Message	Hello folks, It seems the day has finally come where the A/C system on my 93 300ZXTT is giving up the ghost. Its blowing warm even when cranked to the cold setting. I'm assuming this means I have no or low refrigerant. I haven't attempted any other diagnosis yet. Assuming it is the refrigerant, what are my options? Even a local Nissan Master Tech some of us know here didn't seem to have a go-to path when asked. Thanks. * I am in Canada, and I intend to retain a working A/C system. Inzane
