I have a few of the (small) DIY cans of R-12 left over and was thinking I would try to get the A/C working. I bought the car almost two years ago, and the A/C has never worked. Anyhow, the Drier/Accumulator has two LP connectors (one is the old Schrader valve and a quick-connect valve) The quick-connect valve looks like a R-134a connection. No stickers on the compressor, or under the decklid or under the hood. Is there any "easy" way to tell if it has been converted?
