Thanks Richtazz & Jeffcoslacker. Wtih furhter disassembly I gained some access to the inlet side of the evaporator. I was plugged with a layer of dirt and fuzz and whatever else. I used a soft bristle brushh to reach up and get as much off as possible. Then I blew through it form the opposite side using an air hose and extension wand. I did not want to disconnect the system(s), heat and cold unless necessary.
As a result, there is a huge difference and it is quite acceptable now. Thanks again for the idea!!
