My daughter has an 01 SL2 which has an air conditioner leak, I believe. I've added the "freon" a couple of times over the past year. I think she let it get too low now to add any more because now the compressor doesn't kick on and therefore doesn't suck in the new stuff. I think before when it was low, the compressor would kick on for a few seconds, then go off, but after the new "freon" was sucked in, it would stay on longer, etc. Is there a way to charge the system somehow without going to a dealer who does whatever magic needs to be done to get the compressor to come on when the system is too low.
thanks
