Have a 04 e350 diesel,the air con compressor goes and sends metal threw the system.Ford in N.C wants 2700 dollars to replace system,i have a mechanic that could cut the labor in half or so,trouble is i don't know of anyone that makes aftermarket stuff for ford air systems.Looking for some links and person experience with products if anyone has info.Thanks in advance,left laptop at home so may be awhile til i get back here.
