Using those auto part recharge kits are not the best way to do it. You have no good way to know if it was low to begin with.

I had to change out the little valve that opens when you connect the refill kit to the line. I think it is called a MacPherson valve. It is like a valve on a bicycle valve only a bit lager and they have them at NAPA. Once I replaced it I was able to fill my truck with new freon.

The system must be vacuumed after it is opened for any reason. Without being vacuumed it will never operate properly.
