went and turn on engine,horn turned off. I let car warm up, turn car off and horn sounded again. I open hood disconnect negative terminal and took off horn fuse and it went off. How can i fix this. Is my alarm trippin so the horn has sounded.

 

probably an electrical short somewhere

 

okay... and how can i fix it. i know has something to do with alarm

 

When this happened to me, it ended up being my BCU fuse being blown. Check that fuse (its in the fuse box right next to the battery). Hope this helps.
