Driving along in the LEAF during the weekend, when the car horn began to sound continuously. It's not the most intimidating sound, but when it goes on and on and on, it's very irritating. Just ask the people at the park near where we stopped to investigate the problem. So much for their relaxing Sunday afternoon picnic ...
Nothing obvious on the dash fault lights so we popped the bonnet and started playing around with the fuse box. Took a while, but we finally managed to pull some fuses. Taking out the anti-theft horn fuse (relay?) didn't make any difference. When the fuse (relay?) for the horn was removed, the noise stopped. Relief all around!
My wife was actually quite happy with the incident as the exact same thing happened to her about a year ago. However, in this case, the horn went silent after 10 minutes or so. Nissan did a quick check on the car and couldn't find anything wrong. She's been wondering if the noise was imagined. Definitely not!
When I asked the Nissan dealer for their advice on what caused the problem, they asked me to bring the car in for a full systems check ($150).
Before I spend the dollars, I'm curious to know if anyone else has experienced something similar. Was a full systems check needed to identify/fix the problem? Could it be as simple as replacing the horn fuse (relay)?
