If the lines froze up its low on refrigerant or the Ester oil was not added
Also did you add some Ester oil which is compatible with Residues of R12 as well as the R12 oil?
As well was was the total system requirement for R12?
Usually you add 8oz of ester oil then, you take the amount of R12 required for the system and devide that by 85% and that what you will need of the R134
I have done this to 2 cars and both still have the original compressors and still cool me down on a 90F day...
I am supprised that my 91 Bonnie has given me almost 16 years of cool air in the summer and the H6 Compressor is still not dead... I changed to R134 over 6 years ago
