These systems use a vacuum line from the engine. Then there's a Check Valve and a Vacuum Reserve Tank. From there to the controls. Ford chose to put the Valve and the Tank IN THERE.The problem is INSIDE the HVAC cabinet. Here's My Thread About It.
It's invasive, but the quick check is to cut the Black Tube coming out of the HVAC Cabinet in the passenger side foot well. You see it curled to a cut end in this pic.
It's dead center in the pic, coming out of the black plastic, highlighted against the white firewall.
If you cut that, start the engine, and no vacuum coming from the end coming out of the plastic, the problem is as I described. Repair'll cost about $40 in parts and an hour or two's work.
Will help you any way I can.
