Problems with climate control/ mode settings

I hope you can help me with this one! I have a 2000 Cadillac Deville…

I just came down with a problem in the climate control panel on the dash board several days ago. When I push the mode button to the center vent or center and foot vent positions. No air comes out of the center dash vents at all. The air is only coming out of the top of dash(defroster), the door vents and the floor vents... I do have a service manual so I am going by the fuse #’s and names they use in the manual…
So far I have I followed the procedure for re-calibrating actuators.
1. Turned OFF the ignition.
2. Remove the battery positive voltage circuit fuse of the Instrument Panel Control Module.
I was very unsure which fuse this was since none of them were labeled as the
Instrument Panel Control Module...
So first I went into the front Junction Block (under the hood) and removed the
#7 fuse labeled- Instrument Panel and I also disconnected the negative
battery terminal.
Waited over 2 minutes before reconnecting the cable and fuse. It seemed to work for about 10 minutes.. so I shut off the car and re-started the car and it wasn't working again...
So today I again followed the same procedure for re-calibrating actuators... in the rear under seat fuse box and removed the...
#2 fuse- Heater, Ventilation and AirConditioning Battery
#4 fuse- HVAC Blower
and the #33 fuse- Heater, Ventilation and AirConditioning Battery

None of these seemed to work... am I doing something wrong?
Someone please advise me if you know of something I’m doing wrong or if there is something else I can do?
Thank you,
Paul
