My horn does not work. I took it off, cleaned everything, found a break in the line and fixed it. I suspect that the pump is not activating. Where is the air pump unit located that provides the air pressure to the horn and how do you access it? Thanks.
You'll have to follow the air line to find the compressor. If you do, put a few drops of oil into the end after removing the air hose, replace and test.
