AC Troubleshooting continued...

Regarding the recirculation flap:  The doors share a common hinged brace so 
that when the cabin door is closed, the door into the evaporator box is 
open and vicey-versy.     As long as the spring is intact and the vacuum 
servo works, the doors have to function as designed.

Have you found any oily stuff anywhere around the compressor?  One problem 
is if the refrigeration oil leaks out, you can underlubricate the 
system.  I think I'd let a shop with tester equipment evacuate the system, 
check for leaks and, if no leaks are found, recharge it with gas containing 
the appropriate amount of oil.
