anyone know where i can find one online. or would the r134 be just as cold as r12 with a compressor for R134.my air doesnt work right now.it started acting funny one day.worked great untill it got like 90 degress out then it would quit working.when it cooled down outside it would work. now the compressor just kicks on and off. if im going to get it serviced i would like to have a chrome compressor to go with it.i would like to stick with r12 if possible because i like it freezing.
