    Hello,
    when I move my setting from floor to panel the air stream doesn't change. Is this electrical or vacuum operated?

    Welcome to the site! Will probably need to know what "year" and vehicle you are asking about.

    Similar Problem

    I get the same thing when I go from Vent to Defrost. It tends to continue to blow out the same vents.
    My truck is an 81 GMC k2500 4x4....My guess is something is stuck in the vents somewhere (debris) and not creating a seal.
