Air Wont Blow Through Vents

Air Wont Blow Through Vents My 2000 Camaro SS only blows air through the floor vents and the windshield defogger. If i turn on the air conditioning it does the same but I need to recharge that so for now I'm just concerned about ambient air blowing through the top vents.
-Recently i tore apart my motor to install my cam,heads,fast intake manifold and removed the Air/EGR systems.
-The map sensor on the back of the intake manifold is sealed tight and the 3 port connector that goes to the back of the manifold is plugged in. (one of the ports i removed that went to the EGR so i blocked off the cut tube with RTV sealant.
- I checked for cracks and leaks on the three port valve by the PCM as shown in this link and it is fine. None of the lines appear to be cracked or chaffing against anything to show a leak.

-I double checked all my vacuum lines and all are attached except the back end of the large rubber line behind the intake manifold known to crack. The other end of this tube went to the driverside large three port valve which connected to the ports on the stock exhaust manifolds.
Anyone have any tips on what to check/fix next? Thanks

Here is a picture of the only connection not connected to anything. Its the top line that splits into 2 seperate parts. The single opening on the left of the picture is not connected to anything, i figured it was fine since it went to the air system but what do you guys think?
-The hvac and brake booster lines are plugged in

that is your pcv lines, it goes to your ds valve cover and y's to your ps valve cover and then to the intake. The small vacuum line on the right should go to that plastic 3 way valve and one goes to the hvac box the other to the vacuum canister under the ds headlight

I checked that plastic 3 way valve and blew air through it to make sure it was fine. The three lines from it looked fine but i didn't tear through the convoluted tubing to make sure that they were. I saw minimal chaffing on certain spots near the driver side headlight but very minor.

If the vacuum line is attached to the hvac valve and the A/C vent vacuum line is attached to the hvac valve......the vents should operate.
The PCV system has nothing to do with the hvac vacuum system and cannot effect it in any way. If the engine is running, the hvac line will have plenty of vacuum to operate the vents, regardless of what's going on with the PCV system.

Did you do anything to the interior when you did all this? I had some issues with mine and it turned out that I forgot to hook up one of the bright multicolored vacuum lines behind the dash.

Had the same issue with an old car of mine. I just put a screw in the end of the hose where it brooke. I couldnt switch from floor vents to anything else. When i put the screw in it to create the vacuum wala it switched and worked fine. Just make sure the head of the screw is bigger that the hole on the hose otherwise you will suck the screw down.
