Did I ever mention that my uncle had a truck much like yours, I think it was an
'01 and had MASSIVE electrical faults with it? His liked to cut out
periodically, it'd sit dead for 1-20 minutes and then randomly would drive fine
for 1-180 days. It got so bad that the Ford dealer finally gave him a nice deal
on a newer truck. I think his newer one is an '05 or '06 and he's had almost no
issues with it.
I suspect if you traced around enough you'll find that the horn button in the
wheel goes to some kind of computer controls and thence to the horn. I'd also
suspect that the computer has gone somewhat wonky...

Yesterday morning I was working in the garage on my wife's car when a horn
started blowing. I went looking to see
what was up and learned that it was my truck. No idea why it was blowing but it
would not stop. I pulled the
battery cable and let it sit. I need now to find out what is up. My first
thought is that a wire has rubbed against
something and shorted to ground. Going to check down under the bumper where the
horns are if I recall to start
with. Don't think it should hurt if I just pull the wires from the horns and
drive it if I can't immediately solve
the problem.
Anyone with good ideas on what or where to look if it is not immediately
apparent what is wrong?
Its a 2002 Ford F150 Supercrew 4X4 with a 5.4 so nothing too fancy or elaborate.
