Next time your Auto breaks down, Call Ford and ask how to fix it. Or call the local Ford or Repair shop and ask how to fix it. What do you think they will tell you? They are IN THE BUSINESS to make money repairing Autos and not in the business to tell YOU how to repair your auto. SAME with RV supply companies and RV service centers. I get calls from people like you weekly and all I tell them is, make an appt to get it in and we will fix it for you at a reasonable charge. Then THEY get upset. Some people have no clue how other people make money. Doug
