Horn problemma

My horn stopped working a few weeks ago. I cannot tell you how many times I've needed it (more than any other vehicle ever!) Since we don't stop or dodge so fast, a horn is as important as my brakes.

Where do I start to figure out the problem? Worked one day and then it didn't the next. Photo, please, Don if you have one.

12 V direct to the horn contact (actual horn!!) do it work>????

The problem is either the horn itself, or the circuit sending power to the horn.

I just went through this on my '65. I gathered up all my spare horns from the parts vans I had and tested them all on a new battery. Only two horns out of 6 that I had were good. The rest were junk and did not make any noise, so they went in the trash.

The horn must make a good ground to the frame. With the horn off the vehicle, make sure the bracket is ground to bare metal, and hold that to the negative terminal of your battery. Connect a jumper wire from the horn contact to the positive side of the battery. It should sound. If there is no sound, the horn is junk. Hit the junkyard for another one.

If it does make sound, re-install it on your van and then you know the problem is in the switch, relay or wiring and you can start troubleshooting the electrical circuit.
