Both sides says the heater valve is open and your problem has to do with airflow.
One side says valve may not be opening.
Both sides cold says you have an obstruction, or air lock.
A mechanical failure of the valve will not show up in the diagnostics. On my '92, the cable was not shutting off the valve fully, so I had too much heat . . . in the summer. I re-connected the outer cable clamp with the valve firmly shut, and no problemo.
