Ok, I'll give a different perspective to this problem. If you have a legitimate concern that the repair was not correctly done, you need to report it to the service manager of the dealership. I dont mean "*****, whine, moan, piss, complain, etc" Be professional and BE FIRM. Have documentation. Be in control. Save the ranting and raving for another occassion. DO NOT ACCUSE. Be an ace and you will be treated with respect. If one of his employees clearly blew the diagnosis and repair, it is in the best interest of the service manager to know. This is the ONLY WAY that the responsible tech is going to LEARN and PROPERLY REPRESENT FORD - the company that he works for. To NOT do anything is to let this kind of incompetance continue. FORD needs to MAKE IT RIGHT. I know this may be idealistic, but there is no other way folks.
NO ACTION = CONTINUED INCOMPETANCE.
My idealistic two cents ...
Good Luck,
