Hi my a/c light keeps coming on in my 1992 Cadillac Deville. It says refrigerant is low. It comes up with an F48 code. It has R12 refrigerant in it. I have a 30LB tank of r12. My question is what is the low side pressure suppose to be at and what does the high sides need to run also. Thanks.
have the same problem?
