So a couple weekends ago I pulled the intake manifold to fix the blown plenum gasket and replace it with the Hughes Plenum Pan and what not, but once everything was all back together, only my defrost works:confused: . . . no matter what its on (except for off). Anyone have any suggestions? I'm baffled.

Check the vacuum lines going to the intake manifold on the side.

Any particular line I should be looking at? I know their all hooked up, but maybe ones crossed??

The one that goes from the intake to the brake booster...... from there a little line goes across the firewall and feeds the HVAC controls and the cruise control.


This is the line that feeds the HVAC

Thanks a lot:woot:!!! It was indeed that little line. It also fixed a helluva whistling sound at the same time. It took me a while to find that little hose, it was buried under my spark plug wires

Thanks again!!
