The blend door is moved by a rod connected to a cam atop the Blend Door Motor. Said motor is located under the passenger side dash.
It may be necessary to drop the ECM to see of the motor cam is moving and if it is still connected to the Blend Door rod.
I've had the little plastic connector break off so that rotation of the Blend Door cam could not move the Blend Door rod.

# 3 is the blend door motor.
