Another thing I will recommend is buying the original hose from the dealer. The after market ones or the ones you get repaired can kink especially if it has a U shape turn. the hose material is thinner started kinking / blocking restricting flow.
to say the least, the AC issue turned out to be a nightmare but it's all behind.
well almost. Now it has an issue with the condenser fan not going into highspeed with AC on . I sawpped the relay still nothing. It's only an issue when car is sitting at light or not moving but I'm just so over the AC dilemma I just live with it for now.
