Earlier Focus had problems with it, due to somehow broken door/mirror seals.
Mine (1999) has this annoying problem, there is a notice from Ford how to
solve the problem, if you have some warranty, Ford will pay. I haven't and
didn't liked to waste the money until now, so I just turn up the sound, glad
to have a good audio system. The questions is, when was your Focus built?
