Ok, sorry to hear that.

I've had success twice with a 500g charge. Does the compressor still cycle with a lowish charge? If I understand correctly it should not do this.

Does anyone know if all SVX A/C systems are equal (not counting the juice)?

Mine never cycles and this is how it is supposed to operate... the cooling is controlled by the variable displacement feature in the compressor and it should be cut off only as a protection feature for too low or high pressure and if the controller thinks the evaporator is realy freezing.

I think a dealer can read the evaporator temperature with the diagnostics kit... maybe the thermocouple is bad? Are you sure your compressor and pressure switch are really OK?

If all that checks out next thing I'd do is replace the expansion valve. Sticking should be readily picked up by a professional from the pressures, though.

Sorry for not being able to really help.
