A/C evaporator

what are your pressure readings?? Roy

Check the blend door operation. This is the little door inside your HVAC unit that guides the air either over the heater core or the evaporator or some of both. Turn your Temp Control from as hot as it goes and then down step by step and the temp should really change. If not, then this could be the issue or 1 of the issues, Fords are really known for this, I have personally done several. I assume that the compressor runs fine and the gauge pressures look good, yes?

i agree. the high side is important. how much freon did you add? was the low side line cold to the touch? Roy

I would go with the orfice tube which is in the liquid line. that is the line from the condenser to the evap. I still dont think you need a evap. Roy
