the horn sounded like one was not sounding, one dealer charged me for a new
horn and labor to r & r the bumper, when I picked up the car, there was no
improvement. they said tough sh!t, it's an old car and had an accident
before I bought it.  I should have insisted on getting the old horn back.
The serice manager defended his service writers and mechanic.  One service
writer even had the nerve to laugh at me on the phone.  this was the third
strike at that dealer.  I don't know if I should complain to Honda of
America or just let it go.

I took it to another dealer that is larger and has a better reputation, and
was nice enough to give me a ride to work.  Odly the horn worked every time
they tested it and even worked after I picked it up, until 10pm tonight.
now it is back to same problem.  what is a common cause?
