Well, my daughter brought the car back on SUNDAY, and said the A/C worked great. I drove the car yesterday, and I have to agree with her. So I'm befuddled. Three years ago a dealer told the original owner it needed a condenser, etc., etc., and would cost $1,400 to repair. He dumped the car to me, and I took it to my Indy who could see where the dye leaked from the condenser. I didn't touch it until a few days ago, when I put the r134a in. The label on the can claimed that it could fix some leaks - can that possibly be true? Or maybe it was a very slow leak in the first place, though I had a different understanding. Until it stops cooling, I'm not going to do anything except replace the missing cap on the charging port.
