I cant see how a leak in refrigerant would cause the issues we have discussed here. weak air flow, too hot on set temps but still blowing cold on low.2nd trip to dealer; this time they say they found a ‘smaller than a pin hole’ leak in the refrigerant line and that there was no juice left. New line will take 2 weeks to arrive. Said they only recently knew to look for it as they found it on another one a few weeks ago. We shall see…
