If you expand the guitar variable, you might see what's going on:

\score {
  <<
    \new ChordNames {
      \set chordChanges = ##t
      \new ChordNames \chordmode {
        f2 c |
        f1 |
      }
    }

    \new Staff \context Voice = mel {
      \melody
    }
  >>
}

The second '\new ChordNames' will create a _new_ ChordNames context. The \set 
chordChanges=##t command will only be effective in the context from the 
_first_ \new ChordNames (which will contain no notes).
