Hi, I have a 2003 1.4 Fiesta Zetec and on turning on my headlights I get a continual noise coming from them, I believe this may be the motors that have broken in the automatic adjusters. Has anybody had similar trouble? If so what did you do to rectify this? Also if i have to buy new headlight motors do they come as part of the headlight unit or can they be purchased seperatly? any help in this matter would be great. thanks.
