One thing I've never tried to mess with myself is A/C. The mechanic who recently checked out my non-functional system said the compressor was ruined because a previous owner had converted it from R12 to R134. This didn't surprise me, based on what I've read on these forums, but what did was his categorical remark that replacing it with a used or rebuilt compressor wouldn't do. That struck me as unrealistic and perhaps also just mistaken. Can anyone with experience with used or rebuilt compressors confirm or deny whether these are a viable option on old Mercedes? Are there any details I should pay particular attention to when looking for one?
