Problem solved! I decided to disconnect the ends of the small vacuum tube that runs from the 'T' valve on the passenger side in the engine compartment back to the throttle body (thin black tube with 'L' shaped fittings on each end). The intent was to blow through it to see if it was plugged, and if not, plug one end and blow again to check for leaks.
 
Well, when I pulled the fitting off the throttle body, the small tube disintegrated in my hand! So, I got a piece of 5/32" vacuum hose and replaced the small one with that, and now have functional AC/heat controls!

Awsome. I just did the exact same thing and have much more air blowing on all settings. I may even have heat now, but won't really know until it gets cold out
 Replaced a couple other ones that were looking shabby as well while I was in there..

I have found my broken vacuum line (L shaped ends) under the hood. Is the end that has to be connected to the intake manifold located on the left, or right side
of the engine when viewed from the front of the car.

I too found this hose. I think it ran from my firewall to the EGR valve or something. Either way it was practically disintegrated. Now I have SOME heat. Still not perfect..

There is little to no heat on the front heater. Rear heater works fine. What do I got to do to fix this?
