bump -

I purchased a the Haynes 'Heating and A/C' techbook and now this whole AC thing looks much less intimidating.

But they did not describe how to discharge an R134a system.

Could someone enlighten me on how to do it? It cant be hard. I suspect my system has discharged itself already, but to be sure....
