Default Blend Door Motor Position?

When the blend door motor is in the position shown should the door be open or closed? Thanks!

It doesn't matter - Programmer will cycle the door until it stops one way; reverse voltage and go the other. That's the calibration process which it undertakes after removing memory. If you don't get full travel, adjust the rod - in fact, yours looks like it could use a little more length, but it varies from car to car.
