I kept needing more and more freon air conditioning ac. My car overheated and we put in a new radiator, it was old. It had gook and sludge and blown out aluminum coils. Eight months later the car was over heating, losing tranismition oil. We put in a new radiator since it was under warranty. Now, I had an ac test done and was told that it failed the vacuum and blow air test and I think the die leak test. But I was looking at a new blower, a condenser, seals and a lot of labor. . The real trouble can be oil from the transmission, engine, and air conditioning mixing up together and becoming this sludge that could blow the engine. I want to trade it in. My father took my notes and ran off to his mechanics. I think they take advantage of him He did give me the car. I need air conditioning for medical reasons. .I feel we just keep poring money into it. Any advice
