Can a 1991 deville with climate control be converted from r12 to 134a. i converted one after installing a new compressor,orfice,accumulator and flushing system. i can,t get the f12 code (ac temp. switch lowside error) to clear. if it can be converted how much 134a will it hold nd where is this temp. sensor located that the f12 code is talking about.
