We just had 3 days over 100 degree in a roll here in Texas when the compressor starts leaking...

When I first noticed no A/C this morning, I found some A/C oil (green) on my garage floor where my Expedition parked over night. Since that location is right under the compressor, I checked the compressor and found the rear end of it is wet. I took a picture (you can still see the green oil droplets around that area):



Since I never touched the A/C on this truck before, could anybody here tell me if there is a simple fix for this? It may be just some O-rings I hope.

Could anybody tell me how and where the hoses/tubings attached to the compressor on this truck (screw and O-ring size, etc.)? I really need my A/C...

Thanks!
