    My 1999 ford F 250 super Duty heat or ac will not blow out the vents. It is like all the vents are closed off

    I have replaced the switch.

    check switch by bypassing  it.  there is a blend door in heater that selects heat or cooling. check to see if it's has not stuck shut.  The heater & AC gets it air from a grill right in front of hood or at bottom of windshield out side. It will be very simple when U find problem.

    Maybe thier collapsing
