I have an 05 f-150 sc. the horn started blarring while I was going down the road. I have replaced them with after market horns. I hit a bump in the road and they went off. I unplugged one of them and this worked for a while. I was leaving work the other day and the horn was blarring agian. Any suggestions.

 

almost sounds like a bad clock spring

do you have cruise control ? if so do the buttons work on the steering wheel ?

 

Yes, all the buttons on the steering wheel work.

 

well i don't think it would be a clock spring b/c nothing would work on the steering wheel ...in less its just starting to go bad ...more likey a wire problem some where

 

I use to hear a relay behind the glove box clicking now I don't hear it any more. They don't show a relay in the fuse box for it.
