Pull out the EATC unit.
Disconnect the vacuum plug with all the pretty coloured hoses.
Connect a jumper hose from the black (vacuum supply) to the blue (panel door motor).
You may need to also connect the white (air inlet motor) hose to get cold air. Not sure about that.

Has anybody found a fix for this issue yet? Ac is stuck coming through defrost vent. O-rings have been replaced and the diagnostic is not showing any codes or 888.
I had a car with this. EATC was bad. New o rings didn't solve it. Swapping EATC did. Was around $20 from the junk yard.
