Years ago most cars especially compact came without A/C, dealer installed A/C was common on a lot of these cars. Also the York compressor is a tip off that is was install either by the dealer or places like Sears,Montgomery Ward, JC Pennys etc. Fortunately York compressors are easy to come by if yours is bad. That and the expansion valve are the most common to go bad on these systems. You should replace the dryer while it is apart.
