I had this Dixie Horn for about 5 years and it finally quit working. The air compressor would run, but not sequence properly and 2 of the horns would no longer make any sounds. I used this horn in my 1993 Chevy van and my 1971 Dodge Demon. As soon as I bought my Metro, I installed it, but removed it when I discovered it was broke.
I am not one to let a $60.00 horn go in the trashcan, so I modified the horn so it would at least be use-able. I removed the top cover and removed the rotation diaphragm and springs and then used silicone to seal the horn and also block off all of the ports but one................
I then let the silicone dry and used the longest (loudest) horn and hooked it to the single port. I now have a very loud single tone air horn in my Metro to replace the cheezy horn it has. It sounds like a big rig horn.............
