Well, the usual disappointment with my Car's AC performance.
Made worse when my Dad drives up in his old Chevrolet 1ton truck and asks me to top him up with R-134-A. Half a can later, with the SAME suction and discharge pressures as the Wraith, his is ICE COLD.
Not fair, I say...

Hi Randy,

Are your blend flaps and water tap working correctly and fully?

Are you getting icing on any of the pipes in the engine bay?

Blend flaps? Air always comes out the correct place. Coolant tap? Not working yet but it is closed and I have one of the hoses clamped.
