Cadillac Repair: 1988 Cad. Eldorado, 134 freon, r12

Question
I live in Yakima Wash. and never heard of the auto parts store you mentioned in your response to the question of how to change from R12 to 134a? I need to change over and need direction and advice. thank you.

Answer
I can give you all the information to convert the system over to the 134 freon. However, the sensors are are NOT calibrated for this type of freon and some conversions run into problems with turning ON the check engine light.
