- The perfect is the enemy of the good.
So the shop looked at a/c which actually wasn't on the list but topped off freon 3/8 lb low that's always good to know it's full. And he said the valve for the heater core is not closing when Max AC is on so that says vacuum leak. He applied vacuum to it and valve itself is fine (it's actually new... yeah I know new doesn't necessarily mean good, but he says it's good).
Other symptom which I had noticed just last week, if you have Max AC on, somehow the air feed to the center dash vent, where it comes out really strong, gets shut off. If you change the selelctor you can open it again but after a while it will go shut again and I would guess that is also a vacuum problem and probably once I find where the problem is it will likely cure both these things. AC is working well other parts of system are fine he says and it's not like I have no ac it's just that I need to trace where is it leaking which I would rather do myself if I can he said it's just charge by the hour if he does it and I would think it's not that hard (although I have no vacuum testing tools). Help?
