134A conversion

I have a 1986 Dodge Ramcharger 318 truck and the air conditioner was changed to 134A and it want hold a charge. A dye test was done and it didn't show anything. What could it be?

It is likely that whoever converted the system did not do it correctly. A conversion of this type requires that the seals be changed and that the compressor be removed to change the oil to PAG type and replace the shaft seal. The hoses may also have to be changed depending on MFR's recommendation. If someone did all this, a leak check before installing refrigerant is standard practice.
