Go from HI to LO and back, you need to see those values

Sounds like the blend motor is moving but it's not driving the flap. I would suspect the gears are stripped.
If i recall, the pot is the last in the gear set? If that's turning them the rest must be ok?

I'd have to go look at one, but if the POT is turning as indicated by diagnostics, as sure as heck the flap is not moving.

It's hissing down here, not about to walk to the barn to look this evening.I looked but i can't find mine
Did find some poly bushes though. And 2 coil packs
If you can catch sight of the motor then you might see the manual lever as it moves.
Failing that take the motor off, operate the flap by hands to see if the flap actually moves. You'll hear it thunk if so.
While it's dangling, turn the ignition on, see if the motor moves, you might need to adjust the temp.
Don't let it move much or you'll need to clear the fault

If the diagnostics show the value going from zero to 100, the the final stage gear is turning as that is what drives the potentiometer gear as can be seen in the photo. so if the blend flap is not moving, either the plastic drive shaft on the final gear has sheared or the keyway into which it fits has rounded off so there is no drive for the flap. It's also possible that the flap itself has broken off.

Flap cannot be jammed as the readings would not change unless it's jammed and the drive shaft has stripped.
