For this to work, you take the original actuator, or the new one (doesn't matter), and take it apart and permanently fix it internally on the cold setting. That way, the actuator motor is not turning against the blend door causing the torque stress on the hex side fitting which breaks the plastic on the blend door.
Unless the control module has a feedback loop in the CanBus system that would make this impossible, I'm thinking this could be another option to pulling the HVAC fuse or placing an inline power cut out switch on the actuator control circuit. It's a brute force way, but sometimes that works just as good.

That's why I am thinking of setting a hard limit at the dial.
You can always splice in a switch, in the power lead to the actuator.
