Jeep had a nightmare
 

So about 3 am this morning my Jeep horn starts blasting down in the garage...scared the Holy bejesus out of every body in the house(garage is below my house) I had to unhook the batt cable to shut it off.I think it was having a nightmare that it was a Honda Civic or a Hummer maybe...lol,WTH?

Do you got a secruity system on it?

Nope no security....and it wasnt a honk ..honk...honk...it was hooooooooooooooooooooooooooonk...I just now unhooked it at the horn,maybe the horn has water or something in it making the connection,I guess I can just use my finger when somebody cuts me off till i figure it out.

Are u 100% sure it dosent have the secruity bec I thought the same about a jeep I bought and it did the same thing!!

i would be scared to if a had a nightmare that i was a civic or a hummer, mine has fits every now and then too its so weird, its like shes talking to me, every now and then it just honks real quick, when its off too, it happened this morning, and it was hilarious cause my buddy just got done saying that it had a mind of its own haha

No alarm I am sure. I have had this jeep awhile no red lights on the dash or mystery wiring or any thing that an alarm would have, factory or aftermarket...If by some super off chance that it did then it took it 2 years to go off,Only thing I can come up with is this new recovery bumper does not cover the horn itself,and I spayed the under carriage down really good yesterday

I cant see how a horn would go off by its self with water spray . the horn is activated through the steering wheel. I would start looking at that first.

Yeah true,but if the connection at the horn is completed with water in the mechanism it would still blow just a theory,but could be at the wheel I will check that too thanks,and seems like it woulda blew the fuse if was water

Check the horn relay under the hood, it may be going bad or stuck closed...Tj

Thanks Trekerjmm i didnt even know it had a relay

My horn did the same thing one day. I was sitting in traffic and all of a sudden my horn just went off. It just blasted. People were looking at me like I was crazy. I started punching the steering wheel but that didn't work. I eventually was able to pull over and I pulled the plug at the horn. Never got around to fixing it.

Temperature changes cause the air bag cover on the steering wheel to tighten up and depress the horn switch. It always seems to happen at the early morning hours. You can pull the fuse every night, unplug the relay, or replace the air bag. My local self serve boneyard leaves the air bags in the vehicles there, even undeployed air bags. Maybe check your boneyard out and see what they have to offer. Brand new will be costly.

Ha ha that's awsome lol

Not the first time ether. I got out of school one day and as I was walking across the parking lot I heard a horn blowing. I thought it was just some one messing around. As I got closer to my car it got louder. Don't know how long it was going off but my car wouldn't start.
