Not blowing cold air

R12 is not illegal and it is available. You just have to know where to look. I just bought 4 cans at our Lincoln Swap Meet a couple weeks ago for 10.00 a can. I have never seen an old R12 Mopar system that has been converted to R134 work worth a damn! Ask around, there is always some around, garage sales, always swap meets or someone like me that has about 75 lbs.
