Where is a 2001 Cadillac mode door actuator located?

Asked by for the 2001 Cadillac DeVille
its located on the driver side, there is a black panel with two 7mm screws in it that you must remove. the actuators are up to the right. the one closest to the fire wall is the blend door,the one next to it is the mode door actuator.
how do I take it off without breaking the flang teeth?
