Boy, you guys have really outdone yourself this time!!! I don't know what else I would need unless it was someone to actually do it for me. I should be able to figue this out with all of the diagrams and instructions. I will let you know how it goes, it might take me a while though, kids in school and stuff.
Thanks Again

When it comes to hot weather and AC issues, I try to provide what I can to get folks cool, again (Phoenix has been known to have some warm weather occasionally ) and all of this was already on here anyways. It was just a matter of trying to figure out what your problem may be and what options may be useful for you. I didn't want to overload you with all this info if you didn't need it. Listen for hissing or do some vacuum tests like Imidazol has explained. No reason to go through this if you think this is not the problem, but it is the chaepest and easiest thing to try (accessability-wise) before moving onto the next step.
You can do this!!!! Again, it is not hard just..........awkward (you'll see what I mean when you have your passenger seat pushed all the way back, with the back reclined fully, while you are upside down in the seat working on the fix from below the dash. )

Good news/Bad news
Well I cut the vacuum feedthrough out and, viola, air comming out of my vents when I want them to. I don't think I have ever noticed the air switching from defrost to floor to vent so quickly, within a second it seems like. Before it took a good 5 or 6 seconds to achieve that goal. BUT...............
I still don't notice a difference in air velocity between recirc and not. Am I incorrect in "remembering" that I could hear a difference when I had recirc on.
Insight?
Thanks

Thanks for the tip, I will try that this weekend and let you know what I find.
Is the recirc door #4 in the diagram, if it is, how in the #$@ do I get to it????
If the recirc door is NOT #4, where might it be in the cobweb that we call our dash?
Thanks again

No....that is the air mix door actuator which controls the amount of heat and cold you get. The recirc/fresh actuator and door are not shown on this diagram.
Again, I have never tried to locate my recirc/fresh actuator or door, but my understanding is that it is up above the gas pedal (but maybe centered behind the dash). If you were to follow the orange vacuum tube from the passenger side (where you removed the connector), up into the dash, I am assuming it ends at the actuator. The digram that imidazol posted above shows somewhat the position of the actuator and he describes it in his post, so I would follow his information. If you look at your group of vacuum lines going up into the dash, you will see the harness connector like in the diagram below holding the vacuum lines. Then they split off to the different actuators. Follow the orange line to the door.

So I tested the vacuum tonight,
If indeed the orange line controls the recirc, then I have a problem. I took the splice off of the orange line and checked to see if there was vacuum coming from the controlller (THERE WAS). I turned the recirc OFF, waited... waited...waited... waited...waited... waited... the vacuum never shut off from the controller, but I swear the recirc is not working.
Here'* the deal, (if I undersatnd things right) You apply vacuum-recirc door moves and you have recirc. You shut vacuum off-door goes to nomal position, no more recirc. So I must have a stuck door right? (along with a bad controller maybe). When I unhooked the line, there would have been no vacuum going to the door so it would return to the normal position, (no recirc) correct? I would rather be with recirc on all the time than never have it. Let me know if I am way off or if my theroy is right? Any other tips would be great also.
Thanks a bunch.
Oh ya Go HUSKERS!!!

Everything you said is correct. Vacuum applied moves the door (or valve as they call it in the FSM) to the recirc mode and draws air from inside the vehicle. So, if you "de-select" rcirc, then there should be no vaccum at the line. Since it sounds like you have nacuum when recirc is "de-selected", then the manual leaves the technician with the only option of replacing the programmer. If, howver, you do not have vacuum, then they direct the tchnician to ch4ck for a binding valve(door) or a faulty actuator. Sorry, I don't have any better news for you. I did find the Test section where it does say that ther should be a "blower motor noise change as the system goes from outside to recirc air".
