Cammicopp, welcome to the forum. I hope you will like it here
girl, don't I know what you are talking about. It seems that if repair shops see someone not understanding in a certain subject that is the sign to take advantage of them, because else they 'shouldn't have been so stupid' ( not mentioning one almost needs a college degree only trying to understand how one's car works at all

).
What I suggest you to do is to contact a CERTIFIED Ford dealer - and present to him the case. He wouldn't be allowed to charge you more or cheat you into costs that aren't necessary. If he does so anyway, you contact Ford and tell this dealer about it.
Let me know how you get on
