well, the AC died. works only at highway speeds in mediocre way.
I took it to dealer because cooling system was a nightmare.
dealer says 210 to diagnose. i say ok. i get quote to check it for leaks today at 650. i still think an ac manifold could diagnose it and add some dye to check for leaks.

now to the question: anyone know details on how to diagnose a AC?
i will buy the AC manifold and dye tomorrow after i pick up my little rangy.
