I wasnt able to borrow a vaccum pump to check the lines yet to see if the center pod is bad.

OK - that's weird. You should not get any heat out the center vents ever, even with the #4 and #6 lines swapped. You WILL get some air out the center if you have the temp wheel in the middle and the system thinks it's too warm inside, but it should be cool air, not warm.
I really think you have a problem with one of the temp sensors, or the ACC pushbutton unit. What you describe is not a vacuum problem (although it would be good to test the vacuum pods anyway - probably at least one is bad.)
