For you to shut off the "fresh" air from entering the car the TWO fresh air elements MUST both be closed..possibly a bad vacuum element is only partially closing off the fresh air door.

Take a look at the vacuum routing...SEE that the 2 recric elements, # 42 have 2 diaphrams each!

You need to start by doing vacuum tests at the switch-over valve OR at EACH of the 2 recric elements..you will need a hand vacuum pump w/guage to find the problem
