Does anyone know how an A/C High-side connector works
Hi, I screwed up big time. I was trying to do an A/C rechare on my dad's 1991 Mercedes 250 Sd. I think taht I accidently connected my hose to the high-side connetor (for some reason it fit, which its NOT supposed to do) and it started hissing and spraying green fluid. So I put the cap back on the connecotr, but now if I remove the cap, it still hisses. How do I reset that valve so it doesn't do that?
