I just replaced the manifold hose, receiver/dryer, and updated the aux temp switch for the aux fan in my 300 SDL and the AC is working GREAT! My question has to do with what vents operate in the different modes for cooling. For normal operation, (not Bi-Level), my understanding is that the two center vents should be blowing cold air. There is hardly any noticeable air coming throught the center vents, but I do feel cold air being directed up towards the windshield.

Outside temps are only in the upper 60's - low 70's. Would the lower temps preclude the AC from blowing max air throught the center vents?
