Sweet my friend that's awesome that it was that simple for you to get things up and working.
My system when I hit the AC on my dual climate does zilch, zero, nada, nothing. Hear no compressor kick on feel nothing but superheated air! There's many shops that will do such a thing to you and there's many people that say do this do that, blah blah blah! However the way things work for me and working on cars I'll buy two cans fill it up and it all leak out or it will do absolutely nothing.
I guess I should get a couple cans and try, worth a shot.... to be continued!
