This is why air conditioning work should not be left to do-it-yourselfers. Hi, Docfixit, would you agree? At school the kids are required to wear safety glasses all the time in the shop, AND face shields when working with refrigerant. How many do-it-yourselfers know that escaping refrigerant can freeze eyeballs and cause frostbite?
I couldn't believe that someone told this uninformed person to charge through the high side unless he was hoping to cause problems. Why would you want to pump high pressure back into the can instead of suck it out of the can on the low pressure side?
El mike, you were misinformed by your mechanic, you don't understand how these systems work, and I'm betting you don't know the necessary safety precautions. I never like to discourage people from learning more about cars and working on them when they feel competent, but for your own safety, this one's best left to the professionals. Maybe you can find someone in a smaller shop who will let you watch, but it's not worth going through the rest of your life blind.
By the way, did you notice that the high and low-side ports are different sizes? You can't put the charging hose on the high side; it won't fit.
