Did you also test each of the 7 vacuum lines to each vacuum pod, and confirm all 7 hold vacuum? That will confirm your repairs were successful.
Next test is with the engine running, check for vacuum at the inlet of the 7-port manifold. If there is no vacuum present, you need to work backwards towards the engine vacuum pump and find out why.
If there is vacuum present at the 7-port manifold with the engine running (should be ~25" Hg), and NONE of the pods move when different modes are selected, you may have an electrical issue, or faulty pushbutton unit. With max cool ("EC" mode), the center vent should open, the footwell flaps should close, and the defrost flaps should close. With max cool and recirc switch pressed, the main air (recirc) flap should close.
