Hey guys a strange thing happened today. I was driving when all of a sudden my horn went off for about 10 secs. It stopped then then a couple mins later off it went again but it wouldnt stop. I pulled over and removed the fuse. I swapped out similar relays and got new horns but still the same problem. Have any of you guys experienced this? Any suggestions as to the problem.

If you are in the habit of hitting the air bag with the palm or your hand or punching the air bag, then the horn contact/s on the steering wheel, under the air bag, are broken.

Thanks 43sqd, I will give it a look tommorow.
Are you in the habit of striking the air bag to sound the horn?

Remember to disconnect the neg. battery cable for a couple of minutes before you remove the air bag.

Thanks again 43sqd. You were right the rubber washer from one of the screws was missing. I dont usually strike the air bag but I do use that side most of the time when pressing my horn. I have uploaded some pics just incase others have the same problem they know what to look for. Thanks again.
