Default Re: Air Coming thru Defrost Vents

If your vlower only blows air through to the window and footwells, you have lost vacumm power.........see the diagram. You either lost the vacuum contrtol in the engine compartment or the yellow vacuum hose has pulled off the vacuum motor than changes air from the window/footwell to the dash vents.
