Help! Weird Heater Problem... heater valve?

I have a 2008 e350 with heater issue. I have searched the archives and assume the problem is the heater valve which seems pretty common. But I wanted to make sure based on my specific experience.

Several weeks ago, the heater INTERMITTENTLY stopped blowing warm air when the temp dial was raised. It blew cold regardless of the temp chosen. However, it WOULD blow warm air when the dial was turned all the way up to the red dot or when the front defroster was engaged.

Now, it it not intermittent anymore... that's the case all the time now. The air will only blow warm when the temp dial is all the way up to the red dot or the front defroster is engaged. If I reduce the temp one notch below the red dot, it goes back to 100% cold.

Given that it will still blow hot air in both of those cases, I am questioning whether this is still likely the heater valve or something else.

Any help would be much appreciated.
