Good to hear all is good. A little tip for others who may check out this thread, I might be repeating myself but hey.
Most people know to put the heater on hot when refilling the system. If you do it on the 80 then it stays on cold....unless you switch on the ignition. There is a cable at the valve but the cable is not linked directly with the 'hot' lever in the dashboard, it is controlled by a servo.
So ignition on, heater to hot, ignition off, and then it will hold in the open position.
