I guess I will just have to pull the orifice and take a look see.
If your outlet temp is 35* then the compressor will automatically turn off before freezing your evaporator coil.
Your low high side pressure might be due to the low ambient. There is just no heat to remove from the cabin and the condensor is extremely efficient at 65* ambient.
You might not have any problem at all. Just low temps.
edited= 65 to 35 is only 30* delta drop. The system should be capable of 35* delta at 90* ambient, and 30* ambient at 100*. More if you are humming down the highway. Today your system is just not having to do anything.
