I'm in the process of bringing back to life a 56 Bird that has been sitting for 25 years. Finally got it to start and drive, so I have started on the cleanup process. The issue that I have now is one of the horns will not work. The drivers side works, but the passenger side refuses to make a sound. The wire to the horn shows voltage when the horn button is pressed, so I assume it is a bad body ground or a bad horn. Now the problem is what is the best or only way to get to it? Removing the radiator seems like the easiest way to get to it unless there is a 'secret hidden access hole' that I haven't found. The car has an aftermarket A/C installed and the condenser hoses go through the opening right where you would work normally. Any suggestions?
