Hi, Bought my daughter a three year old Fiesta SE (2011) when she graduated from college - to make sure she had the means of leaving the nest! Recently she called to say that her headlights did not always turn on when she turns them on - this car does not have Daylight Running Lights - she has to turn a switch on the dash. I traded her cars and experienced the same thing - 99% of the time the headlights come on - but occasionally they do not. The brights worked. The various other amber lights all worked - but not the headlights. I don't know what to change to fix this. Seems like it cannot be a fuse or it wouldn't work 99% of the time. Same with Bulbs. Wondered about the actual switch itself - but it seems unlikely. What else might make this happen occasionally? Thanks for any insights. People at various AutoZones, O"Reilly's, etc did not seem to know - in fact, one of them suggested this forum.
