Thanks for the responses. I took it to a local Auto Zone and the manager said that I was out of freon. He suggested that I get it converted over to the new R?? something or another. He also said that he could do the conversion for me for $200.OO which also consisted of pumping out the old stuff stuck in the system. He is the store manager and he says he has converted over 30 toyotas already. Should I trust him or should I go find a place that will fill it back up with freon??
