Question about Cadillac DeVille
Look on the AC compressor there should be 2 lines coming out. The low side is usually larger in diameter, not always they can be the same in diameter. Sometimes the low side has a blue cap. If the compressor is still working and you are just topping the system off, the high side will be HOT to the touch. It will burn you after it has been operating a while. The low side also comes from your filter/dryer. Your high side general runs straight to your condenser (thats the heat exchanger thats usually near the radiator. I hope this helps.
