Hello. This vehicle originally may have been equipped with R-12 refrigerant and has been converted to R-134A refrigerant. If this is the case, the system will leak out the R-134A over time out of the seals, hoses, and compressor since they were not designed to hold the newer refrigerant. Have the system checked to see if it is low on refrigerant and top off the system using the proper gauges in order to get the pressures correct without over or under charging it. You might even have some approved dye added so the leak can be identified.
