After trying a few times to fix this thing myself, I gave up and took it to a pro. The compressor, condenser, accumulator, orifice, and the line from the condenser to the accumulator were replaced.........after flushing the evaporator and remaining parts. All parts except the line were aftermarket. I don't know if replacing the compressor included the clutch or not. The tech told me he charged with 42 oz of 134A, which is exactly what Ford calls for.Total cost was $1600.
Last Friday, a 100 degree day, after the truck sat in the driveway sun I started it up and drove approx 12 miles The diffuser (vent) temp in the cabin never went below 81 degrees.....unsat. Tuesday a 90 degree day, after sitting in the sun I drove the truck back to the repair shop. The distance was only about 1.5 miles and the vent temp went to 61 degrees!! It this Murphy at work or what?
The shop could find nothing wrong, but replaced a compressor switch anyway. When I picked it up it was about 90 degrees. I drove it about 15 miles and temp never went below 61 degrees. In my other vehicles, after driving a couple of miles in this heat, the AC vent temp is so cold it almost hurts to hold my hand directly on the vent........not so in this truck.
So the truck is still in the shop, but I believe they are scratching their heads about this. The shop has installed plastic caps that must be broken off over the Hi/Low ports to use them......this to insure that system is not tampered with while under warranty.
I would like to hear opinions on just what we/they should be doing/checking at this point.
