Where is the panel/defrost vacuum control motor located?

[Borcht Warrior]

Hey everyone, I have the opposite of the classic problem of the climate control only blowing out the defrost vents on my truck.
I can get air to blow to all locations except the defrost vents. I have done most of the pinpoint tests from the Ford workshop manual. I need to check on the actuator above but I cannot see where it is. Something must be blocking the linkage from returning to the no vacuum position.
