Want this question answered?
The horn is either damage or the ground wire going to the horn is grounding out on metal or another ground wire. Trace the ground wire. The horn contacks within your horn pad might be grounding out also.
AnswerI had this problem on my '98 Plymouth Breeze. You can pull the fuse/relay and it will stop the horn but the problem is a short located on the airbag/horn button on the steering column. The airbag has plastic washers that wear out over time and allows the short to occur. The fix is to disconnect the battery, pull the airbag off and replace the plastic washers. BE VERY CAREFUL SINCE AN AIRBAG IS LIKE A MINI EXPLOSIVE DEVICE.
why my horn stop blowing
Most likely a short between the horn relay and the horn switch in the steering wheel.
Perhaps a vacuum leak
You can not prevent a sensor from failing.
The horn relay may be faulty. Try replacing that.
There are sever possibilities to the horn not blowing consistently. The horn relay or horn button are the most common followed by a loose wiring connection or a defective horn.
