I have a 2002 Ford F-150 Super Crew. I am sure this problem is probably something simple, but I wanted to check before I start pulling relays, fuses, etc. Last year, while duck hunting, my horn got full of mud. I got it all cleaned out, but since then the horn was sounding like a sick cow. It continued to do that until about a month ago, when it blew one last time, and no longer works. I had blamed it on the horn, but a friend of mine made the comment that it might be a bad connection. Anyone have any idea about what could have happened? I am about to start working on it, but thought I would check for any advice first. After reading some of the other posts, I went back and checked further. When I push the horn, I can hear clicking in the power distribution box. I went ahead and pulled the fuse anyway, and it appearred to be okay. I then disconnected the horn and put a test light on the connector. Nothing lit up. I peeled back the insulation on the wiring a few inches back and still no power. Can anyone tell me where the wiring goes into the distribution box? I don't want to try to trace that wire back because it looks like a nightmare in all the wiring. Plus I don't want to electrocute myself nor burn up my truck!!!Appreciate it.
