The van only blows out of the floor and windshield defrost. Before I put new blower and resistor it would work on all. If I put it for the air to flow from the dash it is still blowing from the floor and defrost. All speeds work now. Did I install something wrong? Do I need to re-wire the resistor? What actually controls the position the air comes from?[:@]

 

Relax, you probably accidentally yanked the heat/AC vacuum line off of the intake manifold while changing the blower. It's on the passenger side of the engine and has a check valve in-line.

 

The intake manifold side is connected. The other longer end has no home. When I plug the hole everything works fine.

 

That same heat/AC vacuum line feeds the cruise control and 4x4 system,if equipped. The end with no home could be for one of those if you have either.

 

I have neither

 

The vacuum line coming from the Intake comes to a T under the hood. A smaller line feeds to the driver side and the one with no home seem to have been held down by a bracket on the side where the blower motor goes

 

What if I just stuck a screw in it would hurt anything. When it is plugged everything seems to work fine
