Mazda Protege 1992 DX
All, I'm contemplating taking my ancient 141K Protege DX back to Tucson AZ. Problem: AC not cooling. I'll diagnose the problem to ensure not compressor, but has anyone had recent experience converting their 90's era Mazda from R12 to modern R134a? My vehicle has other issues so I don't want to sink many more $ into it. Thanks for reading

If anyone else is in the same situation, the stock AC compressor on 1.8l engine was fine after straightforward conversion to 134A. Car cools well, so off to its slow death in S. Arizona soon.
