I let me friend borrow my jeep and now every timeout touch the brake pedal the horn sounds!
It's impossible to drive without attracting attention!!
Do you think it could be a fuse or a bad horn?

 

lol That's pretty funny.

Unplug the horn for now so you can drive it. It sounds like you've been had.

 

All you do is run an extra wire (I believe copper) from the horn to the brake

 

From the horn to the brake?

 

bimmer is that you?

 

Your friend is obviously an *******. I'd start with disconnecting the brake light switch to see if that helps. (Obviously just to test, don't drive around like that...)

 

Winner!! One of the oldest pranks around. Open the hood and look for a wire going to your horn. Other end should be connected to your brake light switch. Hell they even put this one in JP magazine.

 

You think he's pranking me? I was watching tv when I heard a horn blaring while pulling in my driveway. He said he didn't know what was up with it and suggested I bring it to a shop or have autozone scan it.
I looked under the hood and found wires but I don't know what they go to. I crawled around underneath trying to find the horn and it was under the bumper. I could not get the plugs off so I cut them with scissors.
I can drive it now but I need my horn! I gotta get this fixed!!!

 

Problem solved.

 

Yep, he got ya.

 

Yeah he pranked you and made it sound like it just happened on its own.Only way for it to happen is like said someone wired the horn to the brake switch.

 

Now it is possible someone pranked him. Just happened to be in your jeep.

 

You need to put some fish under his drivers seat
