Do you have good ears?By that I mean, can you hear a chord and in your head be able to isolate the individual strings that give the chord its tonality?
If so, then try isolating all the notes that make up the chord(s) and find them on the instrument. Doesn't matter where as long as they're the right notes. Once you have those notes, then experiment up and down the neck and group them in the closest cluster that is easiest to play.
