My 2008 Expedition had a hole rubbed in the A/C line to the rear. I'm not sure exactly where. Ford was going to charge almost $500. I went to local mechanic and for just under $175 (I think that is what is was) the line was repaired. How he did it I was told was to splice the line where all Ford would do was install a complete factory line. Easy Peasey repair the mechanic said.
