Air Only Blows Out Of Floor

Often this is experienced after replacement of the battery.

Air only blows out of floor.

The air only blows out the defrost and floor not the face vents. No air from floor vents or defroster vents only front vents. My a c blows out dash defrost and floor only. On the astros when the heat only blows through defrost and floor it s due to a broken vacuum line.

Which part controls the vents in which the air flows. Like grumpy and others who gave suggestions on exhaust. My question is this. After installing a new blower fan motor the ac would only come out the defrost vents.

It works this way in both the manual and automatic modes. So i bypassed it. It does blow cold just cant get it out vents. We use cookies to give you the best possible experience on our website.

The factory vacuum check valve is very hard to get to. I know there is often a faulty check valve on the vacuum line but are.
