That could do it, lol. Check your receiver, I believe it's supposed to show green in the round window when everything is good. The receiver is on the radiator bracket on the motor side and on the driver's side. Just follow the upper a/c line (a/c compressor hose...the same hose I'm looking for, lol).
Have an a/c tech look at it. Make sure there isn't green stains around it...like mine has. Did you know the new a/c stuff has dye in it already? It's green to show where the leak is and can be easily seen with UV light
