Be sure to check the mechanical temperature door for proper operation. Often the adjustment will slip and give a "blend" that directs the air across both the ac and heater cores and yields a symptom similar to your description. It can be a tricky adjustment and it is a mechanical wire. I would recommend adjusting for max ac. If you don't you will not get the max ac or coolest fresh air. Be sure to check all the vacuum motors for leaks. Checking to see if the system holds a vacuum after shutdown can tell you if there is a leak somewhere. The system should hold a vacuum for at least 5 min.

Any help would be great!
