I have a general question and hope someone can offer some advise. My horn button only will test on the top and bottom of the right side. The left side might test. If I remove the horn button the horn contact will test all the way around. Any suggestions are greatly appreciated.
Hi Craig, my horn button did the same on my 64, what happens is the part that the button snaps into gets crushed back and the button won't travel enough to make the contacts hit. My fix was to put small lock washers between the screws and the retainer center to move the horn button slightly out so the contact will hit before the button for all positions to 'toot'. In other words, space out the center retainer to give more movement to the horn button. Enjoy!

Your problem might be in the horn button/switch itself, rust. From memory, you will need to take the three screws out to remove the button/switch. It is a two piece construction, held together by three plastic plugs - also two piece. I marked the two pieces so that I could put them back together again as they came apart but I'm not sure if you need to. CAREFULLY push the centers back out of these plastic plugs. Now remove the plastic plug. The horn button/switch will come apart. There is a cork(?) insulator witch also must be carefully removed. Now you can get to the rust. Go to town on this until it is all shinny again, coat with electrical contact lube to prevent the rust re-appearing and reverse the steps to re-assemble.
Two of the three metal pieces of the horn contact assembly are identified/indexed for correct orientation to each other (so the folks who made it could put it together correctly). The center part with the three ears for the screws has a radial index line adjacent to one of the rivet holes; that line is aligned with a V-shaped indentation in the center leg of one of the three groups of spring legs on the spring steel cap retainer piece. The round steel piece with the contact "leg" that goes against the steering wheel hub is then oriented with the contact "leg" at ten o'clock when the index line on the center part with the screw holes is at 12 o'clock.
