If it was the AC compressor.
Buy Auto Parts on Ebay sells a kit that comes with a New Compressor, New Orafice tube, New Receiver Dryer, and a bottle of PAG oil for $205. I did the whole thing in like an hour and a half.
Beware though. Ford changed the fitting on the receiver. So you must get the new suction discharge hose or it wont fit. That was a $100 unpleasant surprise.
