Got a new actuator from NAPA and it seems to be working, but it was past where it was supposed to be in the heat position, so I had to move it before I installed it. Got the compressor seals replaced and the high side valve was leaking air when I removed the cap, so I replaced that, too. I did notice some dye on the compressor towards the middle on the bottom, so hopefully I don't need a new compressor, too. Everything seems to be working correctly now, at least. I could not find the special function on the Tech 2 to force calibration; must not be new enough for that.
