hi there just wondered if anyone has the same problem,just inherited my wifes fiesta 1.4 2004 and this has happened since 2006 but she never goes that fast! now i have the car it does my head in after 70 mph near 75mph terrible whining/squelling sound comes sounds like from the central blowers any help to get rid of this would be much appreciated by the way the faster you go after 75 the louder it gets.
