horn fix/adjustment
Background - skip to 2nd paragraph if you are in a hurry:
The horn(s) on my 2006 SV8 had never worked since we bought the car and I removed them while I had the bumper cover off to see what the problem was. There was 12V to the horn connector when the horn button was pushed, but neither horn worked with 12V applied directly to individual horn contacts. Also, the left inner fender (wing) liner is missing part of the bottom front and both horns had water inside them. I had shaken out as much water as I could and had actually used more fresh warer to try to wash mud from the inside and I let them dry several days until I could hear no more water inside and tried them again on an external 12V supply. One horn "clicked" and had some continuity and the other did nothing and had no continuity. I figured they were toast and was looking for some cheap (spelled free) replacements from my bro-in-law's car scraping business. I drove over there yesterday to take horns off a Jeep Cherokee he had because OEM replacements for the Jeep on line looked like they had the same connectors as the Jag horns, but unfortunately someone had replaced the Jeep's OEM horns with little Italian air horns and a little electric air pump that didn't work either.
So......Today I pried the little rubber nubbin off the back of the horn that did nothing, found an adjustment screw under the glued on hard rubber cover, turned the screw a little counter clockwise with vice grips, and applying 12V got a "click". Turning it farther I got "click/rasp" and turning farther yet I got an actual "honk". I then took the horn that had "clicked" and without removing the rubber nubbin just turned it counterclock wise maybe a 1/4 turn with vice grips and got a "honk" out of it too. Putting the wiring pigtail back on both horns and applying 12V to the two pin connector I got a loud two tone "HONK". Whoopie! Now I can reinstall the horns (bells down this time) and put the front bumper cover back on (after testing the horns again in the car, of course).
Even a blind hog finds an acorn now and then.
