Hello I have a US Spec 1993 SE and the A/c is not running cold at all. I have been told that the A/C unit in mine takes R12 which I have been told is very very expensive. My questions is the following: I read on one of the web sites about using Freeze 12 as an alternative to the R12 fluid. I read up on the U.S EPA site that states Freeze 12 is a good option to R12. Has anyone used this product before or does someone have a different option for recharge?
